Detail scale is not true to scale

Hi all,

I ran into a problem today when I discovered that my 1:1 details are not 1:1. I did some investigation and saw someone posted something similar, so I wanted to recreate the problem on a different file, which I cannot. The detail scaling has given me problems before (R8 not 7) when I key in a scale factor; the detail didn’t reflect what I typed in. So I used my mouse scroll, the scale changed, but not to the desirable number that I needed. Let me describe what happened.

The detail scale shows 1:1, but it’s actually 1:1.3 or something similar. When I realized the scale was off, I went back to the model scale and re-entered the number “1,” and this time around, the detail changed to the actual scale.

This is scary because I have always trusted the scale of my details when I was in R7. Since I can’t recreate the problem I will keep an eye out and hopefully, someone else can send you guys a file to show what’s going wrong.

Thanks

Hi Hogan - thanks, a repeatable example would certainly be helpful. I’ll see if I can make this happen.

When you set the scale of the detail, LOCK the detail with the checkbox. Otherwise an accidental or reflex zoom when you are in the detail (double click) will change the detail scale. If you need to pan the detail, unlock it and pan, but do not scroll the mouse wheel while it is unlocked. Then lock it again immediately after.

Hi @Helvetosaur I understand that very well and I learned that the hard way. :slight_smile: I locked the detail and held ALT+ click and drag gumball to copy the 1:1 detail then found out that they were not 1:1. I unlocked it just to show the font clearer in the screenshot.

@pascal I gave it more tries to recreate the problem but I couldn’t, unfortunately.

Thanks!

I didn’t get that from your post above… so when you copy a detail, the copy changes scale?

@Helvetosaur That was just part of the actions I did before I found the scale changed. I don’t think that’s the reason because when I recreated a similar situation the problem didn’t repeat.
