I am new to the community, have used Sketchup for a few years and am proficient enough to support my students to build fairly complex architectural models.
My issue is that we always fail to export a flat dxf file to our other CAD program for laser cutting. We nearly make it, the file is almost correct but normally is not dimensionally accurate, loses some information or appears skewed, even when centred on the origin, presented in south view and using parallel projection.
I have followed internet advice previousley and have tried repeatedly but we never get a faithful version.
My current process is: Create simple shape or copy simple face from more complex model. Centre face on origin. Set to south view. Parallel projection. Export DXF 2D. Change NO settings. Wait for download.
Okay, so this worked. BUT I have found very spradic success…
The same process this morning achieved 12 failures in a row. The circle you see here does not allow me to use the radius dimension tool on Techsoft though I think thats the way that Sketchup draws circles.
I will need to post again with the next failure to try and solve the problem, never has success actually been failure!
I had included the whole process in screen shots but am only allowed to post 1 image as a new user.
Thank you for your response, I will post the next failure here and try to work the problem.
I had success with the shape in your post, following exaclty your process, I tried a slightly more complex shape and partial success with correct dimension but a free hand line that did not transfer. I expect that shapes with standard geometry might fare better. I will keep trying more complex shapes, usually we would need to convert the side of a sketchup architectural drawing for laser cutting as a real world model.
Using the SU 2026 (desktop), you will be able to export Freehand lines. Currently, from the web version, you can also export Freehand lines if you explode them first.
