In the part modeling the manual thread will be cut through helix and sweep-cut feature. My concern in how to cut the manual thread in the assembly modeling.
Can you please help me in this issue.
Thank you in Advance.
Can you explain why it needs to be cut in the assembly? Just curious. Also, keep in mind that in-context relations will also slow down your rebuild times and general performance in assemblies.
Also, as others have mentioned here, you really never want to model the threads as a swept cut with a helix. Swept cut threads make the processor work harder, which can slow down the performance of your models. In large assembly's it can make a really big difference. The first preference should be a cosmetic thread, then your second should be schematic threads (a revolved cut with a linear pattern). Last, would be the swept cut method.
Is there a reason you do not want to use the hole wizzard?
Thank you wayne schafer for the reply.
Actually our customer need manual thread instead of cosmetic thread. that is the reason we are trying.
Create a helix for proper pitch and diameter for the thread size. Make plane normal to point & curve of helix. Sketch thread profile onto this plane. Helix is path, sketch is profile for sweep feature.
I don't think you can make a helix in assembly mode. I might be incorrect.
That is correct, Wayne, but you can create it in a part, then in the assembly create a 3D sketch and convert entities.
You might check out fake threads, which is what we ended up using. It is basically a revolved cut of one thread and then linear pattern the rest of the threads. Usually good enough for most applications adn uses far resources to make and store. Fast adn easy.
If you want a physical example of fake threads, download a 3d solidworks cad from the mcmaster-carr website of any straight threaded screw or fitting.
Actually I do this to the models and this is very easy on the processor, that is why we choose to do threads this way. I really hate those cosmetic thread, guess because I started out on UG and the symbolic threads are really the best way to do threads. So we decided to go the way of the fake threads, at least we have something that some what resembles a thread. WE are a bottom up manufacturer and many of ouor parts are used in many different assemblies. FYI.
Thankyou for your reply.
Basically we are generating the threads by using helix and sweep-cut in part modeling. This is the first time i need to generate the thread in the assembly modeling. That is the reason i was trying, may not be know how to generate the manual thread in assembly modeling.
You are correct, atlast i generated the thread by using revolve cut and linear pattern.
