Ha Dennis thank you very much for your help.
There are indeed cases where it's a little more complicated than just a few adjacent quads ...
I think this tool should work with at least 2 contiguous surfaces selected (to have the direction of the slice process), and only if these surfaces are quads (?).
Some pics here too :
Selecting contiguous surfaces :
And then the result after the tool has been applied :
Do you think it would not be possible to insert a vertex at A and B ?
If both beginning and end selected surfaces are contiguous, I suppose we will have an "unwanted" vertex. I don't know if the plugin would delete it or if we would have to do that ourselves.
Here's a picture of selected surfaces which could maybe cause a trouble (??) :
Again Dennis, thanks for your help.
I keep reading this topic for more.
Ho and Andy, thanks for the free update (for users who purchased after November 2004), very appreciated.
