Can you crop image in Archicad? What I usually do is create a fill with
a solid background that would hide the other parts of the image I don't
want to show.
use this method then once you have created your morph element you can
press and hold CTRL+SHIFT then click and delete the solid face of the
morph to retain the morph lines only.
I agree with you on this one. For me I have used LPM for mainly doing
custom doors and windows that I want to be included in my door and
window schedule, like @Marc H said yes the objects there are fixed size
and not interactive as what we usually us...
