Issue:
You would like to have Geometric Constraints automated. When you draw an object in AutoCAD geometric constraints would be added automatically.
Example: if a line is drawn Horizontal or close to it then a Horizontal Constraint is automatically added.
Causes:
This can be done using the CONSTRAINTINFER (System Variable). This System Variable is turned off by default.
Solution:
Autodesk Help description is as follows
CONSTRAINTINFER (System Variable)
Controls whether the geometric constraints are inferred while drawing and editing geometry
0 |
1 - Geometric constraints are inferred
Type: |
Bitcode |
Saved in: |
Registry |
Initial value: |
0 |
To enable this System Variable
- Once in a Drawing in AutoCAD.
- Type CONSTRAINTINFER in the Command Line and select the <Enter> Key on your Keyboard.
- Type 1 (to enable the System Variable) and select the <Enter> Key on your Keyboard.
- CONSTRAINTINFER is now enabled. Objects edited or draw will now Auto-Constrain.
To disable this System Variable
- Once in a Drawing in AutoCAD.
- Type CONSTRAINTINFER in the Command Line and select the <Enter> Key on your Keyboard.
- Type 0 (to disable the System Variable) and select the <Enter> Key on your Keyboard.
CONSTRAINTINFER is now disabled. Objects edited or draw will not Auto-Constrain.
