My process of modeling thus far is to:
Generate a set of guide lines for each principle ortho view.
Project each set to its relevant cplane to make certain all is planar
Make certain they align properly to each other.
Those guide sets are then placed on separate locked layers.
Using the snap to locked objects setting, I then create the curves I need.
I often project those newly created curves to the cplane as well.
Once those are made I use the gumball to drag a number of duplicates.
( I would just as soon use the move tool, but I don’t know how to make a duplicate while doing so - tapping the option key doesn’t work.)
The other way is to copy and paste a duplicate and then use the move tool but that’s the sort of extra clicking I try to avoid.
Its at this point things get silly. I’m assuming that a duplicate curve moved orthogonally will have its end points remain orthogonal to the original so that a straight line drawn orthagonally from any point will be intersect at the same point on the copy.
This does not always happen however.
This is why I’m getting out of sorts. I’m not sure how to set up the program to draw with confidence.
(ie- select all then run Intersect ) Thanks Jeff, that’s another powerful tip.
