Is it possible to retrieve a former version of a file?

Hello

I would like to know if it is possible to come back to a former version of a file ?

I have a big bug and can’t work on the file anymore. The display is all blurry. (see image attached)

This is quite a big project and if all is lost, well, I guess I’m fucked

Thanks for your help

How far from the model origin is the part you are working on?

Do you have items far away from the origin?

Can you try the SKB file?

Do you use TimeMachine or similar incremental backup software?

Can you share the model?! If it is too large for a reply - use a file sharing service and post a public link.

Hello,

Thks for your reply ! Apparently, no, can’t use the skb file.

I don’t have a backup software, I did not know those existed…

Here is a link of the file : Plan cegelec RDC - vf.skp is available for download

Thks !

That looks like your model is really far away from the world origin (the starting axis) / is inside a big group.

If you click zoom to extents does it zoom out really far?

yes. I think the problem is that I imported a component on another scale and I can’t find it to erase it. I think it is really far from the origin. I just don’t know how to correct it

You also have an incredible amount of geometry:

I normally work with files this size, but the slow down / lag on this one is something else. Trying to isolate the issue. But whatever is causing the issue is so far away that I can’t see it.

This is the length of the line I drew to give a sense of how far away whatever you did is messing up your model:

As you’ve not got any scenes, copy the main building model and paste it into a fresh file - that will correct it.

That solved it for me on this file, but I cant work out what has caused it in your original mode. Very odd

yes, that’s what I am trying to do.

I know the file has a lot of geometry. The base of the file was given to me and I had to make do with it. Bu maybe I should have started from scratch !

Thanks for your help

I feel like I’ve missed something obvious

What’s in this file causing the issue?

broken.skp (157.0 KB)

ignore.

OMG. that’s so weird. It was all buggy and glitchy, reloaded it and it was ok.

Normally solving something precision based happens straight away, but strangely in this file I have to open and close sketchup for it to kick in. I’ve never seen that before.

Almost always better to start from scratch. Or import and redraw things to be sure that lines that should connect or be parallel are actually connected and parallel. I often redraw/trace over imported CAD linework since I don’t trust CAD exports unless I’m the one who’s made them.

The component named étage cegelecx is located an absurd distance from the rest of the model. It contains 4703988 edges, almost a third of the model total. It looks like this:


If you don’t need that component, select it in the outliner and delete it. Then purge the model. Otherwise, select it in the outliner, copy it, and paste into a new, clean model to reset its transformation. Then you can copy it back into your original model at some sensible location. It will probably create a new component definition, so once again you should purge the model.
