.PDF Grips

[Kremer]

Good evening,

 

I was curious why sometimes when I drop a .pdf into a drawing I am able to select grips on the lines contained within it.

 

What I mean is that when I am using, say the line command, I am able to select the endpoint of a line in the .pdf.

 

I have had other cases where I was forced to trace the line by eye, and I was curious what determines whether or not there are grips.

 

Many thanks in advance

I'm not entirely sure so don't quote me on this, but I believe it has to do with which version of CAD created the PDF and how it was created. If you create PDFs with layers I think it recognises separate entities within the drawing, and so when it's imported back into CAD these separate entities are still recognised. This allows you to snap to particular lines. Only a guess but only thing I can think of.

I'm also guessing a bit, but I know that there are two types (at least) of PDFs.

 

One type is a Vector PDF (contains the vector information of lines etc).

The other is a Raster PDF (just a picture).

 

I would guess that the ones that you can snap to are Vector PDFs.

Mmmm, Nuke said what I was trying to say in much better terms.
