I have tried to import a dwg wall-roof section I already have into my Revit 2011 in a section view to use as an underlay but although it shows up in my vis/graph overides it will not show up in my wall section is there a way to bring it straight into my section easy. Its hard enough to move over from my ACA into Revit as it is without throwing away all my years of details aswell!!

A CAD DWG can be imported into any view but there is a difference between it being a detail import or a model import. 

If you import a DWG into a view and do not check the "current view only" box, then the CAD linework is basically 3D linework and is placed on the workplane of the view.  If you do check the box, then the linework is 2D and only visible in the current view (if not hidden by model elements).

Your question suggests that you did not check the box (and have probably made a mistake).  The reason why you can't see the CAD is that you are not looking at the same work plane or/and are not in the area where the CAD is.   If this is CAD detail work, then you should be checking the box.

I suggest you learn how to "revitize" your legacy CAD details.

Thanks for your input, but I still cannot get the detail into the view (section) & cannot find it in my drawing. It shows up as being there in my - vis/graph overrides - Imported Categories - along with 3 others that I have tried to import but have failed to see. This last time I ticked the box you suggested "current view only" but it did not appear. I also moved the model geometry to see if that was hiding it but could not see it.

Hey thanks again Hub

I found out what my problem (mistake) was!! The cad dwg had a 0,0,0 location a loooong way off the 2d detail.

So finding it in my Revit view was hard, but now I have a better understanding. Often its just one little detail that is difficult to over come, now as you said I will have to put some time into Revitising my volumious cad detailing, finding the time oh thats gonna be hard.

Guys, sorry for bring this back but I'm having almost the same problem with linking in my dwg. However, unlike the OP, my cad file has everything at the correct coordinates (nothing at 0,0,0) I can link it in but can't see it(!) Anything else I can try?

Did you try a 3D view with a zoom E.  If nothing shows at all, then everyting is too small to be seen.  Window just the upper area then just the lower area to see what is in those locations.

Thank you WWHub. However, I zoomed extent and still only saw other things in my model as usual. Anything other idea please?
