anyone share with me
There is something you can do. Maybe upgrading Planswift to 64-bit would make a world of difference. Even with a 16 gig ram machine, when drawing rafters on pitch with more than 4-5 planes, it can take one minute or more to populate my list. This with no other digitizers open. I also transfer all my .pdf files to .tiff.
Here's my tricks;
Do not generate Labels. Turning on the rafter length labels contributes to slow downs.
think about the number of Sections you use. If you draw a large roof with one Section PS will generate all the rafters within that Section, if you draw a large roof in multiple Sections PS will generate only the rafters within a Specific Section at a time. If you need to clear rafter and redraw a Section or make changes PS wont have to redraw the whole page but only the Section effected.
