Clipping plane needs a fix!
-
your written example appears to be such an uncommon prerequisite, can you post an 'real' example skp with the issue, there may be a simple solution to your particular issues...
SU already has full clipping plane control when you use 'Section Planes', it's feasible that this feature could be hindered by allowing user adjustment of the base settings...

I'm working on a 3 mile section (5.23 km) of roadway with trees, buildings, cars, road striping, etc.
Sketchup is handling the model itself beautifully. The one and only problem is the clipping plane. I need to do a flythrough at the eye level of a vehicle that follows the roadway. However, only the top 1/3rd of the screen shows the model as the rest is clipped off. If I could lock my clipping planes to a few thousand feet view distance then I'd be set since that would probably fix it.
EDIT: Your comment about section planes made me try an experiment and clip a segment that's only 500 feet in length. Nothing else is visible. It still has massive viewport clipping problems.
Even with geometry being clipped out with section planes, it doesn't have any effect whatsoever.

have you tried using an 'Advanced Camera' with a fixed aspect ratio, fov and focal length and 'View thru camera'?
just a thought...
john -
Yeah, I messed around with a bunch of advanced camera settings, but if anything, it just makes it worse. Real bummer.
Something else that's very interesting is that adjusting shadows will tweak the clipping plane on the fly. If I adjust the time of day, you can see the clipping plane move in and out from the objects in view.
Weird.

from my understanding, 60 degrees fov requires an extreme aspect ratio to avoid OpenGL clipping...
http://ogldev.atspace.co.uk/www/tutorial12/tutorial12.htmlif you shorten you SU window, does the clipping improve?
i.e. try 3:1 aspect ratio of the actual window...
if your on a mac I have a plugin that makes that easier to do...
john -
Yep, I've tried messing with aspect ratio, screen size, shadows, resolution, advanced graphics card overrides, etc. without any luck whatsoever.

Hello,
I've been using Sketchup from the beginning, have never really had clipping plane issues in the past that were much of a bother until recently. Working on a model that is relatively small compared to some I've constructed and I can't get close enough to objects while editing...for example a 1/2" dia. bolt. This is driving me insane to be honest and I have exhausted my options. I've opened a fresh new drawing, no issues editing something small. I've tried turning off layers, deleting everything around what I'm trying to edit...no luck. I can zoom in fairly close to an object (not great, but close enough to edit) as soon as I right click on edit group or component it disappears from view....I saved it as a sketchup 8 file and tried it there...same results. I'm sure it's something simple that I have overlooked.....Help would be greatly appreciated.
Thanks -
The only way to fix the clipping issue is to zoom way out and then switch to parallel projection for your camera. Now you'll be able to zoom back in without clipping. Turning off layers/hiding objects has zero effect on the clipping plane issue. The only way to fix it is to completely remove all objects on those layers.
I set my F12 key to be my switch between parallel and perspective camera views and it's helpful.

Very good advise...at least there is a work around, Thank you.. I do absolutely hate working in parallel projection but beggars can't be choosers... Appreciate the help!
-
It really is a bummer. I hate showing my boss a model I've obviously put a lot of time into, which works great in every way... until I need to get a ground floor view (through a window, for example).
Fixing the clipping plane is obviously a hard coded fact-of-life. But I wish I could temporarily disable it when standing still...

I'm certainly no expert on computer graphics but It seems to me that computing has reached a level of sophistication in both hardware and software to where these issues should not exist.

I was just having the same problem and the above fixed my issue, thank you
