The relative calculator is located in the Prepare workspace inside the support tool.
It’s a pro feature meant to edit a support selection by individually increasing or decreasing a selected parameter.
Combined with features like the selection (Supports > Selection > Select close to Medium Support, for example ), you can increase all the selected support tip diameters by 20% individually because you scaled up a model to reinforce the supports.
Once you have selected your supports, go to the Tip, Mid, Base, or Base Tip tab to edit a parameter by clicking on the +/- icon on the right.
Step1: Select if you want to decrease – increase +, or change the value based on a percentage %
Step 2: Type the value directly.
Step 3: Use the preset button to change the value quickly instead of typing it.
Step 4: Apply the modification.
The undo won’t change the values back, it will cancel the last action done before you apply the new value change. If you need to undo it, you must use the Relative Calculator again.
