Mesh - Edge normal vector

[Tom_Newsom]

This appears to work like a dream. Thank you very very much

And yep, it’s frustrating because I definitely love thinking about these kinds of things - maths and geometry and the organisation of data, and I have enjoyed the limited amount of coding I can cope with. But if I can’t see it all in front of me with the flow of data represented visually, it all just fizzles away form my mind like snowflakes in a storm. Believe me I’ve had decades to try!

PS:

They are entirely appropriate for the shapes I’m making
(and doing the same thing with surfaces is WAY slower I’ve found)

You need a C# Sensei. Search Yellow Pages (and prepare yourself for some pain).

BTW: the latest C# is still very entry level. For instance clash checks (general case: any Mesh) are MIA etc etc.

Funny to be coming back to this. I just wrote a script that determines the edge normals of a mesh. How was it that you were deciding how to truncate the corners of the offsetted faces?

[Tom_Newsom]

Quickest answer is to screenshot the relevant pages from my report (the project was for my Masters)

It worked well and let me make this model:

Nice!

But, no, that doesn’t help me. I looked at some of the old script and it seems that there you just used a champfer length that was arbitrarily long enough.

I gave a shot at emulating your script. I managed to circumvent the need for edge vectors by creating offset surfaces with Plane Region:

a component, I have to say, I have never actually used before.

[Tom_Newsom]

Correct. I just found the spot with greatest convexity and adjusted the chamfer till the corners didn’t intersect. Nothing fancy!
