Revit Error: Cannot make type: Curtain-Wall- Double Storefront

[Anonymous]

Adding mutton's to a storefront. Adding curtain grids, but finding it hard to evenly space and when placing it above a door the door is split and a error message is received. See attached images.

IMAGE 1: Shows result of placing curtain grid for the horizontal mutton (the mutton will be changed to 1" sq, but for some reason when placing the grid it automatically creates the 2.5x5 mullion?) Note how the temp dimensions from bottom up are center, center, out side face. I know how to snap temp dimensions to different points, but these will not snap to where I want to get it centered so I have to do some math and a lot slower.

IMAGE 2: Shows the vertical grid added for the mutton. Notice the door being split below and the error message, and again any temp dims will not snap to proper points to allow for quick even placement.

IMAGE 3: Shows mutton's placed above the door. I just deleted the door and added it back when finished, but notice how the mutton's are single lines. The mutton's are double lines when changing to wireframe and if I change the mutton's to any other mullion type they show up fine.

IMAGE 4: Show the mutton's as I want them to look, but as I said getting them center is slow and time consuming. I know there has to be an easier way. (I guess 3 images is max will send in separate forum question)

Any ideas?

Thanks,

Jeff

You are talking Mullions; not muntins. And you're really meaning Grid Lines and the difficulty is placing them. Am I right?  It's an acquired skill. With that said, only 1 mullion can be assigned to 1 Grid Line.  It you are seeing double mullions on a single Grid Line, I suspect the Visual Style of the view is set to Wireframe.

Spend some time and read through this tutorial to understand how grids work and how to add/remove mullions from a curtain wall.

I was using the 1" mullion to represent the muntin (I guess this is the correct spelling) this is only for a model not CD's (CD's are in autocad). What would the proper way to show a muntin be?

Yes I'm talking about the difficulty in placing gridlines for the mullions. I add the gridline using the one segment and yet it cuts through the door below even though I'm using the one segment option? Also not sure why temp dimensions will not snap to certain points in order evenly space the mullions.

I have been through all the tutorials that you linked, but will go through them again. I have watch a hour or so of video tutorial and have not found a solution yet.

Hi @Anonymous

Can you please share the door family to test on our end?

It looks like the family constraints are not satisfied which is why you receive this error.

Looking forward to your reply update.

I made a 5/8" square mullion profile for the muntin, but still cant figure out the temp dimension (or witness line as some call it) and why it wont change selection to even out spacing or the door error when adding gridline for muntin above.

It is the default Door-Curtain-Wall-Double-Storefront.rfa, but I attached it anyways.

What Curtain Wall Type are you using; one with a predefined layout (e.g. Storefront) or one without a predefined layout (e.g. Curtain Wall 1).  If you want to stagger grids the way your showing in your screenshot, don't use a CW Type with a predefined layout.  Maybe this is what's giving you headaches. 

...Hey! I was able to error out!  But, was able to workaround it and put your door into Storefront Type CW.  Order-of-operation thing.

UPDATE.

I feel your pain, @Anonymous. You’re not doing a darn thing wrong. What’s driving you nuts is some really buggy behavior by Revit – and it’s typical behavior, as far as I can tell. 

Revit is adding an extra mullion on it’s on.  It is this extra mullion that’s messing with your Double Door. 

Here’s the step-by-step for anyone to replicate:

1. Draw a 20 ft. x 20 ft. wall using the OOTB Curtain Wall: Storefront.
2. Unpin and Delete all the Horizontal Border 1 Type Mullions running along the base of the Wall. Should be 4 of them on a 20 linear foot wall.
3. On the Architectural tab, select “Curtain Grid”, and then select “One Segment” on the Placement contextual panel
4. Place a VERTICAL Segment in any/all of the panels above the bottom row of panels (as shown it the top screenshot). Note that with each segment placed, Revit not only creates a Vertical Grid/Mullion, but also creates a Horizontal Border 1 Type Mullion at the base of the wall.  And, if you happen to have a CW door (any CW door) placed below that Vertical Segment, Revit will spaz out and cough up the error shown in the bottom screenshot.

Revit gives you the error (delete the door and replace with a system panel) because when you add a grid, Revit automatically adds one mullion to the sill of the added cell, the result is you are having a non-rectangular cell and that errors any custom cell, which is your door in this case.

There is not much to be done about it, except fix it afterward by simply delete the added sill and replace the panel with the door again.  The errors can be minimized you plan ahead and place all the grids before adding doors.  Another way is don't assign any mullion type to the bottom frame under the curtain wall type, so that when you add a grid, no mullion will be added to the sill and the door will stay.
