Assembly Question
Assembly Question
(OP)
Ok I trying to design and model a big project in solid works. To start with I know a few things.
Where and how it will mount to an existing place on the truck. And where the wheels will touch. I need to design everything in between. I figured I should do this is Assembly mode so that everything has relations with each other so if i change like the length or height it will change to middle components by itself.
Basically what I wanted to do is built the front and throw down so basic wheel and then build in between. Is this the way I should be doing this. Or is there a better way. Can you add Assembly relations later. Note: I don't mean mates and mean changing the part.
Also if this is the way to do this then any tips or tutorials. If not the how should I be doing this.

Part of the problem you may run into is the number of components in the sub-assembly you'll want to control. You need to watch out for circular references, among other things. Too many "links" can also cause performance issues.

RE: Assembly Question
Having designed and built many 300 to 1500 components assemblies I suggest using many subassemblies. In many cases doing a basic layout sketch of fixed areas and using this as the template for all other parts and assemblies by doing a file save as or copy and paste. Try not to have any external references. When the next version of SoldWorks is installed there will be update problems with older assembles and drawing pages.

I think this method is cleaner since you don't have the additional layer of assembly references, and it's clear which way the relationship is supposed to go (all parts reference the master).
This technique was limited before SW08, as you could only show solids, surfs, and datums. The ability to show sketches really lets you take advantage of the technique.

I include the CAD file I got from the manufacturer.

I try it some more and see what I can do.

Thanks again!

Thanks. Just don't want to create any bad habits.

1. Clearly define the goals you want your product to achieve and stick to them.
2. Clearly define the space you must design within.
3. Try to anticipate variables that may arise, and come to the most logical conclusion for your application and available manufacturing capabilities.
5. Understand the various design methods for the type of part you're trying to create.
6. Start with the internal parts and design around them.
7. Sometimes it is best to mate to a "master assembly layout sketch," but sometimes not.
8. Designing parts with external references is generally not a good practice.
9. Always make sure your sketches are fully defined before you create a feature from them.
10. Don't change anything, ever, to the parts if you need to make revisions after manufacturing. Save as a new, revised part.
Actually....11. structure your working folders so that you can find things easily.
Also, here is a picture of what my assemblies typically look like before I get crazy with them.

BTW I must say I have used many different forums for a variety of different things and this is by far the most helpful and pleasant forum I've used.
