Anyone has experience with exporting to dwg? Can't get it to work properly.

I need to export drawings to dwg for an outside associate, they're not tech savvy at all so I have to come up with the least painful, full-proof way to get it done. But none of the options work 100%, or I'm doing something wrong on either Revit or Autocad end.

Ideally it would be like a standard dwg, layers with different colors, and a plot style based on layer colors.

 

There are three options in export dialog box for colors, "Index color", "Specified in object styles" and "Specified in view". I'm exporting sheets.

 

First option (Index color)

seems like the one that should be used, but that one has the most issues.

You get a "pcp" file with it which should act as some sort of plot style file (right?). I tried using it, there's a "New" option in Autocad where you can "import" from PCP file, but that didn't work at all. All the colors in generated plotstyle are just the same as colors of the layers, instead of black or gray. And thickness of all layers is the same.

I also tried the PCINWIZARD command in Autocad, with even worse results. Colors still remain unchanged and text somehow gets messed up.

Although not that important, but for some reason Revit, seemingly randomly, exports identical objects on different layers. These two columns are the same family, same type, have the same material, same base level, same top level, same offsets... Yet, they end up on different layers?

Second option (Specified in object styles)

is even worse. All layers are white in Autocad (i.e. black when plotted), but more importantly, some hatches just, simply aren't exported.

Left Revit, right Autocad:

Third option (Specified in view)

is, somewhat, best. Line thickness is as it should be, colors are preserved and all the hatching is exported.

The only downside is that here to all layers end up being white in Autocad, making it difficult to work with.

Here Revit also has issues with the same elements. Again, the same columns with everything about them the same, yet they have different thickness. These two are even placed in the same wall type. But again, this is not all that important.

So, am I doing something wrong, or is this it ?

Should I just manually create an old fashioned plot style and send it with the first option dwg, or am I doing something wrong and there is a more automated way?

Question about the column? Are those columns join geometry with the wall or overlapping with the wall? Since Revit doesn't have a draworder for model objects, a lot of these mishaps will occur. It is annoying and very difficult to fix. Often I just leave the CAD as is and give it to a consultant who will only use it as their background CAD.

Overlapped, just plopped in there. There is way too many columns and beams to keep track and join everything to walls and floors. I leave joining for the very end, and then do it just in sections where they're actually visible.

This results in slightly inaccurate material takeoff regarding volume of wall blocks which is mildly infuriating, but considering that before Revit we used to increase the quantities by 5-10% anyway, it's within tolerance.

 

Back on topic, those different layers don't bother me that much, they'll have the same color and thickness in plot style so it's not a big deal.

 

Seems like manually creating plot styles will be the way.

Did you try exporting from a view that is set-up with the colors as desired?

 

Did you look at the export layer settings?

Yes, I'm exporting sheets which in Revit are black and gray.

Yes, there you set on which layers will Revit elements be exported, and what color will those layers be. Right? I have no issues with it, with first option everything lands on proper layers (mostly). But when using the pcp file that Revit provides in Autocad, results are as seen in the first post.
