Possible future enhancements - reverse faces of left-handed helical ramp #29

Open johnwmcc opened 10 years ago

johnwmcc commented 10 years ago

The Helical Ramp shape drawn with negative pitch to produce a left-handed helix has back faces upwards. It could be more useful to have it with front faces upwards.

Could be coded EITHER by drawing mesh polygons the other way round (which I can see how to do), or by selecting all faces at the end, then applying .reverse! method. Unfortunately, I can't see yet how to select the faces from within the container.

It's easy to open the helical ramp component for editing, select all faces, then apply contest menu 'Reverse faces', so this may not be worth doing.

The best fix here would be to generate the faces with the correct order of the 3d points.

I'll try to do that, then. May be will take a few days, since I'm likely to be busy on other things for the next couple of days.

Now done. But can't generate pull request for latest update - see new issue
