Adding stiffeners
Adding stiffeners
(OP)
I have a problem adding stiffener to the object as I could not sketch a diagonal line and placing it in the centre of the workpiece when sketching in the 2D plane. How do I place the diagonal line in the middle?





RE: Adding stiffeners
Is that all that you can tell about the geometry? Why can't you find the center of your stiffener?

1/ pick the plane to sketch on, in this case ensure your plane is in the centre of the workpiece.
2/ In sketcher there is a useful sectioning Icon, using this you will see where the centre of your stiffener will be as the line is drawn, you can dimension to the object edge geometry as a guide. Also I would draw the diagonal line ensuring the end points do not touch either surface, somewhere close will be fine, in 3D this will be projected to the surfaces.
3/ Exit sketcher and pick the siffener Icon, choose either side to add material either side and all should be ok.
Hope this helps........
RE: Adding stiffeners
Secondly, whether you are, or are not, are you having problems establishing planes, or are you having problems with the stiffener function?
I'm getting mixed messages from your post. Since the chicken usually precedes the egg, why don't you confirm that you DO or DO NOT have a sketch plane defined...

Your sectioning Icon is there within the sketcher environment, but, you may not have the correct toolbar enabled, to do so, go onto your tool bar area and right mouse click, from here you can then select the VISUALISATION toolbar.
The sectioning Icon is in this set, looks like a red plane through a blue surface, hover your cursor over it and it should read "cut part by sketch plane".
This will be active when you click it but can be toggled on or off from within sketcher.

I didn't mean to be insulting earlier. Forgive me if I come across as blunt. I just was trying to figure out what your perspective was, because so many people come across the forums with the precept of knowledge, when in fact they have none. If you're a newbie, it's always good to identify your skill level to those who might be serving you. It's a matter of getting someone to focus the answer specifically on your issue, and not confusing you with other topics. (which even happens to those of us who have been around for awhile)
And there's no shame in being a newbie. Welcome to our world!
As for the answer to your question, I respectfully concur with the last 2 responses...
Hope that helps.

Does the thread show up in a end view or side view of the threaded hole?
RE: Adding stiffeners
your said earlier: "I have turned on the generate threads but it is still not shown in the 3D workbench but as dotted lines in the 2D drafting page."
The dotted lines are the symbolic representation of threads on a drawing. That's how CATIA does it.
If you want a true representation, then you have to model the thread in 3D. Alot of work that takes alot of space, and is usually not worth the effort.
RE: Adding stiffeners
Someone who is looking at the drawing must be thinking something is wrong with the drawing as the ismeometric views does not tally with the other views which is shown as dotted lines
RE: Adding stiffeners
To add to what you said - not only is that "how CATIA does it," that's how the rest of the world represents threads according to *published* standards. It is, after all, still a *drafting* workbench, based on *drafting* standards.
It should not surprise, nor disappoint anyone that Catia does not represent threads. Why, would anyone in their right mind devote any amount of time or resources to such an effort as programming a true depiction of threads, knowing that there would be absolutely no gains to be had, even if it were possible? Thread representations on a 2D drawing are NOT value added, in 99.9% of the cases.
Of course, the same could oft be said of the 2D itself...

This is exactly what I thought too...
RE: Adding stiffeners
No disrespect meant to anyone - I know, being in business for myself, that customers may require it - but nonetheless, I stand by my statement, that there is no real need to develop such a thing for use in a workbench, as someone expressed disappointment over not having it.
Pictures are nice, but not always expedient. If we ever go to full 3D representations, which would be nice, I would love to see thread creation more automated. At that point, I would suggest that standards would absolutely need to be changed, and full representations should become the norm. We've got a ways to go...

RE: Adding stiffeners
I'm still curious what a thread looks like in an isometric view - especially since you said Pro-E can do it. Can you attach an image for me?
I know how to 'fake it' manually on the board for pictorial representation (not exact), and I know how would 'fake it' with any CAD system. What does Pro-E do automatically?
thanks, ...Jack
RE: Adding stiffeners
Pro-E is not the only cad package that alows you to creat full detailed threads. UG alows you to creat both symbolic and full detailed threads in both 2d and 3d.
