Default some nice to haves

i made some notes

1.
extrude along multiple paths. + option closed holes.
usage at train tracks switches.

2.
units, me most working in cm or meters.

3.
a check mark instead of color in checkbox control.

4.
position window near by mouse cursor.

5.
circle with degree input.

6.
insert vertex tooltip, select min. 2 points.

7.
mirror just the vertex points, example x=-x
(found plugin Coordinate Swap for AC3D)

8.
boolean, need a hint for correct normals.

9.
sweep around 90 arc, the angle should be parallel to circle
so the start and end will rotated correct.

10.
multiple boolean union, a list of objects meld together (batch processing)

Just a thought on Point #2:

1. Most programs seem to interpret AC3D's output in meters, and I work to scale in meters when I fiddle around with the program.

2. It is simple to work in whatever units you like in the program - you can use 1 unit as any measurement you prefer. As long as you know what your scaling factor is, you can size down or scale up the model to whatever unit you choose when it comes to the final model to be exported.

I'd like to add...

It would be nice to have a command that detects objects with no normals... sometimes even after optimizing, there are "bad geometry" artifacts leftover.

All surfaces have normals that are automatically calculated - it's not possible to not have normals. What you may be seeing is 2 vertex polygons, or other odd surfaces interfering with the normal calculations. Odd stuff should appear as red or cyan lines.



Probably best to use the menu Edit->Select-surfaces and then delete surfaces that you don't want.

"What you may be seeing is 2 vertex polygons." Ah, yes, that's it - I just didn't know what to call them.

Anyhow, those 2 vertex polygons are REALLY hard to find and delete, though, because they aren't showing as red or cyan lines. I have to select EVERY surface and hide it, until there's nothing left but the 2-vertex polygons, it's quite tedious and time-consuming.
A tool to automatically detect them would be great.

Did you try: Edit->Select-surfaces->invalid-poly?


Perhaps set all surfaces to be poly before selecting that?
