I discovered that my code was using the screen zoom in one of the DXF export calculations, and that the math used to guess at a good connector radius was not quite right. After fixing those two issues, I also made a change to improve the solid link shapes, and I think that I have it right.
Linkage Solid Link
DXF File Solid Link
The connector size is calculated to be a proportion of the overall mechanism size. That’s very different from the screen image which uses a fixed size for the connectors regardless of the mechanism size. The screen connector size is always the same even when zooming in and out.
Anyhow, there is a new Linkage program available here. This has these DXF export improvements.
Hi Dave, congrats for your sw! I’m not a mechanic engineer, i’m just a 3d modeler, but I’d like to try to use your sw to build a sort of “toy” for my coming baby…so I’m trying to export in dxf mine mechanims, but the dxf export always file, I have always the error message “this feature is not complete …..” even in version 3.7.5, can you help me? thanks in advance, hope to hear you soon!
The message is a warning because I wasn’t able to get everything in the DXF file exported correctly. Click “OK” and then go ahead and select a file and export the mechanism. I don’t recall what is missing in the DXF file but a quick test with the Jansen leg mecahnism worked fine. I will do a bigger test and post the results.
