Object style - Subcategories

[mairh_tsek]

Hello,

I am a little bit new in Revit and I have the following question:

I want to create new sub-categories in the object style! I have found the way to do this..my problem is that I don't know how I will 'link' these sub-category with the part (lines) of the element that I want to change.

For example I have a wall and I want to add a sub-category to change the upper line....so how I will #link# the apper line with the settings that I have defined in the sub-category that I created?

I hope to make sense

Thank you in advance!

Hi @mairh_tsek

New subcategories will apply to the user modeled Elements defined under the parent category...you cannot change an element of a system family to a subcategory you created.

These are more useful when modeling elements in Family Editor than in Project environment

Hi @RDAOU ,

thank you for your answer, ' parent category'?

[RDAOU]

The original Categor...hence: Parent that makes the Subcategories the children 🙂

@RDAOU is right.

Here is a picture to show the relationship:

the category is parent to the subcategory.

The subcategory is chid. 

Child and parent describe a relationship,

Category and subcategory describe a hierarchy

About walls, as you cannot edit subparts of a wall (apart from cornices and sweeps), you cannot assignthe them different subcategories.

The only way to do that with a wall is to model one in-place.

Which is not a good workflow by the way.

About subcategories, you mus know that:

As Rdaou has said, they are better used in Families. Here are a few rules though:

1. If you import a family that includes a new subcategory, the subcategory will be created in your project automatically. It will have the same properties as the ones in the family.
2. If you import the subcategory again, its properties will not change. The project gets priority over the properties of the subcategory.
3. Be careful to name subcategories exactly the same in different families in order to avoid multiple and annoying subcategories in the main project.

Hope this helps,

Cheers,

François

That was the reason why I couldn't create subcategory in a wall!

Ok, thank you very much!
