Anyone? I'm new to Inkscape but have very high expectations, cause of the art work I have seen all over the web, and want to master this app, but got stuck. I'm figuring out how to use the whirl effect, but I don't get it to work.
I read the tutorial, but is very brief. I tried it with a simple object whicg I converted to a path. Then I aligned it to the center page and selected Effects > Modify path > Whirl... but nothing, what am I missing?

Thanks in advance

Ok, I solved the problem. I just closed Inkscape entirely and restarted the app. Did the same steps and it worked just fine.
