External Reference - pdf really slow

[Anonymous]

Hello All

I am using a pdf file as an xref however while panning/zooming and some other basic commands, the response is really slow.

I have already tried using a jpg file but I loose the ability to grab the end point of a line. I am able to grab the end point of a line while using the pdf.

Is there a way I can speed this up.

I have 4 GB of ram and nothing else open, so I cannot see this being the problem

Any help would be appreciated.

Thanks in advance

Kevin

The best way to make the pdf more manageable is to put in on a locked layer.  This will dramatically improve the performance.

My comments on your brilliant solution. This old link just worked for me in 2020 using AutoCAD 2015. My cover sheets in particular with building renderings and Google map PDFs Has been a major issue for years with opening drawings both in AutoCAD and in Acrobat and loading extremely slow or even trying to move across a sheet.

I just converted both my rendering and Google maps into JPG In Photoshop and re-saved with '0' Quality option. Then I replaced all 3 In my AutoCAD drawing with PDF images and there is absolutely no loss in quality. Speed in opening and moving across my drawing in  both AutoCAD And Acrobat is instantaneous. My blessings to you for all the time. This will save both myself and my clients. Harry
