Re: Simple engraving question

I tried for quite a while with sketches, clones of sketches and more, but nothing showed up in the BaseFeature list. Finally I hit the Ok button of the engrave operation anyway and - surprise - the path was created :) . I was successful wit a sketch on top level of the tree using this as 2D geometr...

The Engrave operation is very focused on shapestrings; when I tried to use it with my art it generated nothing beyond the prefix and suffix codes. What operation should I be using?
The engrave op can also use a sketch or individual edges from a model or a sketch.

Re: Rotated holes result in different sized Helix tool paths.

There's indeed something funny happening here. The original diameter for me is 3.988, and after the recompute it's 4.000, and if I open the Helix again it's 3.988, again. In fact it was 4.000 exactly once - I'm almost tempted to chalk it off as wishful thinking. My testing is rather limited, I keep ...

Re: Rotated holes result in different sized Helix tool paths.

Its really getting on my nerves that there is so much resistance to change in this forum, there is always a lot of blow back even when fixing things that are clearly bugs. your definition of "clearly bugs" seems to be combination of personal preferences and assumptions. How about some engineering p...

Re: Rotated holes result in different sized Helix tool paths.

AFAICT the issue is not with Path, it seems to be with the model. If it is with Path, write a unit test that shows the problem and proves the fix.

Re: Rotated holes result in different sized Helix tool paths.

I'm not able to reproduce the issue other than verify that your file @chrisb does have that issue. Attached is the file I used to create some unit tests. They rotate the body in 5 degree increments and the resulting helices are all correct. They also rotate the Job's model clone in 5 degree increme...

First you have to use the inner faces, not the edges, but it is more complicated, and finally it may be no issue at all.
That's what the unit tests do, I verified.
EDIT: Also, I use a blank FC config file, default settings, so PDN is 28.5° and 0.5%

Re: Error in Helix operation

The issue mentioned in the OP is solved. It was my fault to use a tool bigger than the hole diameter. Sorry for the noise. i don't consider this to be noise. Input data sanitation should happen and an assert is not the way to go about it. No input values should result in an exception. (The issue in...
