PIT in the palm of my hand (families, shared parameters, schedules, tags)

The SQL modified date (31 Oct 2024) differs from the publish date (21 Jan 2024). The publish date is unchanged. The body refers to Revit 2016.

Hey. It's already September 2017. The year's almost gone... and so is another birthday.

This time, as the title says, let's get PIT into the palm of our hand.

On a job site, there are times you just want pits to be easier to manage. I don't know how everyone else does it.

I want to share the way I manage them.

I will make a family that is easy to manage, apply shared parameters, connect it to a schedule, and tag it as well.

(Note: you can download the sample files at the bottom.)

What I want is to use shared parameters so that the PIT size, schedule, and tag stay linked.

It ends up like this.

The information I want to manage is:

  • The PIT Mark value

  • Width / length / depth

  • Top Level (T.L) / Invert Level (I.L)

Let's make the family first.

I had a video from an older study session, so I edited that. Unfortunately the sound was not recorded.

  1. Making the PIT family

The PIT family is done.

Now let's apply shared parameters.

  1. Applying shared parameters

Top Level is given on site. Think of it as the reference level for that floor.

Here, Top Level and Invert Level both come from site, so I built the family so the model updates when those two values are entered.

Enter Shared_T.L and Shared_I.L, and Shared_Depth is calculated with this formula:

[Shared_Depth = Shared_T.L - Shared_I.L + Offset fr I.L]

If you want a different driver, you can adapt this.

The reason for shared parameters is so the project file can schedule and tag them.

Now let's make a schedule.

  1. Schedule

Because the schedule uses shared parameters, changing a value in the schedule updates the model, and changing the model updates the schedule.

Now tagging.

  1. Tagging

Now the tag, the schedule, and the model stay linked and update on their own.

Managing pits this way has several advantages.

  • No mismatch between the tag, the schedule, and the model size.

  • Revisions are very, very fast.

  • You can produce an accurate schedule whenever you need one.

Closing.

If you adapt this, you can use it for more than pits.

Let's go!

Update: I am uploading sample files. Use them freely if you want to study.
