Sketchup orgin?

Paul,

What happens if you hide the plan drawing and the elevation images? Can you then zoom in on details on the house without clipping?

Dave, I work with the images turned off and use them mostly for reference and it matters not if they are turned on or off as for clipping.
(By the way, I have been trying to make it to a Minnesota users group meeting since it began and I am still planning on doing so. Hope to shake your hand & say hi in the not too distant future.)

Krisidius,
I did try earlier isolating the building itself in a separate file and the clipping remains the same.
I do like your description of how to handle buildings separate from site though and will use that method on another project in which I have 10 buildings spread out on a very large site.

Rich, no such luck.

Really? damnit...

Ok I have one more solution...

some component in the model has an extremely small scale. like a lamp or a chair is extremely over detailed. do you have any furniture yet?

Chris Fullmer

I think (I have not completely verified this) but you might have a component whose axis is waaaay off the origin of the model, and that could also make the model act poorly. Maybe someone already suggested that, but I didn't see it as I skimmed through this thread.

Krisidious

Yes... I like what Chris has there. make sure to turn on component axises...

I just got done typing a very long winded, highly detailed and stunningly interesting response to your further input with results of testing each of your suggestions complete with photos...I took a quick preview..and crash! I lost the site and my post.

So shorter version.
I did find a distant axis related to three reference planes I had in the model (see image below)
thar she blows.PNG

Clipping improved maybe just a bit when I removed those planes. Not night & day though.

Component testing:
I do not have any furniture or other highly detailed components in the model, but decided to start testing by removing groups and components that I know I have not used before and that had been scaled.

Test area image:

Clipping with site image in:

close up.PNG

Clipping with site image removed:

yes!.PNG

That site image seems to be the culprit. It was originally an image when I first imported it and I exploded it, grouped it, and scaled it way down to match the model size.

Site image:
with site.PNG

I will now get my site work done and get this problem maker out of my model. I don't know if it is just the size of the site image or the fact that I scaled it way down or...

You guys have been great to keep digging at this thing.

Thank you!

Paul, we seem to be getting closer to solving this. I'd have loved to have read your "highly detailed and stunningly interesting response."

I would suggest that when you import your site image you either leave it as an image or, if there's a compelling reason to have it as a component/group in your model, that you correct its size prior to componentizing/grouping. This will help you avoid potential size issues. If you do group first, open the group and scale the geometry and the texture.

Out of curiosity, is there a reason for converting the image to a texture in a group?

Now, on to your trim example. Suppose you either turn off layers for or otherwise hide stuff that you don't need to see while you work on that detail? Can you then zoom in close to the detail and avoid the clipping?

I'd love to get to the meeting again and shake your hand, too, Paul. It would be nice to meet considering we aren't really that far apart.

pmolson

Dave, The reason I explode images and regroup them is that I have found in the past that images of the size of a 1:1 site plan seem to cause sluggishness in models...at least I think that's why I do it. To be honest, I have been doing it that way long enough that I have forgotten exactly why I started doing it in the first place. Creature of habit I guess.

I think what I will do in the future is to import and resize the site image in a separate drawing and leave it as an image and then import it into its final resting place. That is what I do with cad files and it seems to keep things tidy.

The turning off of the site image layer and other large groups like the google terrain etc. made no difference in the clipping. Only erasing completely the site image group made a difference.

Thanks for your time, see you sometime in the not too distant future.

Paul

Dave R

Paul, I wonder if leaving the image as an image instead of making it a group with a material on it would eliminate the problem.

Maybe we'll have to hook up sometime other than the meeting. We could meet in Lake City and go for a sail or something.

Cheers,

Dave

3d apps have clipping planes to reduce the rendering load on the CPU and/or GPU. There are 6 of these( top/bottom/ left/ right and front/back). In some cases there is occlusion culling also( back of buildings etc)The following are some of the question that come to mind( In the form of statements):
The field of view is important and should be set at about 25 degs. (per Su) but changing that could help your issue;
Minimization of rendering load should help per Daves suggestion above. However, my self question is: Is the clipping plane adaptive and changes if I turn layers on/ off or does one have to restart the program?;
Who sets the clipping planes, SU or the Graphics card, and does it change if hardware acceleration is on or off?
Given parts of the model are not displayed behind the section plane can that be used to help this problem;
For large model extents the use of scenes can be used to help this problem also;
Any use of materials the have reflective like properties can also cause problems. All model work should be done in the monochrome rendering mode if you are running into this problem. Display materials only when necessary.
In face styles turn enable transparency off. This affected my frames per second significantly when I ran some speed test ,but my PC is long in the tooth;
Avoid the use of back edges style.
If I have repeated some of the posted intents above please accept my apologies!

The world axis does not effect clipping though...correct? Mine is set by template to my region, Minneapolis. When importing Google earth grab, that resets the world axis to the grab for that particular model if I am not mistaken.
Thanks

Correct. The WGS dataum does not curve fit some location good and they use a different datum. If you use their x,y data for your model in GE then location can be off meters.
For example WGS 0 meridian does not run through Greenwich.

If you want to see where the clipping planes are set, open model then consul and enter Sketchup.send_action 10624 ref http://sketchucation.com/forums/viewtopic.php?f=180&t=44076

Hi folks.

Unless my knowledge of English is not complete, after all French is my native language, there are 2 "i" in or****i****gin.

Thanks and best regards.

Just ideas.

Depends on what part of the Untied States you live in... We often like to remove letters from words. We also like to combine words. Y'all

Seems worth a try.

You mean like...a liesure time activity? non work related...just for fun? Hmmmmm, interesting concept. Have to think about that next time I am not working or thinking about work.

Mac 1, thanks for the techno info. I often get lost when I try to follow one of your posts. Your knowlage goes deeper than...well...me actualy.

Paul, there'd be room on the boat if you wanted to do some drawing work while you're sailing.
