Problem in general with the Blend function arrives with these Side 1 and Side 2 !

Blend works in this case only if Side 1 and Side 2 are both "Edges" of the surfaces (here the rectangle and the recessed surface) and not any curves of construction!
A little trick is to read on the Info box up right corner when you select them!
if it's "Edge(s)" it's OK, if it's "Curve(s)" Blend will make nothing!

So delete or hide these "curves" of construction!


And Blend will works at each time! ;)

Fixed... Merci Pilou. :-)

Hay people,
Looks like nobody here showed this method yet, much faster and simpler:

Very convincing!

Very nice Andrei but I don't understand how in 0:50 of the video you condense/simplify the points of the cut surface so that you can later move them. Is it a command that you're typing ? if so which one is it?

Niko, use this command to shrink surface: ShrinkTrimmedSrf

Press Tab and write ShifrinkTrimmedSrf you don't want add a new shotcut!

Thanks guys...thats a very powerful command...I think Michael should somehow stick it in the UI

I can imagine dreaming up icons that represent some of these commands would leave Michael with a serious migraine, so perhaps we could convince him to just create a single icon of a treasure chest (or toy box?) that opens a list of the many many scripts and commands available but easily forgotten. At least easily forgotten by folks like me who only get back to the program periodically.

I agree.

I do believe Michael has that idea on the list.

me too :)
