Line

1. Click to begin and end line segments, continuing to create attached segments.
2. Or, click and drag to start one segment and release to end.
3. Optionally, immediately after the line is created, input a numerical value (or type "=#" to input a variable) for the line length and press enter. This dimensions the line without having to use the dimension tool.

To input a variable in any dimension field after the geometry is already sketched, the equal sign (=) is not required. Type "#" to input a variable.

1. Click and click the first point of the line.

2. Click the second point of the line to create the first line segment.

3. To start a tangent arc at the end of the line segment, either:

   • Click Shift+a to switch from the Line to the Tangent arc sketch tool.

   • Move the cursor near the end point until you see the line icon switch to a tangent arc icon (highlighted in red in the image below).

4. Click another location to set the end point of the tangent arc.

5. After the tangent arc is created, the sketch tool automatically switches back to Line. You can continue to create a new line segment starting from the end of the tangent arc, or press Shift+a again to start creating a new tangent arc from the end of the previous one.
