Add an Equal Radius Constraint
General
- The equal radius constraint can be added to circles and arcs.
- The constraint can be set to selected circles/arcs in pairs, or the constraint can be set in such a way that the radius of the circle/arc selected first is set to all circles/arcs selected after that.
- The constraint can also be added to several selected circles/arcs at once.
- In sketch geometry, the symbol for the radius constraint is R .
- You can use the F9 key to show and hide the symbols of the constraints.
Add an equal radius constraint in plane sketch
- Select the function 3D Sketch | Constraints | Add equal radius constraint.
- Select the first circle or arc.
- The radius of this circle or arc is preserved, unless a radius or diameter constraint is defined for the arc/circle being clicked next.
- If you hold the cursor in place for a while after clicking the arc/circle, the program opens a mini toolbar with a button in the upper right corner of the cursor.
- If you want to select several circles/arcs at once, which will have the same radius as the first selected circle/arc, then select the mini toolbar function .
- Select the second circle or arc.
- The radius/diameter of this arc or circle will change unless it already has a radius/diameter constraint.
- If you selected the mini toolbar function in step 3, click more circles/arcs to which you want to set the same radius.
- Add new equal radius constraint by repeating steps 2 and 4.
- If necessary, stop continuously defining the equal radius by selecting the function again and after the first circle is clicked, select the mini toolbar function
- Stop adding the equal radius constraints
- Select another function or
- press the V key or
- press the Esc key or
- click the middle mouse button.
The effect of the mini toolbar
- The function is not selected : Only two consecutively clicked circles/arcs have the same radius.
- The function is selected : A circle/arc is clicked first and all subsequent circles/arcs get the same radius as the first clicked circle/arc.
Add a constraint to multiple circles or arcs at the same time
- Select the circles and arcs that you want to give the equal radius to.
- Hold down the Ctrl key while clicking the elements.
- Select the following contextual function: Constraints > Equal Radius.
- Circles/arcs receive the radius of the first clicked circle/arc, unless the selected circle/arc already has a constraint that defines the radius.
You can also dimension several circles or arcs at the same time:
- Select several circles or arcs.
- Select the context-sensitive function Constraints > Radius.
- A radius constraint is added to the circle or arc that was selected first and an equal radius constraint is added to the rest of the circles or arcs.
