Revit System Families

System families contains family types that are used to create basic building elements such as walls, floors, roofs and ceilings in your building models.

System Families

System families are predefined in Revit and saved in templates and projects, we cannot create, copy, modify or delete the system families, but we can duplicate and modify the types within system families to create your own custom system family types, we can also copy and paste or transfer system family types between projects and templates.

To change the family type, we can select an existing type from the pull down in the properties or you can create a new family type.


Link CAD files in Revit

AutoCad Files should not be imported into Revit Project, they should always be Linked to have a control on the files.


  • In Revit window go to Insert and Link Cad option for inserting cad into Revit
  • Import cad option should not be used for inserting cad as importing creates issues while deleting or changing
  • Linking CAD enables full control of the AutoCAD data in Revit project

When linking following steps shown in the image should be looked into.2

CAD links can be reloaded, unloaded or removed from Insert > links>Manage links>CAD Links

Draw Order of Detail Components

Draw order options are available when you select detail components in the view.

In the drawing area, select one or more detail components.

The following tools become available on the Modify <element> tabArrange panel.

  •  (Bring to Front). Immediately places the selected detail components in front of all other detail components in the view.
  •  (Send to Back). Immediately places the selected detail components behind all other detail components in the view.
  •  (Bring Forward). Moves the selected detail components one step closer to the front of all other detail components.
  •  (Send Backward). Moves the selected detail components one step closer to the back of all other detail components.

Revit Dimensions

A small tip which you might have forgotten or you are not using….

We can delete any dimension from a full dimension string. 🙂

Revit Dimension -Tip

We can just press Tab button and select one dimension from this full string and delete.

Revit Dimension -Tip-1

Hoping that this information will be useful to Revit beginners and also for those who are not using this.


Revit Workflow for Beginners

The time when you start a practice project. Try taking a small project so that the understanding of the workflow and elements becomes more clear.

5 easy steps to follow.

  • Start a new project
  • Build the model :- try gathering the maximum information required to build the model
  • Information of other disciplines :- try adding entities of other disciplines, if the project is architecture design then add few structural and MEP elements, just a basic families.
  • Document the model:- Add Annotations (tagging and dimension every element)
  • Present a model :- Prepare a small presentation,use sheet setup, 3d sections etc.

These steps are only for the early learners of revit, when they want to start a practice project to check their capabilities.



BASE AND TOP LEVELS: Stairs are based on selected levels that already exist in the project. You can add an offset on these levels if required.

DESIRED STAIR HEIGHT: Total distance between the base and the top of the stairs, including offsets.

DESIRED NUMBER OF RISERS: Automatically calculated by Revit, dividing Stair Height by Maximum Riser Height.

ACTUAL NUMBER OF RISERS: The number of risers you modeled so far.

MAXIMUM RISER HEIGHT: Riser height for your stair will never go above this value.

ACTUAL RISER HEIGHT: This distance is automatically calculated by Revit, dividing the Stair Height by the Desired Number of Risers.

MINIMUM TREAD DEPTH:  specify the minimum tread depth & we can go above this number, but not below.

ACTUAL TREAD DEPTH: By default, this value is equal to minimum tread depth set in the stair type.

MINIMUM RUN WIDTH: Set on the stair type, you can specify the minimum run width.

ACTUAL RUN WIDTH: By default, this will be the same as the minimum run width.

Revit -Object Styles/ Line weights

Set the object styles and lineweights in the project template so the output graphics meet your requirements.

Start by setting the object style lineweights. These are set relative to one another to represent how you want elements to display graphically next to each other.

To help with setting object styles in the template:

  1. Create a sample plan detail using elements from different categories which use different object styles.
  2. Duplicate this view and change the scale so each view shows the same elements but will be printed/shown at different scales.
  3. Compare the on-screen and printed appearance and adjust the object style settings, as required.
  4. After the object styles are defined, make adjustments to the object style lineweights for each scale to ensure the required output.

These steps may need to be done multiple times as you refine the object styles and line weights for each view scale.
