I saw this thread about making a design plane to a point along an arc. How would you go about making sure each plane is a specific distance from another one? So when you add an object to each plane they match the plane angle and are the specific distance? As you can see, I am trying to make eyelashes around the eye along a curve.
Did you mean to ask me or SHAPR?
- Create rectangles
- Lock in their dimensions and make them horizontal/vertical
- Lock the distance between two of their points
- Snap their mid-point to the arc

I interpret your requirement slightly differently and again this is only another way of achieving an objective.
Assuming that you have a Circular Curve [Circle or Segment of a Circle] and you wish to divide it equally and add Planes at a specific Angle.
This is one way of achieving the objective.
In this case it is dividing one quarter of a Circle into 8 equal parts, 90º ÷ 8 = 11.25º. Sketch a Radius Line and use Transform > Move/Rotate > Hit the ✚ Icon to pivot the Line from the Centre of the Circle typing in the Angle.
Repeat as necessary:
Use Add > Construction Plane [CP] > Choose Perpendicular from Point place a CP on the end of each Radial Line:
Use Transform > Move/Rotate To adjust the angle of the Plane(s) to the desired degree, these have been set to 40º:
Assuming the need is to divide a Curve/Arc equally, S3D provides sufficient information for the maths to be done:
If the task involved something more complex I would divide a combo Curve using a series of Circles on a trial and error basis, but this would only provide an approximation:
In the image I posted, I want the spacing between the centers to be the same. I want the center vertical line of the each rectangle to be perpendicular to the arc.
Choose the Arc and move the Point as required
