LDCad 1.7 Alpha 1 (win+linux)

[Jaco van der Molen]

His most recent post here was a year and some days ago, and the most recent updates to LPub3D appear to have been the October before that (2020).

Indeed. I was helping him test the buildmod feature, but suddenly all went silence.
It was (is) a very promising feature and we got things to work quite nice.
Still a few bugs here and there though.

I have tried to contact him, but he is not responding to e-mail, PM or Github messages.
I sincerly hope he is allright.
