Thanks for the "use a 2d program" tips. Helpful.
Parallel projection and standard views don't seem to help.
Here's an example. I'm laying out a picnic setting. Ground area done. Tree in the middle done. Table built. Trying to move the table towards the tree. Top view. I can select and move the table, but Sketchup assumes I wish to raise it off the ground and connect it to a branch of the tree.
I have NO wish to move it towards me (away from the ground) or away from me (towards the centre of the earth), I just want to move it north, south, east or west, so I can position it, rotate the model, look at it from different angles, move it again etc.
I could hide the tree, but then I can't see the tree.
This would be SO EASY if Sketchup could limit itself to working in the only two dimensions I can work in!
