I've encountered a huge problem with trying to import PDF files into photoshop.

What I have done is to export PDF files from either AUTOCAD or illustrator. When i exported the files the lines are all very crisp and clear (example below)

when i place the file into photoshop, it instantly turns grainy... it is very obvious when i print it out on paper(example below)

i have already tried so many methods

such as making sure its 300 ppi, changing pixel sizes, checking anti aliases.
Have even tried with the CS 5 version, 2017 and 2019 versions

Please do help:(((((((

Maybe your canvas size is too small.
Check the units of the canvas when youre creating a new one.

I have the same problem with you, I tried to open the pdf file in Illustrator and it works fine but when it comes to Photoshop it gets blurry. I don't know what happens with my Photoshop

Do not zoom over 100% in Photoshop. Does the blur now go away? What is your purpose, specifically, in using Photoshop? For example, it’s ideal for turning PDF to JPEG, but useless as a PDF editor.

I don't have Autocad installed here, but you can import .DWG files into SketchUp. Is your drawing 3D?

The colouring is fairly basic, but you can use textures, and make images into textures. It also has a nice feature that there is a huge database of free 3D objects like the cars in the drawing below. It constantly astonishes me what I find in the 3D library.

SketchUp does not do 3D rendering natively, but there are some excellent addons for it. Most of the best ones are not free though.

I am not entirely sure if SketchUp is free now. It was when I started using it, but the Pro version costs now

Good gracious no. I mostly use it for engineering drawings to design things I am going to make, but I did use it to help us decide the layout for the recent refurb. (We are pretty much finished now, so I'll send you some pictures.) I used Autocad from version 10 when it was all done from a command line. The mean buggers eventually gave me a tablet, which was the size of a butchers block, and made the desk sag on that side from the weight of it.

When I got access to a workshop again, and looked at getting Autocad for my home system, I nearly fell over when I saw what it costs nowadays! At that time SketchUp was free thanks to Google, and it is a very cool piece of software. There are a ton of tutorials, but it is easy to use. Especially if you have a Space Mouse

AutoCAD & Illustrator are Vector based softwares. When you Import it in Photoshop it converts to Pixels or Vector but based on the document resolution.

So you can just increase the document resolution but also you will see these pixels when you make over 100% zoom in.

option 1

from acrobat DC open file

export it any format you want and any resolution

if you don't have DC

option 2

1. if you have illustrator open it there

2. razstersize it the highest resolution

3. auto trace it full color - regardless that its low color

4. if looks decent - rasterize again at 300 dpi this time and export it as a .png and choose large dimensions

5. now open that in photoshop

option 3

open in photoshop

change it to bw , then change to bit map - set a large resolution

2. save .bmp

3. open .bmp in IL

3. rasterize image 1200 DPI

4. Autotrace

5. expand

6. save as .pdf or any format you like

you are overzooming - export it as a .svg and open it in your browser and you will see it will be 100% no loss

and WHY should someone place a rasterized PDF inside Photoshop in good times of Smart-Objects?

give it a try.

Yes. This is because Photoshop is the wrong tool. What you need is a colour mapping/CAD tool. No Adobe tool can be used to do this well.

as a sample, this is an example of what i did in the past which was simply adding colors from the paint bucket tool

If you create a Smart Object like I said previously, you can paint bucket a layer underneath the Smart Object (if that makes sense)

I have tried doing so but it is equally as grainy which would make the colors grainy as well unless I increase the dpi

It may be faster in Photoshop, but it isn't the right tool. Find a way to do it in Illustrator. (Which is NOT however, a general PDF editor!! Use it only for Illustrator PDFs. We cannot offer you a solution for editing AutoCAD documents nicely in any app except AutoCAD.)
