Something a lot of my clients have been seeing lately is trouble with switching between Model Tabs and Layout Tabs. This is an easy fix. Follow the steps to make life easier.
1. Set the WHIPTHREAD to 3, this SV controls whether to use an additional processor to improve the speed of operations such as zoom, redraw or regenerate the drawing.
One thing to keep in mind, when multithreaded processing is used for redraw operations (value 2 or 3), the order of objects specified with the DRAWORDER command is not guaranteed to be preserved for display “but is preserved for plotting”.
This option regenerates the drawing the first time you switch to each tab, the display list is saved and regeneration is suppress when going back and forward between them…
I hope this tip helps. Having any Civil 3D troubles? Let us know and we will create a tip around it.
