showing lintels/CMU wall openings

[cmbyrd77]

Does anyone know how to show CMU wall openings/lintels on a framing plan without losing the rest of the framing above? I am trying to show steel lintels and also show door/window openings so i can draw a detail line in representing a CMU lintel. The problem is that when I change my cut plane to that low I lose all my framing below.

Another question I have is when I have joist extension I have to keep the plan detail level set to medium or fine for them to show up. Typically a framing plan would not show that much detail. Also the problem with that is you also lose your moment connection callouts. Is there something I'm doing wrong. The only fix I know of is to change the detail level to course and then just draw in detail lines.

Thanks for the help,

with regards to the joist extension in course detail level. You have to edit the family to make a symbolic line appear when a joist extension is applied to the family

In regards to the lintel question, I am confused as to the elevations you are using for your cut plane. please provide additional info showing how you are setting up the view ranges and cut plane.

As far as making the symbolic line for the joist extension, could you give me a little guidance on that, I'm not too familiar with editing jar joist families.

As far as for the lintel question goes, I have roof framing at 18'-0" and I have an opening below at 8'-0". I want to be able to show the opening in the CMU as well as the roof framing. Typically we would have a our cut plane at 1'-0" on the framing plan, but in order for me to show the opening I have to have it at somewhere just under (-)10'-0". Well when I do that the roof framing disappears.

Thanks so much.

You should be able to change the bottom in the view depth to just below your lintel/opening heights and it should show your openings and lintels. Thats right, why not actually model them. If there is alot of them you could schedule them.

Also, I've got the bar, and angle joists made and will upload them. The only thing that isint great with them is that they no longer create the cut back once you modify them but you can extend them and the course model line extends and corresponds in the family.

You must be working in 2011. We are still using 2010 so I can't open the family.

I do have the steel lintels model just because the arch's wanted them, but I will have a schedule. Typically we will just draw a detail line through the opening and give it a L-1, L-2, etc. tag. The only way it is showing the openings is if I change the cut plane, and once I do that I lose all my framing above.

First attached is a angle web k series joist with extended ends that I created for Revit 2009.
First use the beam end join tool to extend the model line out to the end of joist seat.
Then modify the joist extension instance parameters.

if you modify the family name to remove the words extended end it will work with the out of the box revit family parameter file.

Secondly, if it not an issue change the model graphics style to wireframe from hidden.
All hidden lines within the view range will appear.

We make the walls transparent in that view and the lintels will show. Or, use two views and stack them on the sheet (they will snap in place). We use the latter method as it's cleaner and dependent views created from these are used elsewhere as well.

Thank you very much. So is that just a matter of copying to clipboard and paste aligning?

[Jmickledesign]

No I believe what he means is when you put your roof plan on the sheet, you then put another plan view on that same sheet right on top of it. Also, now that I think about it you could probably click on the underlay option on the view properties to get them to show up also.

we created a family with a masking region and a symbolic line representing the lintel. i then change the view range to see all my openings and place my "lintel family" then change the view range back to the original eleavtions. the only draw back is that if your openings move you have to go and move them individually

When you are creating lintels, can you "attach" them to the opening so that if the size of the opening changes (or if the opening gets moved slightly) the lintel adjusts accordingly?

[Galadriel]

yes, locking them to the wall

When you are creating lintels, can you "attach" them to the opening so that if the size of the opening changes (or if the opening gets moved slightly) the lintel adjusts accordingly?

We embedded a 'header' in our opening that adjusts based on the header/lintel size in depth width and also adjusts in length based on the opening size. We added a couple more embedded families to control trimmer and king studs as well as a flag that allows specific control over the 'overlap' when it's a lintel. It's in the family type Structural Framing and it's embedded into the families as a Shared Parameter. This has allowed us to select the opening and choose the header/lintel from a drop down (WH1, ML2, etc) for each opening...all in a schedule so we don't have to hunt down a model element to change it. It has worked very well for us.

For lintels, you can just use the beam tool. We have created our own lintel families but you can just use the out of the box steel framing members for them too. You can duplicate the beam type (rename it like L1) and then give it a type mark of L1 and schedule by type mark. You want to draw the lintel in the plan you want it to show up in. Then to set the elevation you want to change the z-direction justification to "other" and then use the Z-direction offset value, that way it doesnt move itself away from the reference level because the start and end offsets are still at 0'-0"
