Globally Hide Specific Levels w/ Referencing Spot Elevations

May 5, 2013

The Need: 

When working on a large project I needed to create a level that allowed me to set a base level of 0’-0” for a stair tower that did not share the same level as the ground floor of the building.  I was then going to provide spot elevations from this 0-0 reference for each landing and level as a means to providing fabrication reference points for the overall 6 story stair assembly.

The Problem:

In a drawing set which contained 100’s of drawings that would inherit the new level (that no one wanted to see) let alone have to hide in every drawing where it appeared, I needed a way to control a single level’s visibility throughout the project.  In my case I had two separate stair towers so I needed to hide two independent levels.  I needed these levels to give my spot elevations for the towers a base reference.

The Caveat:

You only get to utilize this solution if you have created Worksets for a Central project file.  For those one man firms not using a central file approach it’s probably not such a big deal to hide the level in the few drawings where they will appear.

The Solution:

CREATING THE CENTRAL FILE –  In Revit

  1. Go to the Collaborate Tab and select Worksets to the far left to enable worksharing.
  2. At the Worksets Control Window create a new Workset, mine was named Hidden Levels.  It’s important to uncheck the “Visible in All Views” box where you enter the new Workset’s name.
  3. At the prompt to make the Workset Active select “No”

CREATE THE LEVEL YOU INTEND TO HIDE.

CONTROLLING THE SPOT ELEVATIONS:

  1. It’s important to use the spot elevation type that is using a “relative” reference.
  2. Spot elevations are under the “Annotate” Tab
  3. Once you select the spot elevation make sure you are using the Target (Relative) type which shows up in the properties dialog at the top. If not selected go to the drop down arrow to the right and select it from the drop down list.
  4. Place the spot elevations as desired.  The spot elevations will reference to the “Current Level” by default.
  5. Select the spot elevation you want to reference to the   level you are going to hide.  In this case it will be the “stair base elev ref.” then go to the “Relative Base” drop down shown in the image below.  Note: I have spot elevations referenced to Level 1 and the Stair Base Elev. Ref. as well in the plan level 1 view.
  6. Revit-Relative Spot Elev
  7. You can hide the level at any time and without affecting the ability to select the hidden level in the Relative Base drop down.

HIDING THE LEVEL:

  1. You need to assign the level to the “Hidden Levels” workset you’ve already created above. Select the level to be hidden and in the Properties dialog set the workset to “Hidden Levels”
  2. Revit-Hide Level Step 1
  3.  Now in the visibility graphics control interface (Key stroke “vg”) go to the Worksets tab and at the far right drop down for the “Hidden Levels” select hide.  As shown in the image below the level disappears globally throughout the project but the spot elevations retain their reference to the hidden level.
  4. Revit-Hide Level Step 2

Now all those team members won’t be screaming at you when you add that extra level.

Enjoy

Custom Railing Connections in 10 steps.

October 20, 2010

I was working on a stair and discovered this nice procedural on creating custom railing connections.  I used it primarily for the end post conditions with the following results.

Here are the steps, should we lose the link.  Much thanks to Luke Johnson of Australia for posting this.

  1. Create a 3D view with section box around the connection you would like to resolve
  2. Export this 3D view to a DWG file.
  3. Create a new Generic Model family.
  4. Import the 3D DWG.
  5. Using the context you have now imported, model the rest of the baluster / railing connection.  I recommend that you use Reference Lines and then create Sweeps using ‘Pick Lines’.
  6. After you have modeled the custom 3D geometry in the Generic Model family, create a Baluster Post family.
  7. Load the Generic Model family into the Baluster Post family.
  8. Load the Baluster Post family into the Project.
  9. Apply your new custom Baluster Post to the Start / Corner / End post of the Railing you are trying to correct.
  10. In the Baluster Post family, rotate and move the Generic Model family around until it is in the right place and reload into the Project.
