Guideline Visibility Issue

Mistro11 · 1 Feb 2015, 18:26

I'm noticing some guidelines made with the measuring tape disappear when rotating the view almost as if the guides are being absorbed by the face. It gets annoying when making guides while positioning the view and then I have to settle for an angle where I can actually see the guide. Does anyone know what would cause this visibility issue?

Im using SU2015 pro BTW.

Do you think you are having visibility problems in general? I've had this before and changing the "use hardware acceleration" setting helped at that time. I'd have even regular edges looking "weak" or disappearing on surfaces, making working tedious.

No, only with the guidelines. I have hardware acceleration on. I'm trying to think what I did different lately as I never noticed this problem before. Or maybe because I'm working on a bigger model than usual? I'm gonna do some more observing while I work.

Do they become more visible as you zoom out and disappear when you zoom in?

this is an old problem (or, sounds very similar) from su7 or so..
i thought it was fixed though.. haven't seen it happen in quite a while.

does this happen to you a lot or is it only happening in a certain file?

BOX- It happens when rotating the view. Zooming in and out have no effect.

jeff- Seems to be only in my current project.
I loaded a couple of older projects and do not find this issue happening. Then back to my current project and there it is. I'm 75% finished with a 4 story museum with around 290,702 edges and 126,934 faces, 1935 component instances, 258 component definitions and 92 materials.(can't show it due to NDA) Is this considered to be a heavy model? Though some of my older buildings were smaller in size, those projects have more density content wise and never saw this guideline issue. The only thing I did differently from other projects was pull out the levels of the building for easier interior designing since each floor is unique. So the model is spread out over a 800x100ft area. Not sure if that can have anything to do with it but I don't see why it would.

Does it look something like this.
This is guide clipping, I have exaggerated this by moving a long way from the origin.

then this is something different than the thing i was talking about.. they would stay disappeared when not even touching the mouse.

to me, yeah, that's a heavy model.. it feels too much like fighting the program with models like that.
maybe something to do with it though.

do you use layers? or, does all the geometry need to be visible at once while working on it?

Mistro11 · 2 Feb 2015, 08:19

BOX- Yes that's it!

jeff- I really have to step my layer game up. But yeah, I go back and forth between floors a lot so hiding and unhiding layers every minute would drive me crazy. Under each level is the lighting for the lower floor and the first 2 have a mezzanine. If the levels were all the same layout, this would be much easier.

If it's looking like that it suggests that you have moved your guides a reasonable distance from the origin. You are sort of flirting with the clipping issue.
When you create a guide from an edge it sort of becomes related to that edge, so if you move it 800feet from it's edge it can get a bit jumpy.
Try creating a new guide from the local geometry, I'm pretty sure it will behave well.

Box- I am creating them from local geometry not from the origin. Even near the origin I get the same thing in this model. Example: I have a square column with a 3ft wide face. Making a guide on it shows that issue. Not a far distance at all.

I know this issue happens (can happen) when the insertion point of the guide happens to be "way off screen" when zoomed in

See if this helps with a guide that disappears:

select guide
(in menu Edit) Make Group
move the guide (with its local origin visible! ((show component's axes)), which was the inserrtion point upon creating it) to the location where it was giving display issues.
now that the insertion point is in or nearby the viewport the issue should be gone. With or without exploding the guide group.

Thanks for the tip Wo3Dan. I think this issue is somewhat related to why we would get clipping issues in general. After completing the floor levels I packed them back in the building which is at the origin. Since doing that, I can confirm this issue is gone.

But I would not think 800 feet would be so far to cause any issues. I see people making landscapes all the time. Unless they are miniature or set at unrealistic scales. Does Sketchup have a distance limit when it comes to modeling or is there a setting where we can control distance clipping?

use scenes. i use them a lot for this sort of stuff..
