I still have frustration with this seemingly simple task of making co-planar geometry
Im just trying to draw on existing faces and push pull to create openings, in simplified building model , for purpose of 3d printing.
One reason why its difficult with this model is that there are some walls off axis
and im trying to trace of other layer that may have slight differences in wall position
Usually i will persist with a variety of methods, and get there
some ways to fix-
retrace line by line
draw triangle all over the place
try to see if line not quite on face by zooming in then try to draw perpendicular toward face
align axis with bit i’m working on
intersect with selection or model
draw face purposely away from wall then push right through / then intersect
drape onto face
I should try solid tools more often
in this case at the moment i feel i have to start again with some walls ,that were drawn off-axis.
Intersect with model is not working for me now as other geometry on other layer / group
Maybe best separate into groups at start of project with each group aligned to on axis.
Then make hole, then join group together.
I do have lots of plug-in in my armory from the wonderful developers on these forum !!, there may well be some great solutions out there, Until I used this forum i never new why some lines are thinker than others !!! (thin lines intersect face - whereas thick do not)
