Background:It can sometimes be hard to place a camera in a confined space or in very complex models. This "How To" will give you a couple of good tricks to easier place a camera in a 3D model.
Step 1: Make sure that all ACS Lock are or any other Locks are not activated.
Step 2: Draw a help line in the position where you would like to place the camera, this makes it easier to place the camera in the desired position and height.
Step 3: If needed, rotate AccuDraw to Top and lock the Z-axis to insure that the camera looks straight ahead, unless the camera needs to look up or down in elevation.
