I have been struggling with top down layout design. I have a top and right side layout sketches that define my basic building blocks. When I enter layout mode I am on the front plane. I double click the Top plane and sketch a rectangle in the TOP plane. I make a block from the rectangle and then a part from the new block. The constraints say that the line segments are on -on-plane. When I modify the new part and project my sketch to create the slab, the sketch flips to the front plane and projects at a right angle to my intended direction. The sketch now appears on the front plane not on the top plane where I defined it.
The other thing I notice, is that the red origin markers are not pointing to the right and to the top as I expect in a new sketch. How do I make sure I am sketching on the correct plane? Why does it flip to the front? I click normal-to and I am viewing the top plane from above. It all seems correct. I got most of the layout done correctly but I still have strange things happen where blocks flip direction and orientation. I am going nuts with this Top down layout mode that seems so elegant in the demonstrations.
I will attach. Plate-2 is the sketch block I want to project.
