hello, In the attached STP file i am trying to change the profile of the handrail on the curved sections to the profile in the attached DXF file. I used the command Dupedge to convert the bottom left and right edges of the existing pieces into lines. Then i aligned the new handrail profile on the end of the rails and used the sweep 2 command to make a new curved piece. the solution had the bottom of the new piece follow the old one just fine but the top is way skewed. for the project that we are doing it is critical to keep the pieces as close to the original sweep as possible. does anybody have any ideas or experience with this issue? 6710 Handrail.dxf (142.4 KB)
your curves are pretty tortured… They are like 500x more complex than they need to be and the actual shape of the curve is kinda all over the place, which results in a very wavy curve…
I can’t imagine that is what you want for an elegant handrail.
That said, using what you have provided, I’d dupe edge then run rebuild at degree 3 with 7 or 8 control points to get a much simpler/ cleaner curve. (Personally, I’d spend a lot more time sweating the shape of the curve to remove all the lumps and bumps…)
then run sweep 2 with a slash in the middle to constrain the isoparm flow.
A better way to do this is to establish you straight sections first, then use blend curves to determine your curved sections. Once you have 1 rail curve created, sweep 1 a straight line section to create a surface that would be the bottom of the handrail.
dup that edge (delete the surface now) and rebuild the curve as necessary to get the point count down to a reasonable level.
then sweep2 your profile using slash as a way to adjust the isoparm flow to be more or less perpendicular to the rails. Don’t over do it though… a few slashes is plenty. do all this with history and you can adjust as needed to fix any issues that arise.
