Partial drawing
In AutoCAD 2009 you may run across what I term is a ‘bug’ when it comes to partial drawings. I have had an issue when starting a new drawing that it will actually start as a partial drawing. This can become annoying, especially if you have any customizations that may be dealing with layers. What is even more amazing to me is that this ‘bug’ has not been caught in any of the service packs.
In a nut shell, AutoCAD has a new variable - openpartial which is defaulted to 1 which allows you the ability to open a drawing in partial open. It is my feeling that when you are starting a new drawing, you should not have to be concerned that it has a ‘bug’, especially an inconsistent one that does not ‘show up’ all of the time. Therefore, in order to alleviate the worry of a ‘bug’, the very first thing that should be done is to change the variable to 0.
Partial open is suppose to work when the drawing is saved in paper space and the variable INDEXCTL is set to non 0.
The following are the definitions for these two variables:openpartial - Two conditions must be met for this system variable to have an effect. The drawing must have been saved with paper space displayed (TILEMODE is set to 0), and the INDEXCTL system variable must be set to a non-zero value.
Indexctl - To receive the maximum benefit of demand loading, it is recommended that you save any drawings that are used as xrefs with layer and spatial indexes.
The point I wanted to emphasize in this blog is if you do use partial open drawings, you need to be aware that your new drawings may start off with the ‘bug’ described earlier and you need to deal with it. If you do not use partial open, set both variables to 0.
