Hello friends! I've a problem, as the title says, I can not offset some entities, even if they're polylines, at first they were splines, In other post i found that to "convert" them I needed to export them with dxf version 12, I did it and it works, it just add a lot of new points or vertex..  The problem with the offset is that if I put a value, for example 0.2 it doesn't work, but with a bigger value for example, 0.4, 1.0 and so.. it works good. there is another workflow or a solution to my problems? what I'm doing wrong?

Even if i open a dwg made in another software.. (illustrator) it doesnt give me the option to offset that entity, it recognize it as a spline. And I can't do what I want! Please help me! thanks!

Sal.

edit.

I notice that some splines actually let me offset them. but others no, they are closed, were made in the same program, at the end is just the same! what happens?
