Draw Curve Tool

[TomRaynor]

The Draw Curve tool on the shelf has the following code in it:

 

 

"""

 

import stroketoolutils

kwargs['type'] = "curve"
stroketoolutils.strokeSource(kwargs)

 

"""

 

 

I was wondering if there is any way for me to be able to grab the geometry node that gets created when this tool is run and store it in a variable?

I tried modifying the line:

 

stroketoolutils.strokeSource(kwargs)

 

to read:

curve = stroketoolutils.strokeSource(kwargs)

 

but curve returns None.

 

Any suggestions?

Thanks.

Try just using the last selected node.

Yeah that was a bit silly of me. Shoulda thought of that, thanks Edward.

 

I was making a little shelf tool to be able to sketch out curves that have a uniform divisions, tangent vectors and a parametric 0-1 value per curve.

Might be useful to someone, see code below. Thanks again.
