Wall Componant Modifications?

[m_cahoon14336]

I have a wall 24' tall constructed of 12" cmu, 1 1/2" rigid insulation, 1" air space and 3 5/8" brick veneer. The cmu component needs to be exposed up to 16' a.f.f.. The rigid insulation, air space, and brick veneer will start at 16' a.f.f. and continue up to the top of the wall. How do I create this wall type? In reality, the brick will be supported by a steel angle, but I do not have to show it in the wall type. I thought I had a pretty good grip on wall components, but I cannot seam to figure this one out.

One method would be to use a bottom offset for the Brick, insulation layers. ( Unlock these layers from the Edit Wall structure dialog )

Another method would be to stack two wall types. CMU bottom and complex wall top.

[Scott D Davis]

Compund walls, in order to offset the layers, you have to unlock the layers in the properties dialog of the wall. Right click on the wall, the go to Properties. In the properties box, click the Edit/New Button, then the Edit button next to the Structure catagory. You should see something like the attached image. (you may have to hit Preview to see the wall view) At the bottom of the view fly-out, there is a view pull-down, change that to Section. Zoom in to the bottom of the wall (scroll wheel or right-click>Zoom) then click the Modify button in the "modify Vertical Structure" area of the dialog. Then click on the bottom line of the Brick layer, a lock icon will appear. Unlock it. Do this for the Air and Rigid layers. Leave the CMU layer locked. Click ok to get out of all dialog boxes.

Now right click on that wall in your model, go to Properties, and change the Bottom Extension Distance to 16'-0". Click ok to get out of all dialogs. Cut a section though your wall, and it should have the brick, air, and insul. layers 16'-0" off the ground. See attached image. You could also adjust this in section on the wall by hovering over the horizontal line that makes up the bottom of the brick/air/insul layer, TAb until just the line highlights, then click and drag upward. You can tie a diemnsion to it if you want, so now the offset can be controlled dimesionally.

beegee, Can you walk me thru this? I have looked and looked at the edit wall structure dialog, and cannot figure out how to lock or unlock the layers. I am not finding anything that references "bottom offset".

EDIT : Scott D has done that above. Thanks Scott. bg.

[m_cahoon14336]

Thanks Scott and Beegee. With your instructions, I've finally figured it out.

Scott, Beegee, I still have a problem here. I cannot seam to get the two cmu components to clean-up. I need the brick veneer to continue across th top, but I also need the cmu wall components to join below. Any ideas on this? Thanks

[Scott D Davis]

This was a tricky one. I got it to work by making the wall intersection 90 degrees instead of a "T". It cleans up like that. Then copy the compound wall from the "L" and make the condition a "T". Make sense? You end up with the top part of the T being two compound wall segments, and a third 8" CMU segment makes up the tail of the T.

A little different solution than Scotts. Note the cleanup file is a Word Doc file, zipped and then renamed to a rvt file to get it to post. To use it, rename it to a zip file, then unzip the file. This keeps your main wall (brick and block) as one continuous wall.

Yep - tried that, but exceeded the size limit by a couple pounds - hope my workaround's not a problem - Word doc limited to 500k, zip to 1M. Tried both...Just trying to help. the word doc was over 1M zipped....

Thanks for the help Scott and Skisouth. I tried your approach Skisouth and it worked for me. Now I can move this project forward! Some of these wall conditions can be tricky.

[Scott D Davis]

Skisouth, would you please write a quick description of the steps you took. It will help others figure out what you did.

The illustrated version is in the word doc posted, here is the text:


Or you can use a small wall, joining it to these other two walls.Once you’ve created this wall, select Tools- Edit Wall Joins and disallow wall joins. Then Tools – Join Geometry, Multiple Joins (top of drawing screen) and select the small wall you just created and both of the other walls. Now you plan looks like this. Which looks great, but I messed up and built too tall of a wall so that it cuts the upper wall. So now to edit the profile of the newly created infill wall. Select the wall (here I edited in 3d) locking it to the shorter wall with the result that is desired, but note that the block pattern will show the jointing a little differently than the other short wall – I’ll let you solve that problem. It is easily done.

I have a problem with that whole method...and maybe it's just me...so someone correct me if I'm doing it wrong. I tried it once and got so frustrated I ended up going to the "stacked walls" method (and also using the "edit cut profile" command in my sections).
What was happening was that if I changed the base (or top) offset, I would get an error message...something to the effect that it couldn't complete a wall sweep (I'm not sure of the wording since this was a while back that it happened) and I had to cancel the change and either fudge the results or delete the whole mess and start fresh walls.
To me, AutoDesk has A LOT of work to do in the area of editing compound walls to make it A) more user friendly (I still can't make heads or tails out of some of the editing options - half the time I try to change something, nothing happens), and B) able to handle walls that vary in thickness and materials vertically without the user having to stack, cheat with drafting tools or update multiple items manually to conform to the design intent.
