I would love to suggest to all skillful developers to create a function which we can do interactive drawing between Autocad and Sketchup. The idea is that it might be so much productive if we can combine the work of 2d drawing of Autocad and 3d drawing of sketchup and make it works like the job of Revit. I don’t know if it is possible, but it would be great if it can be created.
This is now implemented in Trimble LayOut with the release of SketchUp Pro 2018. No need for AutoCAD. SketchUp and LayOut 2018 Release Notes say:
Scaled Vector Drawing
Now you can use LayOut’s vector illustration tools to draw in 2D at scale. Use your SketchUp model as a scale basis to create blocking details. Or create your own scaled illustration to add details not necessary in your 3D model: dashed lines or blocking, for instance. Re-set scales as you wish and your work will resize as necessary. As you would expect, your scaled drawings are fully supported by LayOut’s Dimension and Label tools.
SketchUp Pro has always had import and export with CAD using DWG and DXF formats.
In addition LayOut also has better DWG export these past few versions.
(Again, see SketchUp and LayOut 2018 Release Notes.)
If you are still using SketchUp Pro 2015, it is time you upgraded. (That version is now beyond support.)
And Trimble is not going to reduce SketchUp to a mere AutoCAD plugin !
Noone wants SketchUp to work like Revit ! However there are some parametric buildings extensions.
