Updating Existing Dimensions After Scaling

Anonymous — Wed, 27 Mar 2019 15:41:38 GMT

I've drawn a 2' square. I've pulled dimensions showing that the height and width are 2'. I selected the part and dimensions and scaled them up 2x. My dimensions are showing the part is now 4' tall and 4' wide. I adjusted the dimlfac from 1 to 0.5. If I pull new dimensions on the part they will show it to be 2' tall and 2' wide. How do I apply the dimlfac change to existing dimensions? Is there a command that does this? I appreciate the help.

Go to dimstyle and change it, it should update all existing that use the style.

To change the DIMLFAC of existing dimensions, you need to select the dimensions and the in the properties panel, under Primary Units adjust the Dimension scale Linear

You can fix your issue if you follow the advice that's been previously posted. My question is why are you scaling and not drawing 1:1 and using annotative dims?

Why are you scaling the object, then "fudging" the dimensions to compensate?

If you have manually set DIMLFAC (at the command prompt), then
command -DIMSTYLE "Apply" and select the existing dimensions.
Please note the hyphen "-" in front.

To make the dimension style permanent with this adjusted DIMLFAC,
command "DIM" "Save" "TheCurrentDimensionStyle" "Yes" "eXit"

No dialog required.

I don't want to change all of the dimensions on the DWG. Think of this as a detailed view of a small aspect of the larger part. It's been many years since I used AutoCAD. I "learned" how to draft on AutoCAD 2010. I am now using AutoCAD 2019. I could've sworn I remembered there being a short cut command to update dimensions after changing the DIMLFAC to correspond with the scaled up view, but I could be mistaken. I do know that I did not have to change the DIMSTYLE when I did this. I appreciate the help.

Thanks for the response. I do start drawing at a 1:1, but sometimes I need to zoom in on a specific part. Scaling up a selection of the part allows me to provide better details. I'll have to look into annotative dims as I am not sure I've used them before. Thanks for the help.

A larger view will allow for more clarity when detailing/dimensioning.

I don't want to change the DIMSTYLE at all. Not every dimension will require updating as the entire part isn't being enlarged. I appreciate the help.

So we do all of that in a viewport in PAPERSPACE: that way you always draw at 1:, you never fudge a dimension, you never fudge a drawing either.

I take it you never transitioned to learn how to use Layouts and viewports? We issue sheets all day long with 3-4 different scales on one sheet in a layout without EVER having to fudge anything in modelspace.

Now would be a good time to learn if you are up to it, it will increase your productivity and lessen mistakes in modelspace.
