I want to measure the distance from point a to point b in the PCB editor. However point b is surrounded by pads and primitives, thus when I try to move my cursor to point b, the cursor keeps snapping to the pads and primitives. Under normal circumstances I love this snapping feature, but sometimes I require a specific measurement that the snapping feature prevents me from doing.
Is there a method to quickly switch between snapping and non-snapping when using the "Measurement Distance" tool?
Press '3' to enter 3D view mode. Tools->3D Body Placement->Measure
You are then prompted to select your points (message appears at the bottom of the screen in the bar with x/y coordinates).
You can measure points on the same object or between two different objects.
It sounds like your vertical component clearance is set to infinite, or at least a ridiculous number. I generally set mine to 0mm unless a specific application requires that I change it. You can modify this value in the Design -> Rules window (shortcut D-R), down near the bottom under "Placement". Look for "Component Clearance" and set the "Minimum Vertical Clearance" to 0mm. If the radio button to the left is set to "Infinite" you'll have to change it to "Specified" before adjusting the number. See if that helps.

Hold down the Control key to temporarily turn off snapping. Release the Control key to go back to snapping.
