Here's how this started..
I made this sketch in illustrator (which im not really familiar with) and exported it as a dxf file and then imported it in a sketch..
As you can see, the outlines of the triangles from the dxf are overlapping.. so what I need to do is to find an outlining curve or maybe an intersection curve between the curves to enclose the overlapping areas.
I want to do that in order to extrude the sketch to look like the picture attached..
Finally I've included the illustrator file as well just in case it's of any use.
Thanks in advance ^_^
