Sketching a Tangent Line in Sheet Metal

  1. Select the Sheet Metal tab.
  2. Click Tangent Line in the Sketch group.
    Curves are highlighted as you hover over them, and the tangency indicator appears at your cursor location. If there are no curves in your design, this tool is disabled. You must add a curve to create a tangent line.
  3. (Optional) Click the Profile option if you want to create walls as you sketch.
  4. Click the curve you want to draw tangent to.
    As you move the mouse, the start point moves so that the line remains tangent to the curve.
  5. (Optional) Dimension the line with a length.
    You cannot dimension from another sketch object when creating a tangent line.
  6. Click to set the end point of the line.
    If you move your mouse over another curve, the line snaps so that it is tangent to the second curve. Hold Alt to stop your cursor from snapping to curves.
