I am trying to copy a rectangular component (2x3) around an arch so that each component is tangent to the arch. I have used the plugin Path Array to create the attached illustration. As the 2x3s follow the arch, the plugin arrays the components along the red axes. Is their a way to copy the components so that they will be tangent to the arch at their intersection? Any help will be appreciated. ![image](https://global.discourse-cdn.com/sketchup/original/3X/d/7/d7311b44abc5fe5710a1c1957dfc2e687335873c.png) ![image](https://global.discourse-cdn.com/sketchup/original/3X/f/5/f5ff29904c62b80edee0961a91b99104f50a7826.png) ---

Another option would be to use Copy Along Curve from Sketchucation. ![copy](https://global.discourse-cdn.com/sketchup/original/3X/b/6/b6c8bc7fdef54071c12cb7806cc972dc155fc2e3.gif) ---

I rotated each component individually from the earlier example and this is what I was trying to do with a plugin. I used the SketchPlus extension. ![image](https://global.discourse-cdn.com/sketchup/original/3X/5/e/5ee03150e44f70e683937e5a54e9dfc55ebb7555.jpeg) ---

You’re welcome. BTW the last purlin at the bottom on the right wasn’t made because my curve wasn’t quite long enough for the spacing I selected. Easy enough to make one additional copy with Move/Copy to fill in.
