Drawings · Lesson 3: Dimensions and annotations

Dimensions, geometric tolerances, notes, blocks and notes linked to dimensions and properties.

Lesson goal

1. Watch the videos

Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.

Detailing: DimensionsVideo 1▶Detailing: DimensionsImport model dimensions, create driven dimensions and move them between views.↗ Annotations and Drawing BlocksVideo 2▶Annotations and Drawing BlocksNotes, geometric tolerances, symbols and reusable blocks.↗ Parametric NotesVideo 3▶Parametric NotesLink a note to a dimension or a property: the text follows the model.↗

2. Key takeaways

1

A model dimension drives the part, a driven dimension (added on the drawing) only measures it.

2

Geometric tolerances attach to a face or a dimension; datums (A, B, C) are placed with the datum feature symbol.

3

A block saves a set of annotations (logo, in-house symbol) that you can reuse on all your drawings.

4

A parametric note displays a dimension or a property: it updates by itself.

Tip

Save the notes you type often (general tolerances, surface finish) in the Design Library: a drag and drop is then enough.

3. Do the exercise

On your part drawing:

  • add a position tolerance on a hole, referenced to two datums
  • create a note that displays the part material from its properties
  • save your logo as a block
✓To check: Change the part material: the note must display the new material.
