Uh, Rastamant, just to be sure that I do everything correctly :
I load my tool with the topology in progress.
I don’t draw it on canevas or anything.
I press the CLONE button, just under Import in the TOOL menu.
I draw my cloned tool on the canevas, press T (edit) and now I should be able to see the topology I create and not only the one that was previously done.
Is that correct ? because if it is, it doesn’t work :S
