Unable to sweep

[SuperCAD]

I have a quick question about this. Why are you going to such great lengths to develop a perfect thread in 3D, regardless of CAD program being used? All it does is add a ton of data to the file making it very large. There are easier ways to designate a threaded feature with annotations. Also, you can cheat by downloading a fastener that has already been modeled from sites like McMaster Carr.

Why are you going to such great lengths to develop a perfect thread in 3D, regardless of CAD program being used?

1) Because we can (although technically, apparently we can't)

2) Because it part of lesson or tutorial somewhere.

3) Because helical sweeps are not uncommon in mechanical design.

The same can be said for anything drawn in 3D both in terms of files size and ease of annotation compared to a 2D representation of the same object(s).

The point being that it's completely unnecessary to draw perfect threads. Threaded features are much easier to create in SolidWorks, and I'm sure it's easy in Inventor too, but even SW recommends that you NOT create perfect threads due to how much it adds to the file size. So again, why do it?

 

It's actually easy to create a perfect thread in AutoCAD, it just involves a lot of steps. The end result, however, is not too impressive and it could cause the drawing file to become unusable/unstable.
