Zooming In Close Up

[garystan]

Hi everybody :

              I'm currently using Sketchup 8.  And a weird effect popped up when I zoom in close to my project.  When I zoomed in,  I could see a cross section of walls and windows. But, when I zoomed back to a wide view, everything looked "normal".  
                                                             garystan

This is the well-known "clipping" effect. Most often occurs when your model is located far from the SU origin. Also occurs more frequently if you are not in perspective mode.

Bob James :
Thanks for your reply. I sort of understand what your saying. But in a way I don't. Two things I'm not clear on.........1)Being too far the the SU origin. And 2) Perspective Mode ?
Thanks

1) Being too far the SU origin.
The SU origin is where the red/green/blue axes meet. If your model is very far from this location you will often get clipping. These axes can be turned on/off under the menu View/Axes

2) Perspective Mode
There are three camera viewing modes (See menu Camera):

1. Parallel Projection
2. Perspective
3. Two-Point Perspective

You can often escape clipping (temporarily) by switching to a different viewing mode

to neutralize clippping bug:

1. switch to parallel view
2. do zoom extends
3. scroll mouse wheel 'till desired.

The cause of this clipping- you've got some objects (or whole model itself) placed too distantly from origin.
