i understand that an iso isn't going to have true dimensions, but at the present moment we draw our iso's in autocad with true dimensions, which are later referenced in the detail drawings. We are trying to see if sketchup would be a more beneficial program to use in drawing our iso's, the only problem is that we would still need to be able to reference the iso for true dimensions when drawing the details. I didn't know if there was a way to auto scale the sketchup drawing so it would be the correct scale when you place the 2D into AutoCAD. thank you all for your responses. any other ideas are still welcome.

I have done all of the above, parallel projection, standard view-iso, and the dimensions - i tried both arch 2D and arch 3D and there was no difference. I don't understand why it's not working correctly either. any other suggestions?

I am trying to produce our ISO's in sketchup and then transfer them into AutoCAD as a 2D graphic, I can successfully export the file and open it and the file is fully functional, but the drawing does not have the correct dimensions. I have the correct scale in the options dialog box when I'm exporting, but the sizes are off. I have tried to do this with a front view and that produced the correct dimensions, so it seems that Sketchup only takes an image of the 3D model to send into AutoCAD. I am wondering if anyone knows if it is possible to bring an ISO from sketchup into AutoCAD with the correct dimensions?
