The AutoCAD team has spent the past year making many improvements and enhancements to the software. If you intend to import the DWG into Revit, keep in mind that Revit is not very impressed with very short lines.It’s a big day here at Autodesk! We’re excited to announce the launch of AutoCAD 2017 for Mac and AutoCAD LT 2017 for Mac. If you have any problems, feel free to comment and I will try and help you out. Open in AutoCAD and scale to correct size.Select the page in the next dialog (usually only 1), press OK, and then pick a place to save the DXF file.(I have found these settings to work quite well) mm -splineaspolyline -splineprecision 10 At the resulting PS to Edit dialog box, choose dxf_s, and add the following Driver options:.Go to ‘Edit’ and click on ‘Convert to vector format…’.Click on ‘Media’ and set the correct paper size.With your PDF open, take the following steps: GSView is usually located inĬ:Program Filesghostgumgsviewgsview32.exe Once you have installed them all, open a PDF file using GSView. Make your life easy and stick with the 32-bit version of everything. Is there any way you can get the base vector data, such as lines and arcs, out of the PDF and back into a DWG? Yes, there is – and it’s free.ĭownload and install each of the above tools. Sometimes you will have access to a PDF file, but not to the original DWG. The file sizes at each step look like this: From here, you can get to AutoCAD or Navisworks easily… Save as DXF (using Convert to Vector format).Open in GSView (requires Ghostscript and pstoedit).(this step makes the black and white image into lines and outlines) Untick: Smooth, Stack scans, Smooth corners and Optimize paths. Vectorize using Path – Trace Bitmap… Brightness steps, set to 2.Make your source file (PDF / Scan etc) into bitonal TIFF image (I use Bluebeam and Irfanview in the video, but you could easily save the PDF to image using GSView).Here’s how to do it, without Adobe Illustrator: But the below workflow takes it one step further – how to get any raster image into a vector format, using a few free tools. Take a hand sketch, for example – how can you get that into a format that can easily be used in AutoCAD or Revit? Some PDFs have vector information, which I have described how to access before. We often have to deal with data that hasn’t always “lived” in our CAD, BIM or Revit world. In Revit, L ink Point Cloud, by Sh ared Coordinates, and choose the un Indexed r aw PCG:.But PCG is a nice reli able cont a iner th at supports colours. For the ASC d at a above, on the import sett ings I used ‘ Adv anced’, and chose the text columns XYZRGB. Import ing the Point Cloud by Sh ared Coordinates You now h ave the right World coordinates, and a project grid rel ationship. L ink the DXF Centre- to-Centre (this is best w ay to de al with huge coordinates).Gett ing the right Sh ared Coordinates in Revit Here is the workflow th at worked for me… I tried gett ing the MG A Sh ared Coordinates right in Revit, and then l ink ing an RCP or RCS from Rec ap ‘by Sh ared Coordinates‘, but I didn’t h ave much joy. I also received a DXF file with the s ame World coordinates, and project rel ated gridl ines so I could rel ate the point cloud to our Revit models. Those XYZ v alues are Metres (or Meters if you are in US) in the MG A 94 coord in ate system. What Revit Wants: Using a DXF to Locate a Point Cloud in Revit with Very Large Coordinates GIS dxf, emeditor, point cloud, recap, Shared Coordinates No Comments Hope this helps you if you face a similar problem □ Now you can Acquire Coordinates from the original DXF and you will have reinstated the ‘world coordinates’, but the Revit point cloud rendering engine is now much happier.You may need to temporarily neutralize coordinates ( here or here), and….Link in the original DXF and align it with the modified temporary DWG we were using.Everything lines up now that the large coordinate shift error has been avoided!.Link the Point Cloud RCP By Shared Coordinates.
