I found a copy of version 7 on my computer, installed it but had major problems with being able to load a version 8 model in version 7. Would always load it in version 8, even if I specified version 7 as the program I wanted to open it with. Noticed your comment about putting it in a separate folder so just uninstalled version 7 and will give that a try. Boy this program is fun

Actually I thought that might happen, thought maybe it would be different if they were by themselves instead of part of the entire model. Oh well, I know now to watch out for it, and hopefully deselecting the objects before I paste them will continue to work around the glitch. Thanks for your help.

Sure. They're not very good, I'm just learning. Hope I attached it ok.

67 GTO Seats MASTER pasted in place.skp

Just tried something - it seems if I deselect the objects after I copy them, before I paste them, it doesn't happen. Man this is one quirky program. Guess that just adds to it's appeal. Maybe, sorta. Kinda.

Seems like if it was going to screw up something it would be the copy, not the original.

Yes, it also shows up in monochrome. Nothing I do gets rid of it, and it's really worrying me.

So if I downloaded an earlier version of SU it might work better? What version should I try, and can I have two different versions running on the same computer, and if so where would I find an earlier version? How's that for a bunch of questions? Jeez, that's another question

Sometimes when I copy an object and paste it to second SU program, the pasted object looks fine, but the original that I copied it from takes on a strange diamond pattern as shown. Am I doing something wrong, any way to avoid this? It's kinda hard to see so I've attached before and after photos (the seats are what I copied)

Has anyone come up with a solution to Zorro causing SU to crash? It's such a handy tool when it works, absolutely fantastic, but it constantly crashes the program, it's driving me nuts. I've read everything I can find here in the forums and people have talked about it crashing a lot but I couldn't find any mention of a solution to the problem. I've also tried the equivalent tool in Subdivide and Smooth, same results. Any help or suggestions to at least minimize the problem would be greatly appreciated.

Allow me to demonstrate my ignorance - when "purging" was mentioned earlier, I assumed it just meant to go thru your model and physically delete all the stuff you no longer need. I did not know that it was also a menu item under Windows Also, I do not know what you mean by applying a material to an edge, or why that would make a difference. I've only been using SU for about three weeks, and the amount of stuff I don't know seems to be increasing instead of decreasing. Another Michigan winter is settling in and I am determined to use the coming miserable months and the books I recently bought to learn the things I need to in order to eventually create the type and quality of models that I have in mind. It certainly won't interfere with my life, I don't have one .

OK, did as you suggested, and lo and behold, a couple of wood textures I had added to the dash were PNG instead of JPG. I generally like to work with the PNG format because it's not lossy like JPG. Anyhow, of course they were much larger than they would have been had they been converted to JPG first. Even tho I had deleted them from my model, they were still in the "in model" materials folder. Lesson learned, and I really appreciate all your help. Crisis averted, and I can now sleep at night

Well the files are too big to attach here. I had saved probably 7 different versions after the "big jump", didn't notice the increase in file size, and no reason to suspect such a thing might happen. Anyhow, I have spent the past several hours copying and pasting all the changes I had made since it jumped in size onto the last version that was "normal",and now have a complete up-to-date version. And when I saved it, the file size was back to normal, so it doesn't seem like any changes I had made were responsible, since all those changes are incorporated into the new model. My obsession with saving, saving, saving paid off big time, and now I know to keep a close eye on the file size each time I do save a new version. Still, it would be so nice to know just what the heck did happen, it's gonna bug me forever.

There was no need to purge - the only difference between the two was a couple of minor changes to the dash. How can that cause a jump of almost 500 percent in file size?

Thanks Jeff . Wish I had asked this question a long time ago, would have saved me a bunch of work.

Just had a bit of a shocker. My model was running at right about 11mb. Been saving versions frequently, just in case, and just noticed that it suddenly shot up to almost 50mb!!!! Very minor differences between the two, no hidden stuff. Please tell me that this is something that sometimes happens and it's very easily fixed. Don't make me shoot my computer.

Let's say I have several saved versions of a model, and I find something in an earlier version that I want to copy to a newer version. Is there any way to copy and paste it so that it appears in exactly the same place in the newer version?

Wow, this is a lot of great information that I'm sure will come in very handy when creating my models. Things you don't find in a book, which is why I come here for the good "inside" stuff. It's a lot to think about, unfortunately I only have two active brain cells left (and one of them is on life support) so it's gonna take a lot of experimenting and trial and error on my part to see how to best use all this. Once again, thanks for taking the time to help a SU novice. Maybe twenty years down the road when I become an expert I can do the same for other newcomers. I love this program, I've had it on my puter for several years but didn't pay much attention to it, thought it was just something amusing to play with, had no idea of it's capabilities. Now I'm realizing the limitations on my capabilities. I think I may have to build a more powerful computer just for this, finally have to graduate from the old Pentium 4. I've been fighting that for a long time, but I guess it's time. Hey, it's only money

But can you please explain to me what is doing this? I'd really like to understand, what did he do when he made this model that is doing this?

It's not my model, I downloaded it from the warehouse.

When I do that the tread goes away before I explode it.
