Hello all.
For some reason, in one of my files all surfaces appear ragged:
Thanks!
i have seen the same kind of flickering in some models. Its probably caused by having the geometry
placed really far away from the model axises.
If you move it closer to 0,0,0 it will probably get fixed. If not maybe you need to go into the components and groups and check the axis location for those components. They should not be miles away from the actual geometry.
I think there’s a plugin for resetting all the axises for all components. can’t remember what its called..
Hello, thanks for your reply and idea. In this case, the model seems to sit right on the crossing of the three axis—unless I haven’t really understood the concept of axises and the visible crossing of blue, red, and green line isn’t really the 0,0,0 point? Forgive my ignorance please.
Without access to the model the actual culprit is impossible to trace, but definitely the reason for these display artifacts is that, for instance, either
the model is very far from the origin point
it has parts very far from the origin, a tiny line is enough
it has parts, groups or components, that have their origin far from the actual geometry
My suspicion goes to the digital map that you seem to have imported. Those often have their origin point at the 0,0,0 point of the map coordinate system that is usually thousands of kilometers away, unless you are building in the middle of the bay of Guinea. Another thing, have you moved the axis to be near your model - moving the axis doesn’t move the origin.
Upload your model or a link to download your model so we can see what happening. If you can’t do that you can try few checks yourself:
Make sure everything is visible, all tags turned “on” and press zoom extents, does your core geometry disappear indicating that the camera has zoomed very far out to encompass everything in your model?
Right click on any of the axis and see if “reset” is available or greyed out, indicating that the home axis has been moved from the drawing origin (not the same).
What was the last thing you imported before it behaved like this, delete it.
Select individual elements of your drawing and copy them, paste in place into a fresh model one by one and see which thing brakes the new model.
It’s possible this is a graphics card issue, but on Mac it’s extremely unlikely, and although they can look similar this really look like “far from origin” distortion.
Hello all,
thanks so much for all your replies (and forgive the delay please, I was drowned in work) —
I followed your advice and deleted everything but one of the object groups, no change. Copying the group into a blank new file works, group appears flawless. It therefore looks like a simple file corruption, not like a problem in the elements’ setup. I’ll still send this file, since you all know more and see more than I.
Thanks again!

The artifacts in your file are caused by the camera having shifted to a location very far from the model. You don’t see it because you are using Parallel Projection. Shifting to Perspective fixes it.
Parallel projection is best used for creating traditional views but modelling in SketchUp works best in Perspective. Start practicing modelling in perspective, and you will quite fast get used to it, and parallel projection will begin to look unnatural, as it is.
Incredible. I would never have thought of that. Thanks so much!
and why do civil engineers love putting drawing origins in the middle of the pacific anyway?
Not the Pacific. Atlantic. The British imperialists made the 0° meridian go through Greenwich and no one has dared to efficiently contradict them. The French tried to make it go through Paris but failed.
that would actually make sense….but I’ve opened dwg files from civil engineers that have the origin somewhere near Easter Island
