Hopefully you understand how pen weights work and how to create Subcategories
to control visibility of the objects you wish to create. If not look for
my other tutorial on pen weights and Revit. This tutorial will be a quick
overview of pen weight control in Families. There is no difference with
pen weights between Families and Projects, other than there are additional
categories to consider, such as is this a projection model line, or a
cut model line. This tutorial will use a Generic Wall Based Model for
an example.
Begin your new family. Select File? New?Family?Generic Wall Based Model
(should be under the Imperial or Metric Template file – depending
on your default units), then select OK to start a blank family. Select
Model Lines from the side bar, and note the type of lines that are available
to you – There are 3 – <Invisible lines>, Generic Models
[cut], and Generic Models [Projection}.
From the Pull downs across the top select Settings?Object Styles and we
see that there are two categories for this Family type we have selected,
Generic and Wall. (Figure 1)
Figure 1.
We can create new Subcategories of either of these two categories, but
cannot create a new Category. This is only important from the stand point
of visibility control in your project, as you will see. Select each of
the Categories and create some new subcategories under each. I created
a “cut” and “projection” subcategory as you see
in Figure 2, and a “details” subcategory under walls.
Figure 2.
Hit OK to save these Styles.
Now select Model lines again from the Side Bar and you see that in addition
to the original model line types there has been created a cut and projection
line type for each of the subcategories that we just created – AHA!!.
This is where you control the line weight with your model lines in family.
Let’s create a void in a wall for our example. [A side note. At
this time this tutorial does not use reference planes to create the following
void. It will be MUCH easier to create the model lines WITH reference
planes that you can snap to. In respect to memory requirements for this
site, I have elected to not go into the creation of reference planes for
this exercise. If you need help with that just email me]
Go the Plan reference view, and select the Placement side of the wall
and drag the reference plan Wall Edge out beyond the end of the wall.
– (You don’t have to, just helps me remember it is there and
find out what it is named. )
