AutoCAD Drafting in Revit- 2D Drafting Tools

As Revit is a modelling program that enables you to model (draw) an entire project in 3D 
you need to display this model in a manner that can be viewed by others for construction.
To ensure these views are in a manner that matches your current office drafting standards and to 'tell the story' you will need to do 2D drafting at some stage. Revit keeps it simple and generally has enough for what you need.

Some of the items include:

• Detail lines
Use the Detail Line tool to draw detail lines to provide additional information to the model geometry in detail views and drafting views.

• Filled regions 

Create a view-specific graphic that fills an area with a pattern. You can use filled regions when detailing a view or creating an annotation family

• Detail components 

Detail components are line-based 2D elements that you can add to detail views or drafting views. They are visible only in those views. They scale with the model, rather than the sheet.
Detail components are not associated with the model elements that are part of the building model. Instead, they provide construction details or other information in a specific view.

• Detail groups 
A detail group is a collection of view-specific elements that you can then reuse within other views.

• Masking regions 

Masking regions are view-specific graphics that can be used to obscure elements in a view.
Masking regions may be useful in scenarios like the following:
  1. You need to obscure elements in a project.
  2. You are creating a detailed family or a model family and need the background of the element to mask the model and other detail components when it is loaded into a project.
  3. You need to create a model family (from imported 2D DWG files) that obscures other elements when placed in a view.
• Repetitive details.

2D drafting should only be used when there are limitations to the 3D model. Apply when you just need a quick detail or need additional information with your model element.


Note :

2D drafting elements are often called “dumb intelligence”, i.e. if a steel member moves from its original position the 2D detail element WILL NOT move. Try to lock the 2D drafting elements to the 3D model components wherever possible. This way they will move with modelled elements.

Revit in AutoCAD Language

When migrating from an AutoCAD background to Revit, one of the hardest tasks for
converts are understanding a similar language between the two packages.

When it comes to similarities, there are three main topics to discuss; 2D, 3D and Rendering. Both AutoCAD and Revit are used to create 2D drawings such as floor plans, elevations, details, etc. There may be slight differences on how they're presented graphically but essentially the end result is the same. With both you can generate a set of construction documents.
