Dwg dxf and 3ds model face lost
-
Hi eweryone.
I have a problem with some models, which I donload from internet, they loose faces and there is only edges. Can someone help me with that, maby there is some bug to be fixed or the file is damaged or some plugin is to bee needed that can make several faces between several edges.

Thanx -
On first glance, this image suggests the Clipping Problem. There may be other issues such as non coplanar edges and such. Here is a link that may be helpful on Clipping: http://support.google.com/sketchup/bin/answer.py?hl=en&answer=36261
There appears to be no permanent cure for insufficiently prepared source material.

No I know this problem but it isn't so.
thanx anyway -
Perhaps you could post the SKP file so we can see it?

[off:lllwau7f][/off:lllwau7f]Off topic, but related. I do not like how imageshack pops stuff up and refuses to allow me to use the back arrow to return to pages. I know I can add a tab at the top to view the link.

[off:1kerhvd6]I also dislike Image Shack and have learned to ignore links to images placed there.[/off:1kerhvd6]

The SKP would help get a resolution.
there's no need to post files of modest size remotely - you can easily attach many file types to your posts [zip others]...
In the meanwhile...
if it's definitely not a Clipping-Plane issue, then how about a Graphics-Card issue ? -
Any spec of your machine ???
It doesn't look like a Clipping problem...I had a similar effect when my object was very, very small...
I couldn't close/draw some of the facesCan you scale the object x100 or x1000 and move as close as possible to the origin point - see what happens...

If you are importing these from other file types make sure you get the options 'units' set right.
For example, importing in 'mm' when the original file is in 'm' will make the SKP model 1/1000 its proper size - Sketchup/OpenGL can't create very tiny facets, so some bits might be 'lost' in translation.
Similarly importing in 'm' when it's originally in 'mm' can have the equivalent issue, with very enormous geometry failing to form too.Assuming the Units size is correct...
The clipping-plane issue can also results from having geometry that is far away from the model's origin.
Importing a DWG/DXF and 'keeping the origin' in the import-options can put the imported objects miles from the origin, then OpenGL can fail to render it properly.
Even if you import CAD data ignoring the CAD-origin then it can still have issues.
For example, if a 'Block' has been made in the CAD file it is imported as a 'Component' in the SKP.
That Component's origin is the same as the Block's.
Some sloppy CAD users make blocks in their files with the geometry miles from [0,0,0], BUT accept [0,0,0] as the Block's origin.
Therefore although the Component's geometry appears near the SKP origin its insertion-point id miles away - this has the same clipping-plane effect since the bounds of the model are unnecessarily enlarged.
Zoom Extents will show weird model bounds issues.
This can be resolved by using Model Info > Components > Show axes ON.
You might see axes-markers miles away from the origin...
Select an imported Component-instance, right-click context-menu and use 'Change Axes', pick a new logical insertion point for the axes, probably on the object's geometry corner etc.
Changing the insertion point does not shift existing instances, but new ones will now attach to the cursor sensibly as you place them...
Recheck with Zoom Extents and/or the clipping-plane issue... if it still exists try changing the axes of other components until all are sensibly located and the issue is abated.
