Application - ADT2005 Computer - 2.52 GHz P4 w/1.5 GB ram
I haven't worked with standard AutoCAD 2005 but ADT 2005 calculates/populates/lists or whatever the correct term is, layer filters on the front end now (upon opening the file). When using Layer Manager, the left side of the dialog box shows all layer filters.
I received a simple enough civil drawing that is only 253 KB in size. Layer manage took an extremely long time to open (I have already installed "layer manager opens slowly" patch from Autodesk). I was surprised (shocked is probably a better description) to find 436 layer filters. The first question should probably be - where in the world did all those layer filters come from? Well, it seemed like the appropriate action would be to eliminate the filters. Bad idea! After about 15 minutes of waiting for them to go away, I thought better of the idea and stopped the process. Next, I ignored the layer filters and clicked on "select all" with the intent of thawing all the frozen layers. Terrible idea - this process brought my computer to a complete stand still. 20 minutes later, ctl-alt-del was my only choice.
Has anyone else experienced this? I can't help but to wonder what Autodesk was trying to accomplish by creating this behavior in layer manager. I have figured out a work-around which was to create an empty layer filter group file and load it into the drawing. Why do we have come up with creative ideas to get our program to work in a sensible manner? WTHK!
P.S. No, I didn't flunk English composition class ... which can't be proven by the preceding rambling.
