Accuracy

[j2sip]

Hi,

A newbie here. I have not yet done any intensive reading about sketchup but I want to ask a question. Are the output of those free curve/bezier plug ins suitable for CNC machining? I plan to draw 2d drawings of guitars and convert them to DXF and g-code.

Thanks in advance.

You will need to use a lot of segments in tour curves to produce 'smoothness' - as Sketchup makes curves of of short lengths of edges.
Sketchup's Arcs/Circles can have their segmentation adjusted prior to extruding into 3d forms.
The Bezier-tools lets you change the segmentation of other 'un-extruded' types of curves too.
If you export as say a 3d DXF then Arcs/Circles will become true CAD Arc/Circles rather than segments, but not so other curve types that are made of 'lines'...
But note that a 2d DXF treats all curve types as collections of lines.
If you are not planning to extrude into 3d etc... then why not look at one of the free CAD tools [like DraftSight2d or FreeCAD] that have things like true spline tools etc built-in...
