I draw a helix and use the command along the spine line. The spine line is shown in Figure 1. The spine line is parallel to the Z-axis. The operating parameters are shown in Figure 2. The resulting of the helix is shown in Figure 3. Take the 1, 2, and 3 points on the helix line, as shown in Figure 4, measure the distance from these points to the spine line. The measurement method is shown in Figure 5. The results obtained are shown in Figure 6. The results show that the three points are to the spine line. The distance is different, the origin file locates in attachments, I hope to get the same radius of the helix, I don't know why, who can tell me?
Solved! Go to Solution.
In your first case, the spine curve is shorter than your helix length; the distance from the helix end point to the spine picks up some distance in the Z direction (as alluded to by @AmolKadam ). For the first case, try lengthening your spine curve or measuring to the Z datum axis instead of the spine curve.
