scale pdf

[gffarchitecture]

I would like to scale a pdf.

Its easy to scale a picture for example to 50% of the original size and back. I have to scale different architecture plans (always .pdf) where its important, that the scale is right. I haven't found the options to scale a PDF yet. It should work without doing a picture-format like jpeg instead of pdf, because the output of the CAD programm is pdf.

How can I scale a PDF to 50% of the original format?

Hope my English is enough understandable to what I mean. Many thanks for answers.

Welcome to the Serif Affinity forums, @gffarchitecture.

As with any layer, the Transform studio panel should be able to handle it. Select the layer with the Move Tool, and in the Transform panel you can choose the origin point (perhaps select the center), and then specify the width and height you want. If you lock the aspect ratio, you could just put *=50% into either the W or the H box.

Thank you for answering.

Yes, I know this way to reduce the pdf. Another person who works with the file doesn't know the original size. Or I have a magazine with 42 scale architecture plans. In the end I don't know what I have scaled and not.

Id would be nice, when there is a option like a jpeg:

Original: Plan 1:100 - size 100%

Layout: Plan 1:200 - size 50%

To check, I have to know that the plan is 50% of the original.

How can I handle it?

It is not a comfortable way, but you can look up the scaling within the Resource Manager. Click a PDF and have a look at Placed DPI, then have look at the right side at Original DPI. So you can calculate the zoom factor. As said, not comfortable, but better than nothing.
