Hello, I am a new user to photoshop so im sure this is an easy fiaxable issue!

I do my Architectural work on AutoCAD and have been looking for new ways to format and edit my work. I bought a year subscription of the Photoshop and other softwares but have a problem.

When i set up my page and then import my CAD PDF drawings into photoshop, the finer lines on my work as an all look extremely faint and nothing like they do on the PDF document.

How do i fix this issue, is it a page set up issue or a background issue ect?

Many thanks for your help

Hi

I had the same issue when I imported pdf made by CAD into PS. All of my lines went really thin. When you import the pdf page, chose "Media box", and when PS pastes it on your page, unchek Anti-alias then click OK.

I hope it will work.

The easiest fix to this issue is creating a new fill/adjustment layer, and moving the brightness down to all the way to -150.

This issue happens because when you draft your work you often use different lineweights and the thinner the lineweight the lighter it will appear when you import it onto photoshop

Zoomed out it may look dark but once you zoom in you can actually see the different lineweights in your drawing.

Hope this helps.

If the CAD file has been saved as a PDF, I'd recommend running the PDF through Acrobat Pro's Print Production Tools: Preflight/Fixup where a minimum line weight can be set:

Hi not sure if you got your answer, but when I import a CADD PDF into photoshop my lines disappear. What has worked for me in the past - and you should know I am very inexperienced in photoshop >

FILTER

>OTHER

>>MINIMUM

>>ADJUST RADIUS BY 1

Hopefully this makes sense.

I was having the same issue. I fixed it by checking my lineweights in CAD. If you view yoru pdf as the whole sheet, it looks all like the same linetype. Zoom in a lot and you can actually see the different line weights. Double check your line weights. When you plot, make sure the "plot lineweights" is on and test out which thickness you want.

Hope this helps!

I think I have even received a pdf with a linewight of 0 sometime and that may preview very unreliably.

Hi! Another question might be is it a resolution issue? When you bring your PDF into Photoshop, in the import dialog, what resolution and page size are you using to import? When you look at the lines are you viewing the image at 100% or smaller?

There are a several ways you can darken the lines--here are a couple of easy ones:

1. Duplicate the layer and then set the Blending Mode of the duplicated layer to Multiply. You can then use the Layer Opacity to adjust the darknesss.

2. You can also use Levels or Curves to darken the image.

Let us know if that helps, or if you have any other questions!

This may be slightly off topic but I wonder why you think creating a PDF from your ACad drawings and then loading that PDF in Photoshop is a good way to Work on (I take that as Edit) your drawings?

Back to the question you asked.

How did you create the PDF of your ACad drawing?

What program did you use to create the PDFs.

I used CAD for many years, Generic Cadd to start then Visual Cadd and crossed with Acad every now and then, and never found creating a PDF of my drawings, mainly to share with others so they could not edit them, gave really good results. Line thicknesses were always lacking. Some to bold others not showing at all.

This comment was very unhelpful... Interior design/architecture students use AutoCAD and often plot their work onto pdfs to then import them on photoshop to render them. This is a common practice within the industry.
