Hello everyone. I have a problem with creating a handrail in 3d for stairs,  if you take a look to my   drawing  attached to this post.I need to divide that red part of handrail in two equal parts and adjust by ucs that i could to print them out in 2D like this ( please see the picture in 2d view).uploads/204404/Plot.pdfI would appreciate any help.Thank you for your time.uploads/204404/Stairpro.dwg

Eldorado: I don't know if you realize it or not but your drawing is based on a template that uses IMPERIAL units.  In this case they happen to be DECIMAL inches.  Given that your location is listed as the United Kingdom wouldn't you rather be drawing using a template based on METRIC units?Your stringer actual measures 40 INCHES wide not 40 MILLIMETERS.  Same thing goes for your riser height which you show as 179.  It is in inches not millimeters.BTW...40mm = 1.57 inches which is pretty close to the what it would be in the U.S.  170mm = 7.05 inches.

Yes, I did,t know  about it but this is not an orginal file, I  have copied from original file which is in decimal. Thank you for note

OK...you know.  Are you going to do anything about it?Do you know how to extract the 2D views from the 3D model?

Yes I know but in this case is more complicated. I think about  how to set the coordinate system usc that I could extract  2D .If there would be a  two arcs instead helix ,would be no problem.

What command will you be using to extract the 2D views?  It may not make that much of a difference what your UCS is set to.

using SOLVIEW and SOLDRAW but have no idea for now how to set the USC in the  irregular space with that helix .

Set it for a plan view then derive the other views from it.

I have done but unfortunately is not accurate design. I have done with arcs as i said before and adjusted the ucs.There is  a file uploads/204404/StairproHan...dwg

Do you mean in the paper space?

[QUOTE=Eldorado]Do you mean in the paper space?[/QUOTE]To extract the 2D views first go into model space and set the view to TOP.  Then switch to your layout to create your 2D views using SolView and SolDraw.Another option would be to use FLATSHOT but you have to be in model space not a layout to use that command.

I have done everything.You should to see the drawing to understand what i mean. If you take a look  from the top view, the handrail  is not exactly in the center of string.Im looking for more accurate and faster way to do so. May be it should be done on the lisp routine.

I can't seem to download your drawing.  Never mind.  I got it.One problem I see right away is that you have a section of a helix, in red, partially overlapping another helix, in white.That's not good.There is no faster/more accurate way to do it.  Have you written lisp routines?  Would you use a spline to create the centerline of the handrail?

Yes i know about overlapping as i said is not a original drawing. Might be I'll try to write in autolisp, dont know yet. I used the arcs, splines and helix  for central line.

Well the problem with that is since the centerline is not a single, continuous entity then you will have to sweep or extrude your handrail profile, whatever it might be, along each and every segment and in the process make sure you have no overlapping that could cause problems afterwards.Good luck doing that.  I'll be interested in seeing the final result.

Thank you for replies and  good luck to you. I'll upload for you a picture of final design
