When inserting a view from a part/ assembly into a drawing, you may have noticed there are some incorrect dimension values on your drawing views.
More often than not the issue is related to a setting in the drawing view’s property manager.
Under the section “Dimension Type”, there are 2 types of dimensions:
1) True accurate model values
2) Projected 2D dimension
In general, Projected Dimension Type is used on orthogonal view (front/ top/ right),
True Dimension Type on isometric view.
The example above shows the dimension in both types with the value obtained.
True Dimensions are “accurate model values”.
If you were to measure the length of an edge, distance between edges/faces within a part/ assembly,
this measurement will be the same as the one from True Dimension Type.
Projected dimensions are 2D dimensions.
Imagine you were to measure the length of the edge as it appears on the drawing.
From the model, the dimension values are as shown below.
SOLIDWORKS by default, specifies:
– “Projected” dimension type for standard & custom orthogonal views
– “True” dimension type for isometric, dimetric and trimetric views
