Creating custom MullionType with RevitAPI

[Anonymous]

I  am working on some ways to automate the creation of curtain wall types in a project.

To do this I would like to first automate the creation of custom MullionTypes by  iterating through the family types within a custom Profile family and creating generating a new MullionType for each. 

Example steps:

1. Import profile_family with 3 types:

• intermediate_mullion
• post_mullion
• doorframe_mullion

2. Get list of symbols from profile_family

3. For each symbol, create a MullionType under the Rectangular Mullion familly

4. Create new WallType of kind Curtain or duplicate an existing. Rename. 

5. Set new walltype parameters, use the the previously created MullionTypes in setting the Border1,Border2, and Interior parameters. 

Im stuck though on how one would create a MullionType with the custom profiles. Using RevitLookup I cannot see where  the Profile can be set. Within the ParameterSet, the "Profile" parameter doesn't provide access.

Help!

Dear Brian,

Thank you for your query and the illuminating RevitLookup screen snapshot.

Why do you say that the image shows that the Profile parameter does not provide access?

As far as I can tell from your screen snapshot, it is read-write, and its storage type is ElementId.

Therefore, all you need to do is determine the desired profile element id 'x' and use the built-in parameter definition 'bip' (obtain it from the Profile > Definition > Built-in parameter enumeration value) to set it like this:

  Element mullion = ...
  mullion.GetParameter(bip).Set(x);

I hope this helps.

Best regards,

Jeremy

Hi Jeremy! 

Many thanks for your response. So quick! Initially had some issues but just worked it out.

Thanks for your help! Was as you said; I am not sure why I was not initially getting a null for the value of the "Profile" parameter. Perhaps I was too tired to notice my earlier mistake, working today! Excited.

I found the answer,  It's because I forgot to use Transaction Start & Commit...

Thanks for this thread anyway 😛

Hi, sorry for replying to an old post,

but I couldn't find any source in a similar topic except this one 😞

I have the same question when I tried to set the profile parameter

I'm trying to use both ElementID or ValueString to change the profile,

but none of them works,

am I missing something?

or if the MullionType only works in a Family Editor Document?

Thanks in advance :]

Well, the StorageType is shown as ElementId in your screen snapshot, so that is definitely the data type you have to use.

Set different mullion types manually through the UI and observe the different effects.

Then, do the same using the API, and you should achieve the same effect.
