Was wondering if anyone knows a way I can align a new polyline to a reference polyline (orig polyline).
The 2 polys will be generally the same length, however, the number of vertices will differ.
Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.
Looking for any help thats out there.
No the align command is for a simple straight line adjustment. This isn't what I'm doing.
I'm looking for a way for the the new polyline to 'lie' directly ontop of the reference poly, without the overall length of the new poly changing and the distances between distances between th vertices staying the same.
read the command line and answer in the negative to scale objects
Once again, it is not a simple straight line adjustment, so the align command doesn't suit.
The 2 polys are generally the same length, with different numbers of vertices and different distances between vertices.
I need the new polyline to align - as close as possible - to the reference poly in all directions and at all vertices, not simply the start and end points.
The parameters, criteria, and how you would go about implementing a solution seem pretty confusing. Depending on the polylines you are wanting to align to each other the parameters change, so how do you define a standard way of handling it, even if the polylines are somewhat similar.
So I think that maybe you have to take a stepped approach. Just speculating here! Maybe you could use the "Create Line By Best Fit" to fit a line through each polyline possibly using the regression analysis to adjust the fit, then use the "Align" command to align one polyline-fitted line set to the other by using the fitted lines, and then move or adjust one of the polylines along the Align fitted line so that the beginning or ending match up the way you want to. Does that make any sense?
If not perhaps a drawing would help?
How bout a picture?
When you say align, the inference is that you want to correlate two or more points in space to two or more point in a different space that share congruency. If the poly lines are not congruent then how can you expect them to align?
What are you asking to do? Post a picture
I have this exact situation, and would like to know if there is a way to accomplish this task. Here is a pic.
The polyline that is gripped needs to be aligned with the red line. I typically grab the grip and move it perpendicular to the red line.
Note* I am aware of the straighted command under pedit, but that removes verticies.
If I understand correctly, the only way I know is manually:
Lets take the left side first: Hot grip your linefrom the vertice on the red line away from the arc, when you get to the end hold the last grip with the ctrl key; now pull the last grip toward the red line. If the line is equal to or less than the red line snap to it. If your line is longer than the red line: use the extension snap or draw a construction line before you begin.
Why is it not easier to redraw this geometry?
