Hi all,
Summarizing my findings explained in the post below here is what you can try:
- You may want to check for lost objects distant from the scene (or from the origin)
- You may want to check for distant entities in imported or linked files or blocks.
- You may want to move your scene closer to the origin
- You may want to turn off the ground plane (apparently now through the
Options>>View)
- You may want to hide your camera.
I have revisited the situation on my end now with Rhino7. And trying to bring McNeel back on this issue (@pascal @wim).
I wanted to do a quick summary but it turned a bit longer. I tested the files that I created in Rhino5 at the beginning of this thread. I may find some time to test new ones but not now.
I am not sure when it occurs since does not always affect similar files.
Often it seems related to distance from the Word origin. Either the scene is set very far from the origin, or there are lost entities far from the origin. These lost entities can also be in imported or linked files or block. This may be aggravated if the file is in millimeters and the distances are of several kilometers.
One solution may be to move your scene closer to the origin, but this may be inconvenient especially in topographical survey or other files that need to be georeferenced.
I was able to replicate this in a file done from scratch with no units. I modelled a cylinder with radius 60 units at the origin, and a small cube about 2000 units away. When I delete the cube, the problem disappears. These are very minor distances in the files I normally model. Again, this a file done in Rhino 5 at the beginning of this thread 3 years ago.
It was referred that it may have to do with hardware limitations. I am less inclined to believe this because similar models do not have the same issue.
The other reason that I do not think it is a hardware limitation is that once it starts occurring, it seems to persist even after deleting and purging all geometry, keeping extremely basic geometry placeholders (as in the images at the beginning of this thread).
Another issue that affects the problem, in my test files, is showing the camera. In one of the test files, the view is ok initially but once the Camera>>Show, the clipping happens even more obviously (i.e. clipping the geometry 41000 milimeters from the camera). When the camera is hidden, the clipping is about 5000 milimeters from the camera.
@pascal,
One thing that I have noticed today, is that turning the GroundPlane = Off in the Ground Plane menu (which used to improve the situation) does not work on the file I am testing. The clipping plane only disappears when you turn off through the Display Mode options (Options>>View>>Display Modes>>Ghosted>>Ground plane settings = Off). I assumed this was the same “Offing” but apparently is different.
Summarizing (I also put this list at the beginning of the post):
You may want to check for distant lost objects from the scene (or from the origin)
You may want to check for distant entities in imported or linked files or blocks.
You may want to move your scene closer to the origin
You may want to turn off the ground plane (apparently now through the Options>>View)
You may want to hide your camera.
Please solve it…
Thanks, N
