# How to keep the “center mark” at the center of the circle or arc?

How to keep the “center mark” at the center of the circle or arc?

I wanted to keep the “center mark” at the center of the circle but sounds not to work!

Is there a way? Or do we need to draw it using the “point” command?

Thank you for the help

Hi,

>> I wanted to keep the “center mark” at the center of the circle but sounds not to work!

Not for object-snap, if you have more osnaps active than "center".

If you need it very often I would create a block with a circle (radius = 1) and a point in the center, then create a block from these two objects and for every position you want to have a circle you can now insert this block with a scaling = radius.

It's a workaround, because it does not give you the mass of construction-options like TAN-TAN-RADIUS or PNT-PNT-PNT or ..., it also can't be trimmed without beeing exploded.

You can also use your idea with point (without building a block), but then your point should be "connected" via constraints to your circle-center.

Draw a point in the center of the circle, use geometric constraint to constrain the point to the center of the circle. After you do this, move the point, the circle moves. Move the circle, the point moves.

If it needs to show up, draw it just like you wrote.
