Sketchup import Sectionplane etc., no go? Why

[CalypsoArt]

I do all my 2d in AC and my 3d in Sketchup. I use the section in SU and then export as dwg and dimension in AC. I though it might be better to import the whole SU model into AC and create the elevations there for dimensioning. However, it is not working for me.

I tried FSHOT, and I get "There are no solids or surfaces that can be projected"
I tried sectionplane and it shows up but doesn't hide the unwanted side. Am I doing something wrong or is the SU import the problem? It imports nicely and no visible errors.

Attached is test example. A model in SU imported into AC, and the sectionplane placement.

If you select the model and choose Properties what does it say for the object type?

[CalypsoArt]

The model is made up of blocks. I usually make all walls/parts as a separate group. In the export the become autocad blocks.

You will need to explode the blocks. As you should now be aware, those commands will do nothing on 3D blocks

Should have done your 3D in AutoCAD and used Flatshot to create all your 2D views. No need to jump back and forth between programs.

Are you saying it cannot be done?

I used to do 3d in AC until I discovered SU. The speed possible with SU for my work is impossible with AC. Even exporting elevations from SU, cleaning up if necessary, and then finishing is still way faster than modeling in AC.

No, I'm not saying that.

Did you follow any of the advice given re: your blocks?

[CalypsoArt]

I have exploded blocks and it does not seem to work. Though I don't know enough about it, I think it has to do with the AC tools working on solids and the SU model not being a solid.

[edwinprakoso]

Yup, AutoCAD only can FLATSHOT solids.
Unless sketchup can export the model to solid objects, then you can't do it in Acad.

I don't use Sketchup therefore please forgive my ignorance. There is no capability what-so-ever to dimension your sections in SU?
