For the size that isn't on the drawing. Pick the shape, type in what you do know and leave the rest blank; it works out everything else. Click any answer to copy it.
At least one must be a side. The right angle is between a and b.
Each angle is opposite the side with the same letter.
Chord + height gives the radius of a part you can measure across.
Drawing says "2 × 30°": length 1 = 2, angle = 30. A plain "C2" is 2 × 45°.
Enter the top Ø or the depth; the other is worked out.
Half the included angle is what you set on the top slide.
| Hole | Angle ° | X | Y |

Measured from the centre the drawing dimensions from.
Enter the angle or the stack height.
Type in either box; the other follows.
Angles in degrees, lengths in mm. Results are rounded to 3 decimal places for lengths and 4 for angles; check critical sizes against the drawing before cutting.
