Scale Reference PDF drawing issue-Help

[Sengna]

I tried to scale reference the PDF equipment drawing so that it will become the actual equipment size, the problem that i have is that when i selected scale command and pick a base point, and typed R (Ref)and them it asked for the reference length then i just select the conner of the equipment and drag it up for 31" for actual equipment size but nothing happen, the PDF was inserted in 8.5 x11" it was hard to snap to any end of the Equipment since it in PDF. what did i do wrong here, please any help is very much appreciate.

Thanks

When you use the [R]eference option, you have to pick a basepoint (although where doesn't really matter) then pick a 1st and 2nd point that are a known distance apart.... then type in the known distance.

Sure, what i did was i drew the vertical line to match with the equipment width since it was hard to snap to any point when work with PDF, then i pick the base point, R- for reference, then pick the first point of the reference length and then snap to the second point up for 31" but the size of the equipment remain the same but it as to " specify new length or Point.

See if you can see anything different here than what you are doing?

I got it now, i know what i did wrong, after entered R- ref, I specified the first point of the ref length and then I snapped the second point of the ref length to then end of the 31” vertical line which I should snap to the end of the equipment width. Thanks so much for your advice,

how can i clip/crop out then border of the inserted PDF and just leave it only the equipment do you know? I tried the clip image command but it didn't work. I saw you bring up the PDF underlay how can i do that? thanks

This Youtube video should help with clipping PDF's -->

 

The window that said "PDF Underlay" was just the Properties palette. That should pop up when double clicking on the PDF (CTRL+1 also opens the Properties Palette)

 

Disclaimer: I avoid PDF's in AutoCAD as much as possible due to their tendancy to drag AutoCAD down, especially zooming/panning. Use PDF's in AutoCAD sparingly.
