What is geometry in Revit?

Use 2D linework to add detail to solid geometry in certain views or to create a symbolic plan representation of an element. … As you create the family geometry, you can specify the visibility, material, and an optional subcategory of the geometry.

How do you create geometry in Revit?

Create solid geometry with the Create Form tool.

  1. On the Create tab Draw panel, select one of the drawing tools.
  2. Click in the drawing area, and draw a closed loop.
  3. Select the closed loop.

What are the 5 ways to create geometries in a Revit family?

5 Create and pin geometry

The tools that Revit offers to generate geometry are: Extrusion, Blend, Revolve, Sweep. Swept Blend and equivalent Void forms. When working in an elevation view or a section and starting to draw a geometry, Revit will ask which is the reference plane that we want to use.

What are the three types of elements in Revit?

Revit Architecture projects use 3 types of elements:

  • Model elements represent the actual 3D geometry of a building. For example, walls, floors, and roofs are model elements.
  • Annotation elements help to document the model. …
  • Datum elements are non-physical items that are used to establish project context.

How many Revit categories are there?

There are three classes of families within Revit: system families, loadable families, and in-place families. System families form the basic building elements, such as walls, floors, roofs, ceilings, and other elements that you would assemble on a construction site.

What is Revit family creation?

BIM objects are a family of intelligent virtual 3D objects that provide detailed information of a product or component about its physical characteristics such as its geometry and visual graphical representation.

What is family type in Revit?

The 3 kinds of families in Revit are: system families, loadable families, and in-place families. … Loadable families can be combined to create nested and shared families. Non-standard or custom elements are created using in-place families.

What is parametric families in Revit?

If you want a family that can change size or has moving parts, create a parametric family –that is, one that uses parameters to control its behavior. In this case, you need to build a framework using reference planes and reference lines.

What are the 2 types of components in Revit?

There are 2 types of view-specific elements: Annotation elements are 2D components that document the model and maintain scale on paper.

Elements for Revit

  • Windows, doors, and cabinets.
  • Beams, braces, and structural columns.
  • Sinks, boilers, ducts, sprinklers, and electrical panels.

What is datum in Revit?

Datums are Revit elements that fit the project. They are used as references while modelling such as levels, grids or reference planes. They are finite representations of infinite planes (vertical-grids, horizontal-levels, sloped-ref planes) that are shown as lines.

How do you join walls in Revit?

You can join the geometry of closely-spaced parallel walls.

  1. In a plan view, place the walls less than 6 inches apart.
  2. Click Modify tab Geometry panel Join drop-down Join Geometry.
  3. Select the walls to join. If either wall has an insert (such as a window), it cuts through the joined wall.

How do I join an adjacent wall in Revit?
