Alpha / Compass design


People use compass in order to draw circle, but user can’t draw circle on big size. Because there is a limit size to draw a circle. So we need compass in order to draw any size of circle.

User can find a button in the hole of center part. If user presses this button,
Tapeline will be fixed.

We found a keyword from a tape measure. It can stretch as long as user wants to, and user can check detail length from ruler part easily.
If you hope to draw big size of circle, just pull a tapeline as you want.
Now user doesn't need a ruler and can draw any size of circle.
