Surfaces disappearing when rotating view to rear

sketchup
advice

#1

Hello All,
I’m more of a beginner in SU. I’m designing and will build a bathroom vanity for my wife.
I’ve been working on this file for several weeks. It’s developed a weird property - whenever i orbit the backside of the model, surfaces disappear when i gradually zoom into the component.
If i could figure out how to attach the skp file, i would.
Thanks,
Ryan

Seeing the model would be a big help. You can attach it by clicking on the Upload button, 7th from the left in the row of buttons above the forum message window. Likely you’re running into clipping. Are you working with the camera set to Parallel Projection?

Hi DaveR, thanks for responding.
The camera is set to perspective mode; I didn’t change it (that I know of).
Thanks,
Ryan

Well, seeing the file would help to diagnose it.

I didn’t know there was a 3 MB limit for uploaded files.Bathroom_Vanity_2018019.zip (2.5 MB)

It is indeed clipping and it has to do with the very large area over which you’ve spread the various views of your model.

DaveR,
Thanks. I presume I just remove stuff from the model and it will more or less self correct.

Yes. There are other issues with the way you’ve constructed some of your components that ought to be fixed. I’m still picking through your file to see what needs fixing.

Instead of spreading out the various stages of construction as you have, you could do this with a single copy of the cabinet and correct use of layers adjusting their visibility as needed for each scene.

I think it’s time for me to sit down and RTFM.

More stuff:

You’ll want to make sure you are correcting face orientation. Set the Face Style to Monochrome and you’ll see the bottom cross bars are inside out with their back faces exposed.

It looks like some of your parts aren’t fitted correctly which could lead to erroneous dimensions.

Thanks for your help. Yes, some of the parts don’t fit together very well in some of the scenes. I got a bit lazy there. Crossbars are inside out! I wonder how i managed to do that.
Thanks again,
Ryan

I bet you don’t need to be told that getting lazy creates more work later one. :wink:

I wondered that, too.
