RE: 3D software for mechanical drawings.

Tkainl,

If you are doing mechanincal design/drawings and you want to get into 3D, parametric solid modeling is your best bet.  As far as which one is best, every person on this site will have a different oppinion.  You can start by asking yourself a few questions like, "how much am I willing to spend?".  Also, depending on "what" you are designing will help deside which is a better fit.

Are there any more details that you could share with everyone?

RE: 3D software for mechanical drawings.

Tkainl,

I was a former ACAD user and have recently switched to Solidworks. Although the initial step was tough it wa well worth it. There is a book called Solidworks for AutoCAD users. I would recommend taking some basic course just to get your feet wet and then you'll be off to the races. PRO Engineer is also good, but I found it complicated and buggy, so for now I'll stick to Solidworks.

Good Luck

RE: 3D software for mechanical drawings.

I have used 2D AutoCAD back in 1987. Then MicroCADAM in 1991. I remmember back on those years I was just refering to a simple documentation to learn AutoCAD all by myself. And it take few days training for MicroCADAM.

Then come Pro/E ever since 1994 (Pro/E R14) where I struggle to learn 3D creation for 5 days. And continue struggling for years. And todays I must confess that Pro/E is the best 3D solution in term of rich of features/ functionality and stability. Back at the time of 1994 to around 1998, I would called Pro/E as the market leader with that kind of innovative 3D methodologies of modelling.

Intergraph with SolidEdge (and now UGS) was following Pro/E exactly for ages without much success until maybe recently. Solidwork is of no different except it is slightly easier to use with newer GUI. The same kind of marketing strategy with SE. But how true is this "easy to use" claim by the software vendors?

When I was evaluating softwares for my company in search for something to get my job done few months before, I came to know Inventor. I have handson with our company data for the three much "affordable" 3D solutions to see their ability to get my job done in the area of creating complex machinery.

Autodesk Inventor stand out to be the winner. There are many detail in the evaluation process but basically ease of use to get the job done is one of my criteria.

Inventor go into my nerve as an long timer in the industry for it innovative user interface. For one thing... Autodesk finally serious with 3D business and meet my 1st time good impression of my earlist experience with AutoCAD 2D back in 1987.
And since they own AutoCAD, it is natural that 100% compatibility to Inventor can be done by Autodesk. Inventor continue to inspire me with 3D modelling for its modern software design (I wouldn't said so for the next few years unless Autodesk continue with its innovation). I felt more
comfortable to invest with company that would be around the industry for ages instead of some that was bought over by others. Those 3D solutions that were bought over are not in full control of their software development. The owners of its higher end solution take control instead.

SO think about the above few facts before you invest.

RE: 3D software for mechanical drawings.

Microstation Solid Modeler is by far your best bet compared to Acad and Solid Works.  I used it for 7 year.  AutoCad is out.

RE: 3D software for mechanical drawings.

We got instant productivity from Inventor.  I sent my guys to the training course but couldn't go myself.  I'm designing complex models and making drawings in one tenth the time of 2D work.  Bought ProEngineer several years ago.  Inventor is much easier to work with.

RE: 3D software for mechanical drawings.

Autodesk Inventor is very simple to pick up.  I know of more than one person who never had any 3d package experience, went to Inventor training, and now is booming along w/new complex designs from Inventor.  Inventor is the way to go.

RE: 3D software for mechanical drawings.

Hi Tkainl,
    It all depends on what type of work you are handling right know. If you are in a Automotive/Aerospace industry and doing a detailing job for them on AutoCAD and you would like to move on to 3D CAD then for an industry which handles complex curves and surfaces I would suggest you go ahead and learn CATIA as it is the much preferred CAD software today.But if you handle most jobs which could be done using basic shapes like a prism/cuboid/sphere etc and there booleans then I would suggest you learn Solidworks.
 I hope I could be of assistance to you.

RE: 3D software for mechanical drawings.

Dear tkianl (Mechanical),
           There are too many 3-D CAD softwares in the market. Generally these are classified  as High End, Mid Range and Low End software.
            Pro/Engineer, CATIA, Unigraphics, I-Deas and AutoCAD Inventor are high end softwares.
          People say (I too) Pro/E is  most powerful for complex modelling and large assembly handling. CATIA is improving very fast and best for surface modelling. UG is also well reputed. I-Deas is very fast in modeling, assembly and drawing and cheaper too. You are a user of AutoCAD so you can easily migrate to AutoCAD Inventor.
         Solidworks is neat, fast to work  and fast growing software. Solid-Edge, IronCAD, CADKEY, AutoCAD Mechanical Desktop, ThinkDesign(It support voice interface), Rhinoceros, Pro/Desktop  are other softwares. All have some plus point and some shortcomings.
     There are some freewares also. Try links Tenlink.com or mcadcafe.com to get freewares and trialwares.
     If any other doubt, write to npsingh@engineer.com

RE: 3D software for mechanical drawings.

Auto Cad has got some great features using which u can create powerful 3D drawings. I have personally created a 3D model of an ic engine(micro ic engine) and the exploded view of it, but it is little complicated, so if u go fo UG or Pro-E it has got lot of features and flexibility to do the same

RE: 3D software for mechanical drawings.

Try IronCAD... very few people know about it but is by far the easiest 3D package to learn. You can pick it up in 2-3 Days doing the tutorials. It was recently given 4.5 Stars from Cadalysts mag. It uses both the ASICS and parasolid modeling kernels...

see... http://www.cadalyst.com/reviews/software/cad/0701ironcad/ironcad.htm

RE: 3D software for mechanical drawings.

Also, I must say that anyone that is praising AutoCAD does not understand how far solid modeling has come in the past couple of years. AutoCad is a joke compared to the new software that is available... I have not tried Inventor but it seems similar... Pro/E is very expensive and hard to learn.. go with one of the newer packages...

Solid Edge and Solid Works are very good choices but not as easy to learn as IronCad...

RE: 3D software for mechanical drawings.

Our design group just completed an evaluation of SW (2001) and Inventor (r5), using weighted categories such as "Productivity", "Standard Features", "Ease of use/learning curve", "Step Compatibility", etc...

The hands down winner was Inventor, although many categories were "ties".  Some of the strengths of Inventor were:

-More intuitive user interface, with fewer dialog boxes and fewer mouse clicks.  Gesture based sketching, glass box, "expert" and "learning" modes, more consistent interface with (far) less clutter.
-Ability to handle large assemblies (SW requires that parts be marked as "lite" to just load the graphics, but you can't work on them in that mode, INV handles this in the background: all parts load graphically, but as the cursor goes over a part, it (transparently) begins to load the geometry of the part)
-Built in support for concurrent engineering (several users can work on a model at once), this is a shortcoming of SW.
-Better STEP file import: the colors and part names of the imported component were preserved, and the geometry was immediately useable.  SW required the use of "FeatureWorks" to "repair" the same model.
-Adaptivity: the SW guys had a contrived example showing how they could do the same things that Inventor does: this is true only to a very limited extent, explore this carefully in your own eval...

Everyone should do their own evaluation, as each product has particular strengths.  Don't let past experience with Mechanical Desktop cloud you judgement, Inventor is a completely different product, not a derivative.

RE: 3D software for mechanical drawings.

Hi,
    i am a mechanical engineer by qualification. I done my degree in 1998 but switched to software profession.
But still mechenical stuffs attracts me a lot.
Can i  start learning Some 3D mechanical drawing software now( i have now totally forgotton all mech stuffs)
I mean how difficult it will be...
Although it depends on person to person but still any suggestions...

thanks

RE: 3D software for mechanical drawings.

Most mid-ranged 3D software is windows based... if you are comfortable in the windows environment, it shouldn't be too hard to pick up on.

As for specifics and standards, grab a Machinery's Handbook and a copy of ASME Y14.5M.

RE: 3D software for mechanical drawings.

We are in the process of changing from Autocad to Solid Edge, since January this year. I can tell you that 3D rules compared with 2D. We have a large number of Autocad drawings and translating them to 3D using Solid Edge is very simple with little hassle. Generating new designs is now FUN, it has made working a pleasure again.
The 3 main things to remember when changing over from one to the other is to allow yourself time to adjust. If you are under a great deal of pressure at work then things can very quickly get on top of at the start. Secondly, spend some money and time and complete the foundation training course, (4 days for Solid Edge), it is worth every penny in outlay and time spent. If you don’t then you will not get the best from the system. Finally you must have the best hardware that you can afford, especially if you are modelling large assemblies or components with large numbers of patterned holes ore cutouts.

RE: 3D software for mechanical drawings.

Wow, I never knew ProE was had so much acclaim in the industry.  I took the class last year and I have a pretty good handle on it now.  I think it is way easier than CATIA.  Then again I just took the CATIA class so it is still new.  But ProE is definitely a powerful tool....go for it!

RE: 3D software for mechanical drawings.

A friend of mine is a hardcore autocad user, he says the solidworks package is a very natural progression into real solid modelling.

RE: 3D software for mechanical drawings.

hi there tkianl,

This type of question is always going to raise some debate.  We use solidworks mainly because of experience had at University.

IMHO 3D modellers are all pretty good now, ProE used to lack the 'nice' GUI of SolidWorks/Solid Edge but has now remedied that.  Inventor was spawned initially using a 2D environment to create 3D models until Autodesk realised that a new package was needed with solely 3D modelling in mind.  ProE & SolidWorks/Edge etc have been around for sometime - perhaps some newer packages may be playing catch up??  - my opinion only.

My only other thought is make the vendors work for their money! You are going to outlay some serious cash on any 3D programme - get them in and ask them to show what it can do for your application!

RE: 3D software for mechanical drawings.

Hi there,

I've been using Unigraphics for several years and find it excellent for creating complex engineering models such as turbine components. This is high-end software though and the cost may well be prohibitive for some people. I still use AutoCAD for the 2D stuff though.

However, I also have a copy of Rhinoceros and this is suprisingly good at both 2D & 3D work and it's less then $1k!!! I also use it for translating various CAD formats and is worth the cost for that reason alone! If you are proficient with AutoCAD then you'll have no problems picking it up.

RE: 3D software for mechanical drawings.


I have recently spent two weeks reviewing 3D CAD packages.  I did not think ProE is best for our needs, Solidworks is cheaper and easier to use.  (a 2 week break over Xmas was a good test as to how easy it was to pick something up again).  I am not a CAD jockey but use it as a tool to design and communicate.  Ease of use was paramount especially after days of "non-use".

You must trial any package and see what you want and what you can persuade your company to buy.

Prior to solidworks I used ProDesktop - because it was free.  Check out www.ptc.com.  If you don't want to spend money and still have great 3D capability then get ProDesktop.  Word of warning- it is ackward at dimensioning drawings.

I am C3P (Ford) Ideas certified and have always hated Ideas with a passion.  This was largely to do with its instability.  However, I have since learned that the platform/machine on which the software is run makes a huge difference.  I just never stayed long enough with my previous employer to be converted back!

ProE Wildfire is the newest release form PTC.  It is more windows based and seaks to be intuitive with what your doing.  

get the vendors in and get them to do the hard work.  I would always push for a free trial.  I had a 1 month trial of ProE and Solidworks.  

Hope this helps,

Phil.


RE: 3D software for mechanical drawings.

billybut
  - As most CAD users, you have moved onto a new tool (UG) but still keep the old faithfuls around just in case.  A question:
  EDS is really promoting the Unigraphics Die Designer package.  Is it as good as they say?  We all hear the stories, and watch the 'smoke and mirrors' demonstrations, but does anyone have any real experience with the DieDesigner package that they would like to share?  I have worked with a number of other, so-called die design packages, but they are often more problematic than helpful.  Has EDS managed to buy the pieces of what noone else seems to be able to build properly?
Anyone?

RE: 3D software for mechanical drawings.

I have used Solid Edge, Solid Works and Pro-E software.  I have stuck with Solid Edge for a number of reasons.  One of them is the drafting portion of it.  Anyone will tell you that you probably spend more time doing drawings than anything else, mostly to ensure that you communicate absolutely everything and tolerance everything properly.  Solid Edges' drafting package is very easy to use, which allows you the time necessary to work out the information you are providing, rather that wasting time setting up the drawings.

RE: 3D software for mechanical drawings.

Hello fellow ME's,

I am a degreed mechanical engineer that has spent a majority of my career in the manufacturing sector. Since
I have no experience in 3D modelling I am interested in learning it on the side. Which 3D solid modelling package would you guys recommend for ease of learning? Career potential/Job opportunities?

Additionally, what would be the best way to learn a 3D modelling package? SolidWorks offers a 4 day class for level 1 and a 3 day class for level 2. Can a novice really learn solidworks/3D modelling that fast? Cost is $2000. A nearby University is offering ProE, I can get certified in ProE in about 6 months, cost=$2200. Which would you recommend?

All comments and suggestions are welcome.

Thanks in Advance.

Paul



RE: 3D software for mechanical drawings.

Paul,
Depending on how you define a novice, yes, you can learn such a package's basic's in such a short time. BUT, imho, you will have to learn it by doing, using it in a job. The basics of 3D design are simple, but you will have to get them right before you can be of any use in industry. How to model a part, how to set-up an assembly (top down, bottom up), how to manage the files. You will know how to make a good drawing I presume.
The modern 3D packages are rather intuitive, so learning your way around is rather simple. As always with software nowadays, it's not the knowing 'how to', but the knowing 'what to'. If you know what you want to do, and know it can be done, most of the time you will figure out how to do it. The courses are mostly rather fast, with lots of examples, just to show you what the package can do, to get to know the method of operation. In working with the package you will master the things you have seen.

If you want to learn it on the side, I expect your company doesn't have a 3D package. I personaly think it isn't much use to fidle around in an illegal version at home, modeling your kids toys or something. You will lack the interaction regarding your work, will lack the challenge of altering your design. But if you want just a taste of the 3D-world, go for the cheap course. It will give you a good feel of what modern 3D packages can do!

Regards,

Pekelder

RE: 3D software for mechanical drawings.

You didn't mention if you have CAD experience of any kind. I pushed a pencil for 20 years before starting to use Cadkey, but only in a 2D environment. It was very easy to learn since we used it in a similar fashion to hand drafting. It then dawned on us that Cadkey had 3D capability all along and we transitioned easily to first 3D wireframe and then solids. When Solidworks came along I took an entry level class at a community college and learned quite a bit. This cost roughly $300. We now use Solidworks exclusively for new work and it has made my job fun again.
If time is a main consideration, the concentrated classes may be the way to go and you also would have the "sheepskin" to refer to on the resume.
An alternative would be the Solidworks "Student edition" which works for 24 months and sells for $200. This is also bundled with a book for $230. Teach yourself, but no sheepskin!
https://www2.journeyed.com/cgi-bin/sgsh0101.exe
As I understand it, this is full featured but the file format isn't compatable with the normal version and prints have some sort of watermark designating you as a "learner". You also have to prove enrollment with at least 6 credit hours.
I can't comment on ProE other than the learning curve will be steeper but the sheepskin will likely be more marketable.

RE: 3D software for mechanical drawings.

Iv'e used 2d Autocad for the last 6 yrs. Recently our company bought 2003 Solidworks, I went on 2 training courses.

It has been a love /hate relationship.

This is what I found;
SW crashes a lot, eg when using a 'design table' you have to open the table each time after editing a part so that it can update. If you try to save before doing this it crashes
I miss a real 'Undo' command
I really, really miss the 'Snap' command.

The station is beside my desk. Every day I hear : '£$%&, all I want to do is click on this, very simple and it won't let me.'

Time will tell. Good old Autocad, it's like that old car you don't want to get rid of.

RE: 3D software for mechanical drawings.

Hello Again Fellow ME's!

Thanks so much for your comments and suggestions regarding 3D solid modeling. I have found all the suggestions very helpful and beneficial.

I have one more question for you guys: Which 3D solid modeling software is more beneficial in terms of landing a job, Solidworks or Pro/E? Or other?

Thanks in Advance.

Paul (PCS36@yahoo.com)



RE: 3D software for mechanical drawings.

SolidWorks. Thats all you need to know.

RE: 3D software for mechanical drawings.

I'm surprised no one has mentioned rhino3d (rhino3d.com), which is a nurbs modeling program  have been acad user for about 15 years and got into rhino about 5 yrs ago....

to recommend it:
1, developed in open beta, so improvements were/are fast and on target. (excellent user group access)
2.  if you have any 2d computer experience, learning curve is not very steep.
3.  can read/write to a *huge* number of other formats, including acad, illustrator, bunches of CAM programs, etc.
4.  reasonably priced (IMHO) for productivity
5.  chock full of nifty utilties like "make 2-d drawing", and 'create' section
6.  full rendering capabilities with plug-ins, including raytracing.

in fact only thing i don't like about it, is you can't control line weight, so for presentations, i usually export to illustrator or acadlite.

i, too, urge you to get some of the free trial downloads and compare.

good luck


RE: 3D software for mechanical drawings.

Hello Again Fellow ME's!

I have been busy learning Solidworks and I am finding it to
be fairly user friendly. However, the manual that I am using does not have many parts to draw. Do you guys know of any manual that provides many 3D parts to draw and learn from?

Thanks in Advance.

Paul (PCS36@yahoo.com)

RE: 3D software for mechanical drawings.

Paul,
For learning parts, I have found that the easiest thing to do is pick up things that you deal with every day.  Set them on your desk with calipers, mics, and measure them.  Then try different ways to come up with modelling them.  I have been using Solidworks for the past 4 years, and as I look back and some of the things I have done, I am amazed at how difficult I modeled them for coming back and editing them.  To the point that I have completely redone the model in less time than it would have taken me to edit them.

Find things thats shape interests you and try to model them as they sit in front of you.

Just my $.02 hope it helps.
