Transparent calculator is the one which helps to access the expressions of an existing geometry using the object snap functions without leaving your active command.

Command :

**‘CAL**
Snap mode:

**END**- End point**INS**- Insert**INT**- Intersection**MID**- Midpoint**CEN**- Center**NEA**- Nearest**NOD**- Node**QUA**- Quadrant**PER**- Perpendicular**TAN**- Tangent

Shortcut Functions:

**DEE**- Distance between two endpoints.**RAD**- Determines the radius of a selected object.**ANG**(end,end,end) - Angle between two lines.**ILLE**- Intersection of two lines defined by four.**MEE**- Midpoint between two endpoints.**NEE**- Unit vector in the XY plane and normal to two endpoints.**PLDEE**- Point at a distance along a line determined by two endpoints.**PLTEE**- Point at a parametric location on a line determined by two endpoints.**VEE**- Vector from two endpoints.**VEE1**- Unit vector from two endpoints.

Examples:

- Draw a circle with a half radius of an existing arc

- Offset a line with distance of existing parallel lines

- Fillet lines with the radius of existing arc

- Calculating with expressions
