Hello everybody, I want to buy the new version of sketchup pro 2017 to make metal parts to be cut on a CNC plasma cutting machine (works in 2D). I noticed that sketchup draws circles, rays, rounded, curves in series of lines and not in points, can you tell me if it is possible to preconfigure sket…

Someone better will come along soon but I have gone through a bit of a learning curve on this topic myself. As you start to strike an object or (after you click the first point) then tap the tab key and type a number then lower case s eg- TAB-> 100s {enter} That will create your circle/arc with…

I find it better to use a number divisible by 12. That means it is divisible by 2, 3 and 4. @ENP , what file type are you exporting?

The answer has not changed in SU 2017 from earlier versions. If you export as a 2D graphic to dxf, you will get the segmented representation of arcs and circles because that export is geared to be a WYSIWYG snapshot of the current view, which is affected by the segmented representation. If you exp…

Hello, With my friend who tries to convince me to spend a sketchup, I just try a 3D export DXF of a circle, you are right, the circle is exported correctly, and the quality of the lines is clearly superior, thanks for Information. After several tests I find that the problem is that: If I draw a s…

To show you, here is a test with empty surface, and volume not extruded.(export: 3D DXF) [image] [image] You notice that the drawing does not match

It would be very simple to write a short ruby that would erase all faces in a model. perhaps one of the gurus can post one (I’m traveling without my computer for a few days or I’d do it)

Here is a test in export 2D 24 segments [image] [image]

Strangely, without having changed the number of segments, (24) the circle would appear correct except on the bottom right of it, or it makes big segments.

By increasing the number of segments, it will reduce the size of the segments, but they will still be (in much smaller) but will create a fault mark in the part when cutting.
