i got a dwg with only one objectif i go into edit mode this object has around 2000 facesbut when i get back into object mode i see 20000 faces ?what’s going on therei did put a procedural texture - is it where the problem is ?can someone explain Tanks & Salutations
Does it have subsurf modifier on?
He said he brought it in as a DXF import @ 20k faces…
RJ, I don’t know, can you merge some of them into fake n-gons so object mode looks cleaner?
But that brings up an interesting observation; I take an icosphere 64/64 and subdivide it until it’s 5M faces and about a gig of RAM, and I can still manipulate it realtime in Object mode… because it’s still just a 64/64 icosphere.
Whereas if I do a plain subsurf on said sphere, the 5M face locations are exactly the same, but in object mode it takes a good 0.5 - 1 second to do anything to it. Tabbing out of Edit mode literally puts up a wait clock! (About 3 seconds.)
What controls the geometry culling for the on-screen display, and why does it work optimizing some objects but not others? Hmm.
Well, if you do a plain subsurf, you are adding faces that aren’t parallel to each other. When you just subdivide, you can look at it in object mode and see no difference. Hit slowerdraw, and you’ll probably see the same effect.

Where? I wasn’t sure if he said he had a dog (dwg).
If it is dense in object but not in edit, then it has to be subsurf (with it turned off for editmode). Everything else would be the other way around.
dwg =drawing and not import from DXF
i created the object from one cylinder and 2 - 1/2 sphere to make a tank
and then joint
–> Subserf 2 levels -->20 000 faces
–> 1 level --> 5 000 faces
Ok this does explain the faces
But i tough subsurf did not changed the object - that this affected only the render mode to give a higher quality of surface finish !
but it seems to also affect the object mode but not the edit mode !

Hey,
1 -> Toggles if it affects the object when rendering.
2- > Toggles if it affects the object when in object mode.
3-> Toggles if it affects the object when in edit mode.
4-> Subsurf levels.
Tanks very interesting
Suggestion
i hope this is explain in the wiki book if not may be you should include a new page to explain this in wiki book
loads of info on this page about the modifier including explaining all the buttons http://www.blender.org/cms/Modifier_System.681.0.html
and in the wiki http://mediawiki.blender.org/index.php/Manual/PartII/Modifiers
in wiki the subsurf page does not explain very well those 3 buttons
this page should include all the explanation but it’s not!
but it is in the modifier page !
don’t know why !
I thought he said DWG.
Anyhow, I noticed that when importing or opening DXF files, there are multiple occurances of duplicate vertices. Rem Double fixed that for me.
In My original drawing - i had over 1,000 000 faces
i needed 6 of theses fuel tanks + 2 other smaller one
you can imagine how slow it was
just moving the cursor took from 3 to 5 seconds
this was unreal
Conclusion:
So use subsurf with caution - make sur it is only for render mode and not for other mode ( Object / Edit mode ) or it’s going to slow down the response of your computer
