How may I eliminate splines from paths that I have created from text using Object to path? What I have done is:

1 Enter a text character having only straight edges
2 Done "Object to path" - result on left here:
[EDITed to show spline control points]

3 Save as .DXF

Hoped for: DXF containing only LINE entities - as required the the device I'm driving.
Observed: DXF containing SPLINE entities - here http://pastebin.com/twK124sg

The right-side character was created with the SHIFT+F6 tool and does not show this problem. Simplify (CTRL+L) does not solve the problem.

Any help greatly appreciated.

Welcome to InkscapeForum!

In the Desktop Cutting Plotter dialog, that should come up when you Save As DXF, did you have "Use LWPOLYLINE type of line output" checked, or "Use ROBO-Master type of spline output" checked. I'm guessing you should use the first one (which is actually the 2nd one on the dialog).

Although, I don't understand what I'm looking at, when I follow your link, so possibly I don't understand the problem.

Thanks, Brynn.

Thanks, but I have tried both and neither solves the problem.

The best workaround I have used is to eliminate curves before Save by applying Extensions, Flatten Beziers. Taking care not to let the numeric control go down to zero, since this here causes app hang.

You have the right idea but instead of using an extension whose purpose is to REDUCE curves, you should eliminate all spline info by selecting all objects, switching to the nodetool, selecting all nodes, and clicking the button in the nodetool control bar that says, "make selected segments lines".



Does this work?

Yes thanks. it does work in the letter A example.

But now additionally I have fuller curves such as in letter O and so have the genuine requirement to reduce curves to line segment approximations. Hence it looks like I'll be using the extension solution for both.

Thanks again for the suggestion.
