Revit Drafting and Fidelity

Revit supplies a range of droughting tools to assit the development of models and drawatings.

Like other systems, the system use Reference plane (analogous to the “contraction line” line used in many CAD systems) and tools such as “alignment”.
The general workflow is to drop the entity onto the drafting plane and them move it into place.

  • With CAD, one usually draws from a x,y,z point and shaping the forms a as you develop the design.
    • The line are “sculptured” into place.
  • With Revit, I sketch the entities onto the drawing plane and then corral them into place, often locking the entities to reference planes to form the design.
    • This allows adjustment of the design by flexing of the entities to adjust shaping using the alignment tools, plane locking and dimension locks linked to parameters.

0.7 mm line limits

Revit does not support entities that are less than 0.7mm. An aluminum windows profile cannot be drawn with any finer precision and import one from a CAD system often drops around around 30% of the entities.

Pen weight

Very complex

Annotation Alignment

Difficult to align text to entities, Align between text well.

Crop boxes

Very use for controlling the extents of sections and planes but very difficult to place with any precision. Has positioned by eye.
