@swabygw , I think I’m going through the same issues as you do. I contacted the support for it, but they friendly asked me to post in the forum. Ok, if the forum can help me, I’m fine, but I paid +130 EUR incl. VAT for SketchUp Shop specially to be able to export to DXF, and there seems something not working.
I made the below drawing. As you can see it is 257 mm wide and 89 mm high.
Exactly like mentioned above, I’m using parallel projection, and topview.
When I use Export/DXF/2D, I select 1:1 scale. Honestly, I have no clue where the dimensions come from (574.51 and -301.62 - this is even not a ratio of my drawing)
When I import the result in “DWG TrueView 2018”, and I measure the width, then it shows 290.2062 mm.
I played with exporting a couple of days ago, and it always gives me the same (wrong) dimensions in DWG TrueView.
- I’m using “app.sketchup.com”
- I tried it in Google Chrome (not via de app), but exporting gave same result
- I also exported as DWG/2D, but the same (wrong) dimensions are shown
I have attached both skp file as exported dxf.
My solution so far: I export as DXF with wrong dimensions (I have not much other choice) and import it in the free tool LibreCAD ( LibreCAD - Free Open Source 2D CAD ). I calculate the scaling factor (257/290.2062 = 0.885577), and use this to scale the drawing in LibreCAD. Then I just save it. Although this is an intermediate step, it works as a charm!
