AI import creates "double splines"

Recommended Posts

I quite often use Illustrator (more Vector Magic these days) to get a spline of a logo to extrude.  What I often find though is that my splines contain multiple points on top of each other which can't be seen until I extrude, which obviously buggers up the geometry.

 

I can't find much information on this, and I wonder what I'm doing wrong.

 

I realise I could just trace the logo manually, but I'm useless with bezier splines, so it's often too time consuming.

Yeah I'd like to know that too. Now we have a spline pen that is arguably superior to Illustrator (and anything else) I find myself creating splines direct in Cinema these days, if I can, but occasionally the client will send through splines of their own which are almost always broken to some degree when I first get them. I don't know why this is, but they all seem to need some tidy-up or surplus points deletion ! However, you can usually see where the issue is at a glance by taking note of which parts of the splines are blue, and which are white.

Glad to know it's not just me.  When I extrude the spline, make it editable, them export to, say, RizomUV, it's completely b0rked, with all sorts of wonderful geometry.  If I go back to the original spline, select a point and move it, I discover that there's at least one more hidden behind it.

And while we're on the subject of splines in C4D...will they EVER introduce a way to constrain angles when creating them?!?

I think he means that it would be nice if we could hold a modifier key and constrain the spline pen to a preset angle when drawing the next point. I'm kinda with him on that one. It's the last bit of functionality that would make it the perfect tool... :)

I only recently discovered the lock tangent rotation, length etc in cinema, which made all the difference. Ya can't beat those little corner modifiers in illustrator tho, or that recent addition where you draw over shapes to merge them or cut them away from each other.

As what are you saving your file in illustrator? .ai version8? 

I second this. Illustrator 8 is the least problematic when importing Illustrator files. Though you should be doing some clean-up work on the splines first  -- depending on the design -- to simplify the linework for specific 3D purposes. For instance, the lines you would need to create an extruded logo spinning in space might be different than what I would need to create storefront signage that is internally lit.

Been there! One thing can help is when you import, uncheck the option for Connect Splines.
