Display the Center Point of an Arc

In Pythagoras, you can quickly calculate the center point of an arc or circle without drawing it manually. This is useful when you need a reference point for further calculations or constructions.

STEPS

1. Select the arc in the drawing.

2. Go to the menu: Calculation > Center,
   or right-click the arc and choose Calculate Center.

3. Pythagoras will automatically place a point at the center of the arc.

This point is displayed with the 'X-cross' style in the drawing.
Other point attributes (like color or layer name) follow the current default settings.

Center Point of Arcs in a Polyline

Is your arc part of a polyline? Then you first need to split the polyline.

STEPS

1. Right-click the polyline.

2. Choose Edit > Unpack.

Your polyline will now be split into:

• Straight segments → become individual lines

• Arcs → become separate arc objects

• Curves → are simplified into points and lines

After splitting, you can calculate the center point of each arc segment as described above.
