advanced rendering for AutoCAD

will give it a short
thanks
Render in nXt, do hidden line removal in AutoCAD, plot it to bitmap, do the rest in PhotoGIMP (overlay the HLR over the rendering), if you do not want to do that in Sketchup :)
Please could you give a step by step instructions?
1. Render in nXt (got that part)
2. do hidden line removal in AutoCAD (not sure what you mean here)
3. plot it to bitmap (first importing the rendered shot as raster image I believe)
4. do the rest in PhotoGIMP (overlay the HLR over the rendering) What is HLR
I'll give it a try...
1. Hope so :)
2/3. Probably means plot your ACAD view with Hidden Lines to a file. I prefer PDF as I can get the best quality and resolution.
4. Save the plot (pdf or bitmap) to file. in your editor (I use Photoshop and don't know Gimp very well), overlay the line work file over the render. If your linework file is black/white, try using a blend mode like overlay or multiply to make the white background transparent. Otherwise mask out the white part of the line file so that only the lines are opaque.
can you help with screen shots of the process?
The confusion starts at the print in *.pdf or *.png autocad part.
You need to create a file (jpg, png, pdf, whatever) that you can overlay over your render. You need to export your model to a format that can be imported into your photo editor. Acad has a couple bitmap and vector formats it can export to, but not very high resolution (or I haven't learned how). I just plot to a file.
At my job I have Adobe Acrobat and at home I use PDF Creator, but the process is basically the same. Save your view you rendered and setup a plot file sized similar to your render. in the plot dialog, you can set it to hide mode so you only get the visible edges and save.
Not sure about gimp, but photoshop opens a pdf with the "paper" transparent. Just the lines, overlay on top of your render.
