I sent you a PM so take a look at that. I expect on the wedge in my model you aren't clicking on a component when you move it. Instead of trying to tilt the component into position, draw it in place at the correct angle. I can show you that. As for making it easy to measure from it, when adjust the component axes correctly you'll be able to drag a copy out from the In Model components library and it'll sit flat on the ground plane.

Get another mouse for your laptop. One laptop friendly mouse is the Logitech VX Nano cordless laser mouse http://www.logitech.com/index.cfm/mice_pointers/mice/devices/3271&cl=us,en. On the downside, it needs batteries and forward/back buttons work with the index finger instead of the thumb. On the plus side is the stubby USB dongle, small size, and the Set Point software to control its features. You can assign SU keyboard shortcuts to its programmable buttons. The software even has a plugin http://www.mstarmetro.net/users/rlowens/uberOptions/ for more control options. I have the MX Revolution pictured in the uberOptions page. It's larger than the Nano and has rechargeable batteries. Sales and rebates can knock down the price 20-30 USD on both.
