Zooming then model disapears
-
I have imported a simple acad plan. Then redrew over the plan to make a SU face (a few faces actualy).
Now I want to start to model the walls etc but when I zoom into the window, the model sort of clips and disapears.
I looked at the Model info and saw that it seemed very big, so i deleted the Cad layers which reduced line count from 14000 to about 152- but still clips and disapears when zooming.
Any tips would calmm my stress in the office.

syburn,
you seem to have some cad stray pieces in there somewhere, and you are at a very small scale.
I would open a fresh SU file, window copy to clipboard a very tight box around your floor plan get just what is necessary from as close as possible: Past it to the new open file, and rescale the drawing. Use 1:1 size on your floor plan. If your copy paste reacts the same way in the new file, do it again a little differently, you probably grabbed the troublesome cad floater!
hope this helps,

Hi syburn,
First erase the construction lines then if you do a "select all", you will notice a little line far from your model, erase it and everything will work fine;
Hope that help,

Woop, sorry i attached the wrong file, here comes the corrected one!

That still clips Elmer.
What Elmer says though is correct and is normally what may cause this. I just use Zoom Extents to see where the offending extras are.Another problem is you are so far away from 0,0.
I also noice you have extra lines on your imported drawing which should not be there. It is also not on the ground plane.
I would suggest making sure it is cleaned up corrctly before importing from ACAD.
Try the Flatten command, Overkill, Purge and Audit.Make sure you import at correct units/scale also.
Go back to acad, get rid of all the extra lines and text etc, place all remaining on 0 and run the commands I mentioned. Hopefully this may improve things.

I find that i have to import Cad files in mm or scale them up once imported. SU does have a small enough incrament for working in metres
What i mean is 1 unit = 1 millimetre as apposed to 1 unit = 1 metre
Hope i haven't confused you too much

I did draw to scale in mm, but when i imported it the dimensions all seemed wrong (so i used tape measure to change model scale).
Anyway i ll try all your tips now as see what happens.

What is the way to look/see find these stray cad pieces?

I say that because the dispaly all made your drawing very samll on the screen. I didnt see them, but elmer did, Your drawing was really unco-operative, so I opened a new session and copy/paste the plan to a new session and it corrected itself. You were right, about the tape measure, I work in imperial, but slect two points, tell the system what you want it to represent and select yes.
import your cad file to another file, it willcome in as a componenet, leave it as a component, if it disappears when you do a zoom extents your text, dimensions or something is messing with you. If it comes in ok trace over and around it and watch this video: Working with CAD:

Here is an image to show where that little line is.

oh thanks everybody, i understand now and managed to import again from a block (im using autocad LT 2006 and seemed not to let me purge or overkill or flatten so a block seemed to work ok).
I have developed the whole thing now and I have posted it in the rendering gallery. Not so happy with it though.
