Affinity Designer - Copy Paste between PDF to new document?

[TurboCooler]

I opened a PDF document that is basically boxes and lines.

 

Affinity Designer converted them to curves

 

I copy the items from the PDF to a new document and AF shrinks the object to less than 1/4 of the original size.  This happens no matter if I use Paste or any of the Paste Special options or no formatting.  I get a very tiny representation

 

Both documents are 8.5" x 11in documents

 

What am I missing?  What do I need to adjust?

 

There is nothing special with the PDF and it is open source.  I have attached it.

If you are copying items in a PDF imported into Designer to a new Designer document, make sure the DPI setting in the new one matches whatever it is shown for the PDF.

 

My guess is the PDF was imported at an estimated 72 DPI, & the new AD document was created using the "Letter (ASNI A)" print page preset, which defaults to 300 DPI. Thus, the pasted items are reduced by a factor of 72/300, or about to 1/4 of the original size.

 

Change the DPI setting of the new document to 72 or of the original in Designer to 300 DPI & the size should be the same.
