Importing SVG: // Error: Unexpected number of points for SVG path.

warpcat — Mon, 21 Dec 2015 03:54:33 GMT

I've just started importing svg files from Inkscape: I can make as many simple squares as I want, and they'll import just fine. But if I do anything remotely more complex, like a simple scribble with the calligraphic brush (with say 10 points total), or a simply polygon with the freehand tool, I get this error on import:

// Error: Unexpected number of points for SVG path.

Something seems seriously amiss. Any thoughts? I've attached a simple 5-sided polygon that gives me this error.

FWIW, I tried your file in Ext1 Sp5 and got the same result. Not sure what's going on there, but I find error messages like that quite entertaining. It makes you want to ask "Well, how many points were you expecting?"

(I actually got an error message while doing something else today that said "This shouldn't happen." I have no idea what that was about, and it didn't seem to cause a problem.)

I agree: I wish it said how many points it was expecting. Right now the feature seems useless, unless I want to make everything out of squares 😞

Autodesk, you there?

It appears there is zero traction on this, but doing a bit more digging, it appears that it's the svgToPoly node itself that is failing. Running this mel will trigger it when pointing to an 'invalid' svg:

setAttr svg1.svgFilepath -type "string" "c:/path/to/my/file.svg"

I've done tests: Simple primitive circles and squares will read in fine, any numer of them. But if I create a three point triangle with the pencil tool, it'll trigger this. Or making a hexagon primitive: Fail.

😞

I had the same problem which is how I found this thread.

I found that 'Importing' the .svg failed, but ctl-c'ing the shape in Illustrator and using the 'Paste' option in Maya worked.

Yuuup, hit the same problem. Dug around a bit and it seems like the SVG import only manages files that have straight lines in them. SVG uses commands like "M30,30" (moveTo x30,y30) and "v400" (vertical line from current point to +x400). Any time there is something like "c40,-30" that tells Maya to draw a curve it just results in

"Error: Unexpected number of points for SVG path." (Script Editor)

"API error detected in S:\Maya_2016_DI\src\Maya\src\Type\svgNode.cpp at line 218

: (kFailure): Unexpected Internal Failure" (Output Window)

I attached a couple of example files, 410.svg should work and asd.svg should fail

Illustrator import seems to work fine though, using that as a workaround as well.

I was excited for a smooth 2D vector --> 3D workflow, this is a bit of a joykill 😕

Fix: use Inkscape, Path => Union

@Anonymous : That seems to work, thanks for the tip.

I'm getting this same issue saving an SVG from illustrator. Using the inkscape trick doesn't appear to work I still get the same error message. It's just a simple shape and text from illustrator.

Is there some SVG export settings that has to be set for the importer to work in maya? This is really frustrating...

Make sure that you have the path selected first :

'Edit Paths By Nodes' tool [F2] > select path

Then Path > Union

Save as plain SVG

@Anonymous Thank you for posting this workaround.

Make sure you first, make outlines of every single object in illustrator and then save it as a plain SVG 1.1 - then it works
