### Tip : Transparent calculator an Introduction

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
• PER - Perpendicular
• TAN - Tangent

Shortcut Functions:
• DEE - Distance between two endpoints.
• 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
