Hey all, there might be an obvious answer from those out there with more experience with AC's so can anyone help with maintaining an alignment between an AC Placement point and an AC reference point. I'm attempting to create a sweep on a 4 point spline using a top and bottom rail where the z height of the sweep profiles are controlled at the placement points. The image below shows placement point 2 with a set of reference points and lines that need to maintain their position on top of the placement points. Any ideas to to set this up? The Align command works to align the 2x vertical reference lines but there is no option to lock this alignment.

Hi
Try this..
If you want to keep four or five adaptive points aligned ..
then " align" a plane to one common plane of first point..
and lock it..
so that moving any one point will move others as well..
Best luck

You'd have to "host" the reference point on the placement point.
Then your question was misleading, but you can still use the same method only instaed of "hosting" to the placement point, you have to host to a point placed on the spline.
Thanks but I'm not wanting to keep alignment between multiple adaptive points, I'm wanting to keep alignment between an adaptive point (placement) and a spline-hosted reference point. The hosted point is used to drive the z value of a swept profile and the adaptive point (placement) gives the x & y placement values. The issue is that the xy of the reference point is not the same as the adaptive point so I cant define the geometry precisely.
Again, I'm not sure this works. The hosted reference point's location along the spline requires either a dimension or a percentage value, neither of which (with my nube's knowledge) can be related to the position of the placement points position on the same spline. If you can explain how to relate these 2 positions then this would probably solve the problem. Cheers again.
Now I 'm confused as to what you want to achieve.
Maybe this explains things a little better. Placement points 1, 2 and 3 drive the x,y points of the spline. The z location of the upper spline is driven by a dimension parameter. 3 sets of profiles are used to generate the geometry and each set can have a different z value. All profiles are normal to the splines. The profiles at the start and end of the splines are located using Normalized Curve Parameter = 0 & 1 respectively. The profiles nearest point 2 need to be AT point 2. I cannot find a way to lock an alignment between any of the given geometry, nor define dimensions or formula so that this alignment is always maintained. This seems like a simple problem but is proving beyond my limited knowledge of such things.
Make reference line (green line in picture).
Select point A
Click [ Host Point By Intersection ]
Pick the newly made Reference Line.
repeat for point B
