How do you give a datum?

Notation is Important on Drawings

  1. Point with a solid or dashed leader line with the datum feature symbol placed on it. …
  2. Datum feature symbol placed directly on a planar surface.
  3. Symbol placed on an extension line off the datum feature surface.
  4. Leader arrow with the datum feature symbol pointing to a planar surface.

How is a datum established?

Datums are established using datum features and simulated datum features. Multiple datums can also be combined to make a datum system that specifies a feature. A real (non-ideal) integral feature of a target used for establishing a datum (e.g. surface of a part or hole).

What are datum used for Solidworks?

You can attach a datum feature symbol to the following items: In a part or assembly, on a planar model surface or on a reference plane. In a drawing view, on a surface that appears as an edge (including silhouette edges) or on a section view surface to identify datum planes in the part. A geometric tolerance symbol …

Create a Datum Feature Symbol



In the Annotations group on the Annotate tab, click Datum Feature Symbol. A datum feature symbol will appear next to your cursor, and will move with your cursor. Drag the datum feature symbol to place it on a surface or another annotation.

What is a simulated datum?

Simulated datum: A point, axis, line, or plane consistent with or resulting from processing or inspection equipment, such as a surface plate, inspection table, gage surface, or a mandrel.

What is datum modifier?

When an (M) modifier is used in the geometric control frame along with a datum letter, the datum axis or the datum center-plane is established by the axis or the center-plane of true gage surface at the WCB of the feature-of-size.

What is a datum point?

In engineering and drafting, a datum is a reference point, surface, or axis on an object against which measurements are made. These are then referred to by one or more ‘datum references’ which indicate measurements that should be made with respect to the corresponding datum feature .

What are 3 types of datum?

Major Types of Datum Features

  • Datum Plane.
  • Datum Line.
  • Point.

Why is it necessary to create a datum when marking out?

When marking out an object, datum references are used as a reference point for all measurements to be taken from and can be chosen by the manufacturer. By taking measurements from a small number of set points, accuracy can be improved and maintained.

How do I add GD&T to Solidworks?

To set geometric tolerance properties, do one of the following:

  1. For parts, click Geometric Tolerance (DimXpert toolbar) or Tools > DimXpert > Geometric Tolerance.
  2. For drawings, click Geometric Tolerance. (Annotation toolbar) or Insert > Annotations > Geometric Tolerance.

  2. After you create the datum feature symbol, drag it onto the dimension or geometric tolerance symbol.

How do I create an ordinate dimension in Solidworks?

To create ordinate dimensions:
