drawing view scale

DaveClark · ‎Sep 05, 2012

Hello Everyone,

I've got a user with a multi-sheet drawing of an assembly (around 50 sheets). Most of the sheets detail individual parts of the assembly. On four of them, the piece part display is blown up so large that it's way larger than the drawing format. Each of the four sheets has a different part. However, the view scale and any measurement shows up correctly, and it prints correctly. If a new view is created, it shows up at the proper scale. Has anyone seen this, and how did you fix it without deleting all of the views on the sheet and starting over? Exiting and restarting Creo did not fix the issue. We are using Creo 2.0, M010.

Thanks,

I should also note, this drawing package was working fine for a number of days. All of the sheets and views were displaying properly. We can't seem to determine what action may have caused the display to get out of scale on these four sheets, but at one time they were fine.

Thanks,

I have recently run into something seeming to be a bug so see if this might be the problem...

When placing a view, I use combined states for two different views of a part, one flat pattern and one bent. For some reason, only one of the two views would follow the default scale. The other view had to be set using the properties/scale option.

I will also add that having 50 sheets to a drawing is very bold. If that file ever got corrupted, you would be in a world of hurt. I've already had drawing corruption using datum tag annotations. Be careful!

I've attached some images that hopefully clarify what we're looking at. In the 01 image, this is the display when the sheet is viewed. In the 02 images, you can see a new view added and it's the correct scale (as was the other views when the sheet was created). In the 03 image, it's zoomed out so you can get the full effect.

I hope the image file sizes aren't too large.

Thanks,

I wonder if that scale factor is exactly 25.4...

or 2(scale) x 25.4. Could it be that there is a SAE to SI issue somewhere in the model?

What date code and version are you using?

Can you submit this to PTC support for evaluation?

This is the kind of corruption I was refering to. If you redefine these views, will they remain stable of willthey again corrupt themselves?

I'll have the user check out the file and see if there are unit conversion issues. The user is on Creo 2.0 M010, and I've opened the file using M020 to no avail.

Thanks,

It is very important that these files find their way back to PTC for resolution. They can't fix something they don't know about.

You can go to the PTC update advisor to see if there is any bug like this reported before.

You need an account to access this but the information can be helpful:

https://www.ptc.com/appserver/cs/update_advisor/update_advisor.jsp

Just plug in the comparison and it will spit out a lot of data. There is a second tab to show what issues have been reported in the current release.

Thanks to all who replied. I know it sounds excessive to some having 50 sheets to a drawing, but it's been working here for 13+ years so changing the drawing package philosophy isn't something that would happen overnight.

Regenerating the model just would not do the trick either. It also was not related to units.

What solved it was right clicking the drawing tab and going to "update". It fixed the graphics and everything is back to normal. My only question is, why is update buried on the tab and not in the ribbon, or what separates update from regenerate? (as you may notice, I'm not a drawing/drafting expert by any stretch of the imagination, surface modeling is my specialty).

Thanks,

Glad you found a simple solution.

If you click on the Review tab in the ribbon when a drawing is open, you will see Update right below regenrate along with another view update options. I think the right click might be better as it only updates the sheet you are currently on.

I remember in 2000i, there use to be a "Regenerate: Draft". These update options must have replaced this. I never really noticed they did anything, but now we know 🙂
