Floors in 8.0

[cek]

I recently converted a Revit 6.1 file to an 8.0 version and discovered that 8.0 does not like overly complex floors (slabs).

This particular project has a patterned hardscape of about 20,000 square feet. In 6.1 I tended to just edit the original slab so it got pretty large.

8.0 didn't lilke this floor so it would take 2 to 4 minutes to process each edit. Meaning a dragged line or end point, a deletion or any change to the slab perimeter. Each event was taking 2 to 4 minutes to process. Painfully slow!

8.0 also saw certain lines as essential to the slab and would not let me delete them, so I had to find a way to encorporate them into the perimeter. (This may have been an artifact of the conversion process).

My recommendation on how to avoid the long edit processing times is to break up your slabs along control joints. I noticed the smaller slabs processed much faster.

If I were faced with that issue, I would probably just go to a site plan view and isolate that one element, so that only it is visible, draw drafting lines around the entire perimiter using the pick tool (tab to select all edges), then delete the slab that was originally created in 6.1. Now create a new floor slab, and while in sketch mode, again use the pick tool to pick all your drafting lines, to create a new slab. Then when that is done, delete all the drafting lines. Try that and see if the performance is any better.

You can do this easier:
- Edit the slab, select all sketch curves.
- Ctrl-C
- Quit editing.
- Delete the slab.
- Create a new one and paste back (Same Place) the just copied curves to the sketch.
- Voila
