vasilikit4 0 Posted February 18 Share Posted February 18 Hi, i downloaded sketchup 2017 in order to open a sketchup file and export it as .dwg . Then i inserted the dwg file in autocad 2017 and tried to unite it with the drawing i had prepared. But they do not unite.. what's going wrong? Quote Link to post Share on other sites
steven-g 169 Posted February 18 Share Posted February 18 It would help if you explained what uniting is in this case, are you actually trying to union solids or do you mean something else? What are the objects? What commands are you using? what does the command line say if there are error messages? Quote Link to post Share on other sites
ReMark 135 Posted February 18 Share Posted February 18 Do you mean you are trying to "UNION" the objects? Are they 3D solids? Quote Link to post Share on other sites

steven-g 169 Posted February 20 Share Posted February 20 If you select the items what does the properties palette tell you these items are? Very possibly not solids. Is it possible to post the .dwg file here so someone could check for any problems. Quote Link to post Share on other sites
ReMark 135 Posted February 21 Share Posted February 21 In order to import the Sketchup object into AutoCAD it had to have been properly exported as a 3D Model. Is this what you did? You also must specify the version of AutoCAD you would like to use to open the file. In SketchUp, select File > Export > 3D Model. The Export Model dialog box appears.

f700es 121 Posted February 21 Share Posted February 21 There is also the free SketchUp import app for AutoCAD https://apps.autodesk.com/ACD/en/Detail/Index?id=5947739119625287617&appLang=en&os=Win32_64 Quote Link to post Share on other sites

As Steven-g mentioned, check the properties of the imported objects. They are most likely meshes, not solids. 1 Quote Link to post Share on other sites
f700es 121 Posted February 22 Share Posted February 22 Correct Cad64. SU is a surface modeler so all of it items will be surfaces Here is a screen shot of a comparison between AutoCAD's SU import and a SketchUp dwg export... Quote Link to post Share on other sites
