Problem Importing 3D DWG

[dirumos]

Hi to all, and thanks for your futures answer and time.

I'm trying to import a 3D DWG to Sketchup. I get this message.

But then, when the model is displayed, it isn´t like the CAD view, see images bellow.

CAD Imported view in Sketchup

Model View in Civil3D

I've attached the DWG file.
https://www.dropbox.com/s/apfpvew2y7wfutl/Area%20Montaje%20Julio%202015.dwg?dl=0

I've reinstalled Sketchup, purge the DWG file before importing, I don't know what to do.

Please help me.

What Units was the original DWG in ?
What Units did you set in the Import Options ??

Hi TIG, thanks.

I'm using meters in both Civil and Sketchup.

The SKP's model-units is not relevant.
What Units did you choose in the "Options" settings under the DWG Importer's dialog [separate button on the dialog].
If it's left as the default 'inches' then 1m will be assumed to be 1" on import.
If the DWG's dimensions are small, then you might fall foul of SketchUp's 1/1000" tolerance limit ?
And some imported geometry might get corrupted...
E.G. 0.001m is 1mm, but 1/25.4 smaller when assumed to be in inches !

Hi TIG,

I'm importing using meters.

I tried to import your DWG using the Options > Units of Meters...
It imports.
There are issues. because the 9 groups that are created have their origins miles away from their geometry, so the appearance is weird and any orbiting etc is awful - jittery.

You have two choices.

Either make each group in turn into a component using the context-menu, then immediately change its axes to a sensible corner on its geometry [context-menu again]. After doing all 9 it'll be fine.

Or select the 9 groups and use 'Explode' [context-menu again] so their geometry is merged into one context, and their badly located origins are forgotten...

Another possibility would be to remake the forms entirely in SketchUp - its some simple 3d geometry for one [pushpull/offset/move] and an array-copy to make the 9...
