LDCad 1.7 Alpha 2 (win+linux)

[Roland Melkert]

And am I right about the different behavior in the Source window—if you Ins a meta (like a ROTSTEP) you'll get a new instance of that meta with the values unset? Or is that a different function that I just assigned the same hotkey to?

And by the way, since I don't have an Ins key, I re-mapped all of its functions to the space bar, which I really like and might even recommend to those who do have an Ins key. 

If the last used 'part' is a step meta, ins will insert a new one using it's default settings (just like normal parts except those also use the working color and orientation).

Any item available in the part bin can be used as the working part. This is a requirement of the internals, hence those awesome custom artwork items

The default space bar function is to zoom the last used view when using multiple views.

But if you don't need that it's a good alternative for ins.
