I am trying to figure out how I can modify or create a CMU wall that displays a more accurate picture when cut by a section marker.

currently it just shows a rectangular box with angled hatching, and I would like for it to look like the image attached (I was able to modify the CMU detail component.

is there a way to do this? can anyone help?

Cheers!

 WWHUB I sensed a bit of sarcasm on your reply (I am hoping it wasn't that).  If you read it properly you would understand my question better. I Understand the reapeting detail concept and the image you see is exactly that. What I am trying to do (if it can be done) is make CMU wall look like this by just cutting it, no adding a repeating detail to it. In other words, changing the section profile of the wall.

I am trying ot do this so that when I cut a section there is les detailing to do.

If anyone can help it owuld be awesome, if not? oh well

Well, if you don't want to use the "repeating detail" and you want that in 3D, i think you must create that with "Curtain walls"...

See an example...

There was no sarcasm meant at all - it just didn't look like you understood how Revit works.  

Revit and our systems are not capable of doing what you want.  We just can't model everything!   Revit will model and show you the external faces of objects but beyond that, it expects you to add detail in the higher detail views.  That's why they give us the repeating detail tool.

It really is foolish to have every component everywhere.  With just the faces modeled, I have exterior renderings taking 6-8 hours on a good system.  I can't imagine what it would take if you start adding individual components for items that can be represented by one face.

It seems to me that you could get that level of detail in your wall section without having to add detail components. I am running into some of the same questions with my CMU veneer.

I think WWHub is under the assumption you want to add more geometry to your walls and i don't think you need to to get your desired result. You would still have your same 4 wall faces (man i hate extra polygons), just the pattern in the wall section would change. If you are able to create a model pattern of your CMU section cut then you could apply that to your wall material and it would show up everywhere your CMU was cut. I think the only limitation that you run into is being able to set your pattern start point like you can on an elevation (not sure why you can do one and not the other).

A similiar situation would be a section cut perpendicular to your roof framing, have your core structure be 9 1/4" for example and have a material applied with a section pattern showing your 2x10 framing @ 16" o.c. You would then just have to set the section pattern to start in one of the corners. The only problem with this would be when your section is cut parrallel to your framing, i guess you would have the same issue with your wall (although more unlikely).

Just throwing some ideas out there, I understand where VANREVIT is coming from. I would like some more of my section information to be more automatic, probably because i have only been using Revit for 8 months now (ArchiCAD and ADT before) and am not as disciplined in the ways of Revit as WWHub or Typhoon might be. Everything seems like it should show up automagically in Revit but as WWHub said before "We just can't model everything"....not yet at least.

Definately good to start thinking outside of the box on some of these things, maybe there could be a section cut pattern that would know when to show parrallel or perpindicular and somehow read that information from the roof slope or the wall justification. And maybe someday pigs would fly.
