My files seem be getting corrupted after a few hours of working on them. The files open, but the lines are all in the wrong place and “distorted”. Below is an example of a file when it was good, and then an hour later after it had become corrupted.
As I’m a new user I’m not allowed to embed more than a single image, so I’m only including a screenshot of the model after it got corrupted. Many lines missing, lines that are no longer straight etc.
The same file saved an hour later, when I opened it the next day:
Share the actual .skp file so we can see what you’ve got and try your file on a different machine. It looks like you have at least part of the model situated at a huge distance from the origin.
It’s as I guessed. You have stuff placed at a long distance from the rest of the model. This is what I see when I hit Zoom Extents. This will cause graphical issue.
I’ve moved the model closer to the origin and fixed incorrect tag usage. See if this looks better for you. You’ll need to redo the camera placement for your scenes.
By way of some explanation of whats going on here you have a label in your model that is 5,229.9 Km away, larger than the distance across North America. The graphics engine tries to show the location and relation of the objects in your model but it is having to “think” about too large and area and so the performance begins to degrade and the image you see begins to become distorted. This can happen in degrees, in your case the size is enormous and the distortion is bad. There is no exact “maximum” for sizes but in general try to keep the total model space within 1 km of the origin, then distortion rarely happens. I’ve used up to a mile without effect and others have gone larger, but usually this is not an issue as most thing modeled are smaller than a large building and fit near the origin. In your case this was likely an anomaly caused by labeling something then deleting the thing the label was attached to which can sometimes cause the label to shoot off into the stratosphere. Zoom Extents is a great way to tell if you have elements far from the origin.
Thank you so much DaveR! You can’t imagine how many hours of re-work you have saved me
I had no idea about this issue, and I’m also not sure how those labels got so far away from the rest of the model, but I’ll be using Zoom Extents a lot more now to check things.
There are a couple of vase components many miles from the rest of the model. When I shift to Plan view and hit Zoom Extents it looks like a blank model space with the origin way up at the top.
I’ll upload the file and give you the link as soon as it’s available.
BTW, do you really have to keep all that stuff surrounding the main space in your model? Seems to me that just creates clutter and causes the file to be larger than it needs to be.
It’s not a stupid question, but a problem that many novices encounter. Tags should only be applied to groups and components. Otherwise very confusing issues with visibility are likely to occur. @DaveR used an extension to find and correct the bad usages automatically.
In SketchUp ALL edges and faces should be created and remain untagged. Tags should only be given to groups and components.
Steve got his reply in first and yes, I used an extension called Default Tag Geometry from Sketchucation to quickly fix your model.
Leave Untagged active at all times. Leave all edges and faces untagged. Give tags to groups and components. Simple workflow which if followed makes the modeling process easier. In programs that use layers, you have to constantly be chasing the active layer while editing or working on the file. There’s none of that in SketchUp if you follow the “rule”.
This wound up reducing the file only by about 12% but one thing to look at especially is the fact that there were 58 materials that could be merged. That means there were identical copies of materials. That adds unneeded bloat to your file and if you’re going to do anything with those materials in a rendering application, it means you more textures to manage.
