I’m not sure how to phrase it exactly, but what I want to do is have a blended curve match another curve exactly as if projected. The images show the blended curve in the making and a layout curve below it on the construction plane that I want to match. Is this possible? How?
Not sure , but have you tried command “Crv2View”
First of all you should check if the profile is curvature-continuous with those curves too. It could be only tangent. An inexact method would be to use Adjustable Curve Blend, and pull the tangency handles, so the new curve visually matches the profile. An additional step would be to extrude the profile in Z direction, and use Pullback with the blended curve to stick it to extrusion.
Try extruding the curve you want to match in the projection to create a surface the blend curve should be on.
Create an initial blend curve using Blend or BlendCrv.
Pull the initial blend curve onto the extrusion.
In theory if the extrusion has the same level of continuity with the curves to be blended as the initial blend curve, then the pulled curve should have the same level of continuity. However my experimentation shows the results of Pull can be noisy.
Edit: Try using RemoveMultiKnot to fix any curvature continuity with the pulled curve before using the procedure below.
To clean up the noise try rebuilding the pulled curve, use Match to match the rebuilt curve to the end curves, then Pull the revised curve so that it lies on the surface. Several iterations may be needed.
Thanks folks. I did extrude the pattern curve and projected onto it the curve created from the blend. It didn’t seem to be exactly what I’d hoped. By pulling the curve you both mean manually I take it and getting as close as possible. Is there actually a method to ‘stick it’ to the surface? [quote=“0netech, post:3, topic:28142”]
use Pullback
