Modify the design
The final step is to modify the design by changing parametric values.
1. Click > > > .
2. Click R4 (green dimension) and enter 3. Creo Elements/Direct Drafting changes the radii of all six circles — the yellow (annotation) dimensions are also updated.
3. Click Delete and delete the six yellow dimensions.
4. In Generate Constraints, click the Show radio button, select Size from the Type list, and click Apply.
The parametrics module has used the actions performed during the creation of the design to generate constraints for dynamic modification of the design.
5. In Generate Constraints, click the Assign radio button, select Size from the Type list, and click Apply.
6. Click the original circle at G.
7. Enter 'Borehole_radius'on the command line.
8. Click End.
9. Click Advanced in Current Constraints.
10. Click the value 3 in the column New Value or Expression.
11. Enter 4 and click Preview in Solve.
12. Click Keep in Solve and click the design.
13. Move the copy of the design to another location (you may need to Pan).
14. Click the destination point for the copy.
15. Click End.
16. Click Fit.
Note the smooth transition from simple design creation using the green driving dimensions to parametric design.
