Traverse all dimensions of component or model using SOLIDWORKS API

Dimensions in the sketch of weldment feature

This VBA macro demonstrates how to traverse all dimensions of the features from active SOLIDWORKS document or component (if selected) in the assembly using SOLIDWORKS API.

Macro will output the name of the dimension and the value in the current system units into the Immediate Window of VBA.

D1@Sketch1=0.15
D2@Sketch1=2.0
RI@Sketch11=0.008

The macro will exclude all duplicate dimensions as in some cases (e.g. weldment features) the same dimension may be present in the sketch and in the structural member feature as the same time
