Odd View??

Hey guys, I create some 3d structure drawing and rotate it around. Just wondering, as you seen in the picture below, the farthest end look bigger than the closer end? why is that happened and how to set it normal (the farther end smaller, closer end bigger).

here's another pic

That's what happens when you use 3D orbit. Have you tried viewing your model in perspective projection? Even that has its quirks. If the camera is placed too close to the object the perspective will be distorted. Too far away and the effects of perspective may be bearly noticeable.

I stick with the traditional isometric views in my drawings. Typically, these are included to give an overall view of the object (more like just a pretty picture). If I were working in the architectural field I think I would be more concerned.

how to get perspective projection?

Type PERSPECTIVE at the command line and change the setting to 1.

thanks, i'll give a try. btw, just bought logitech trackman marble mouse about hour ago, try it on acad program, it's great. only drawback is no scroll for zoom, I wish they have trackman wheel but they don't...

cad64, thanks for your tips, that's really work. thanks again.
