- You can just enter 3d coordinates for the point not on the Word xy plane since osnapz won't override keyed values. This works for lines, not for rectangles. For 2d polylines to work, you need to change the UCS.
- If you're just using object snap, while picking points, make sure osnapz is set to 0.
- If you switch to a non-plan view such as an isometric and then turn ortho on, you can mouse pick a vertical line as long as osnap isn't involved. It won't be overriden by osnapz.
- If you use point filters, you can temporarily override osnapz by using either .xy before picking the point off the xy plane. Then you will be prompted by z. You would need to key in the z coordinate unless osnapz is set to 0.
- If you want to work in multiple orthographic planes, either
- Set ucsfollow to 1 and use the ucs command to change both the view and the coordinate system
- Setucsortho to 1 and use the viewport menu to choose the orthogonal view you want to work in.
Most people like not having linework off plane in ACA since the AEC elements have multiple view representations and most things are simpler without non World 2d geometry involved.
