<< is wrong...

I don't know, less easy surely! :)

here for remplace the Offset maybe the Edit Frame can also works?

Hi Pilou,

load for example Torolf's image into MoI, which Pierre has posted, and redraw some cells with polylines. Then use your method were you showed to click on point 1 and 2. You will see that the closed line will not match. Now do the same with clicking in each corner of a cell and you will have the same closed line(s) as Torolf shows. :-)

BTW. i overlaid your right example with the left example in Photoshop and there is also a difference... :-)

Best regards
Stefan

Yep you right, there is a very little difference for the triangle!
And if you have more than 3 vertex the method of conics seems out the subject! :)

Hello,

maybe it is possible to split or trim a backround face by the structure. Then select the edges of each patch (maybe script?) and join them. After that you can reconstruct the edgeloop by controlpoints (reconstruct script). The facepatch schould have a centerpoint which can be selected for scaling. Sorry, but I don't have moi at the Moment, to test it. So it's only an idea.

Kind regards
Karsten
