Revit to PDF conversion

[D23124962]

Is there way to import raster images/ sheets into Autocad. I have a PDF sheet created in revit that has views with shadows. Looking to transfer that across into CAD and then change the lineweights from there

Are you having issues with the  _importpdf command?   See options below. It might be easier to import multiple times and filter the data.

yes how do i import the PDF so that it retains the drawing views

[David_W_Koch]

If you are generating a raster PDF (due to those shadows), you will be able to link it into AutoCAD, but you will not be able to import vector geometry from it.  You would need to import vector geometry in order to assign lineweights.

what would be the process to this sorry im not really familiar with Autocad.

Use the ATTACH command or the IMAGEATTACH command.

and how are lineweights changed from there

There are no lineweights in an image, just pixels. What are you trying to do? Maybe there's a better way to get information from Revit.

It would be more helpful if you posted a sample pdf to see how it is organized (layers etc).. Also, you should be making two pdfs.

1. vector linework

2. shadows only.

The vector linework can be converted through the import function.  Once the linework is imported, you can assign layers and control your linweights through the layer palette. Lineweights can be controlled by either linweight property (1), color (2) or a combination of both.  

This will depend on whether you opt for the stb or ctb.  

I do not recommend this method, however, lineweights can also be applied to individual objects using the property palette.

Hi Ed,

On Revit you can only reduce the lineweights up to a certain point, when the sheet is printed I still get the bit of heaviness on some of the lines. What I am trying to do is reduce the lineweights to be as thin as possible by exporting the revit drawing into CAD format and setting the thin lines in CAD. I've been told that this is possible, just not aware of the process

[D23124962]

There's a CAD function to import PDF and reduce the lineweights through the plot print system I believe. I'm attempting to do it that way instead of going through the layers individually; is there a step by step process for this is it possible?

[R_Tweed]

You would need to upload a dwg for step by step instruction.

Your layer palette will look less cluttered if you work from model space.

Make sure you do not have object overrides. Object properties would be bylayer as shown below.

Post a screen shot of your plotting parameters for output. the sample below is based on a ctb plot style.

[R_Tweed]

Save your ctb file to another name - "elevation" and modify color 7 as shown.

[D23124962]

yes. does this apply to unique hatch patterns as well, like the foreground of a cut section or it selects any element that shares the same colour. 

[R_Tweed]

Each virtual pen is matched to a color.  Whatever the object color, the appropriate virtual pen will be used.  If you want to fade out the foreground, one way would be to change the objects transparency setting.  This will fade the linework while maintaining it's lineweight. That can be applied as a property override. If you want to print certain things in a specific color, give that layer a true color value. rgb 209,209,209 will print a shade of grey.

Turn on lineweights to see the effect.  or use command LWDISPLAY
