Hello @alexkskim1 Here, the numbers are one way or the other - they -so far- do not flip in the middle of the edge… However, the direction does currently depend upon the surface direction - I can see that it’s probably OK to ignore this and use the World XY plane - I made it use the surface so that it would work with surfaces in any orientation, not just on the XY plane, but perhaps that is not necessary
At any rate - for now, use the
Dir (Analyze menu > Direction) or
ShowDir commands to make sure the surface UV directions correspond to the ‘Right hand rule’ (this is the natural UV and Normal direction of the surface).
U = X. V = Y, Normal = Z
It is one step more complicated on Rhino surfaces because the normal can be flipped - but for now ignore the normal (white) arrow- what counts are the U and V, the natural normal is determined by these. As far as I can see all the text comes out correct if the surfaces’ natural normal is up. I’ll see if I can make this easier,
Good, natural normal is up:
Bad, natural normal is down:
As for the script error- that is my fault - sorry! I was experimenting with adding actual text and I left one line still active - the script is updated.
