I also need DXF for CNC milling.

@joergber said:

I did this because I use the DXF with heekscnc to generate milling operations (G-Code).
Milling a circle or an arc is much faster than several lines ...

Thanks for the plugin!
I also use SketchUp to create files for CNC cutting.
There is an excellent plugin to do the right Gcode in Sketchup, Phlatscript (SketchUcam)

You misunderstood me...

Ok!
What you said makes sense.
This laptop is new and has already come configured as the manufacturer, will change the user name.
Thanks for everything ...

I discovered what may be causing the problem

I put the file "quadrado.bmp" at the root of / / and it worked.

Thus probably a plugin or library has problems with Win7 versions in other languages (not find the BMP)

Thanks for the help

I can see a problem - accented-characters in file-paths can cause problems in some Ruby functions - like File reading and checking.
When you moved the bitmap file to C:/quadrado.bmp it worked because there were no accents in the path, BUT Usu**á**rio [your name!] has the accent in the path to the file on your Desktop!
Try renaming your account to Usu**a**rio and it should then work!
So the lesson is avoid accented-characters in folder-names and file-names that might be needed in Ruby code...

These folder names are standard Windows version in Portuguese, rename it can cause problems in other software

Probably, other users have the same problem and without discovering the cause, leave this excellent plugin, at least if they read these posts will know why.

Thank you, hugs ...

If you type [or copy+paste] this
TT::Plugins::BitmapToMesh.bitmap_to_mesh_tool()

• <enter> in the Ruby Console what happens ?:

He opens the window to call the bimap,
made the selection BMP + enter​​,
window appears after the figure:

That folder us called TT_Lib2 and it goes into the Plugins folder. It should contain lots of files and some subfolders inside it after the extraction, just as they are in the zip file when you view its contents...

I know the plugin and its installation.; Used often
Everything is correct, the files are all present, but for some reason does not work.

tested with various BMP 100x100 pixels.

It does not work, nothing happens.

Test File (bimap)
quadrado.bmp

Could you post a screen shot of the plugins folder showing the files?

I've downloaded and
put the two files in the folder plugin (SU)

does not work (in SU7 and SU8)

I've downloaded tt_bitmap2mesh and TT_Lib2 - 2.5.8 (also tested TT_Lib)
put the 2 files in the folder plugin

does not work (in SU7 and SU8)

I've used this plugin often with WinXP on the old PC, I am now using Win7 64

Thanks a solution.

The biggest limitation is that SketchUp does not have true arcs or circles. Everything is exported as line segments, and unless you used a lot of them, the segments could be visible on the finished part. Of course, this does depend on other factors such as the radius of the curve and precision of the machine. A small radius will probably not have visible segments, for example.

The shop is going to take the .dxf and generate gcode to run on the cutting machine. The gcode ironically does support true arcs, but again Sketchup exports only line segments so that is what the machine will cut. The more segments you model with, the smoother the finished part.

CNC machines and 3d printing have become affordable at a hobbyists budget. It's really too bad because Sketchup seems like a perfect fit otherwise, but this lack of curves makes it hard to recommend Sketchup for applications like cnc and 3d printing.

Wrong!

The plugin Phlatscript (sketchup to gcode) can transform the segments of an arc in instructions that specify a radius in the gcode.
