Hi,
Does it occur to you that AutoCAD cannot handle that much data?
A quick measurement I did indicated that AutoCAD uses approx 29.2Mb for 1Mb
of points
At 50Mb of Points you would be looking at a drawing size of about 1460Mb.
I initially limited my drawing to 1,050,000 points (31.3Mb) and at that
stage free memory as reported by the Status command was 979Mb, ie with only
1Gb RAM the computer would already be using the Windows swap file.
A single "Zoom Extents" reduced free memory to 776Mb
The drawing at this stage was already unpleasant in terms of response times
and crashed when I tried to copy all the points to make it 2,100,000 points
in the drawing.
After re-opening the drawing I added another 500,000 points and the drawing
size extended to 45.8Mb and free memory reduced from 976Mb to 779Mb. Based
on this information it appears I would run out of memory at about 3,500,000
million points and a drawing size somewhere about 110Mb.
To work with your data, you are going to need to filter is down
significantly.
If you have Civil 3D R2007, keep your eye on www.civil3DTools.com
We will be posting a program there some time in the next couple of weeks to
filter this type of data. The program passed from Alpha to Beta yesterday
and now needs to go through quality control testing before posting.
