Problem with viewport scale

JEFFJW9BB — Wed, 05 Mar 2025 22:17:22 GMT

I imported a pdf of a site plan and scaled it for my use. I then outline x-ref'd it into my standard template where I drew over it (Site Plan.pdf). I created an annotation sheet (Site Plan Anno.pdf) then finally created a sheet for printing (A101s.dwg). They are all set at architectural scale units in inches at 1/32" scale. My problem is with the viewport in paper space: See A101s.dwg.

The paper size is set at 24 x 36 but the drawing in a 1/32" scale viewport is way too big for the sheet...it should fit easily onto it.

What is going wrong?

I really appreciate your help.

Hi @JEFFJW9BB ,

The objects in the Site Plan Anno.dwg are scaled up 12 times relative to the objects in the Site Plan.dwg.

Why?

This is why you cannot use 1/32 scale in the viewport in A101s.dwg

As @maxim_k pointed out there's a scaling problem.

You can easily check by running the MEASUREGEOM command

In Site Plan.dwg the footprint measurements of the building are under 60 Feet:

But when this is xref'd into Site Plan Anno.dwg the footprint measurements of the building is no longer the same but has increased dramatically:

Maxim: You may recall from a previous post that I had a problem scaling the plan (site plan.dwg). I created the subsequent files (site plan anno.dwg and A101s.dwg) before I went back fixed the scale in site plan.dwg. I thought that if I was x-refing from a revised file (site plan.dwg) the corrected version will "flow" down. But suspecting now that it did not I detached the x-refed files and re-referenced them and they work correctly! I don't know why they did not use the correctly rescaled file but insisted on using the incorrect one - even thought I saved everything correctly.

Any way, Thank you so very much!!

Paul:

Thanks for the tip. A great tool!

See my response to Maxim's suggestion above.

You are welcome and with xrefs typically only changes made to the drawing itself would be reflected. Since that drawing was already scaled up when xrefed into the drawing initially that scale factor remains until you manually change it which in this case would be as easy as changing it from 12 to 1….cheers!!!
