Modeling an octogonal pole
Modeling an octogonal pole
(OP)
Dear All,
I am trying to model an octagonal pole for electric distribution. I have made by different ways but I want to know if it is possible make an extrusion with taper.
What I want to do is draw the base octagon (inner and outside) and the same in other plane with the top of the pole. And made an extrusion to create a pole. I have tried but I can’t do it. Is it possible?
When I model the pole by other ways I find a problem to fix restrictions. I can’t select the bottom area of the pole.
And other problem is when I made a small window in two opposite sides of the pole in order to help to evacuate water. It is demanded by one of our clients.
Thank you for your help.

If so, the command is called "Thru Curves". An Extrusion in NX will not accept multiple profiles in different planes and in the same operation. (or at least not go between these.)

"octopole2_2" follows your desire to "draw the base octagon (inner and outside) and the same in other plane with the top of the pole". It uses two tapered extrusions controlled by reference lines drawn between the top and bottom sketches.

Here is something simple that I came up that I think is similar to what you need.
RE: Modeling an octogonal pole
thank you very much for your help. All your comments have been very useful.
MustafaAsan It is just what I want. I have done one just like these but I have problems when I mesh. I can’t select the right surface to fix the restrictions.
Toost It is exactly what I try to do. I will try with your indications.
Mmauklin, your second file is just what I was trying to do. When I create a mesh and put the restrictions It works well. I will try to create the window I need to evacuate water and I will see how it works.
Jerry1423, your file is what I was looking for. I will try to create the window I need to evacuate water and I will see how it works.
I will work wiht all of this and try to make my analysis.
Thanks.

I have made my model with and extrusion and later making a shell. In my model when I messh I can't select the top and the bottom surface. Why? And I need to apply the wind pressure, how I have to apply? With hidrostatic pressure and changing the values? Sorry but is my first month with this software.
RE: Modeling an octogonal pole
There are many different ways to model depending on your "design intent".
As for analysis - it's all beyond me (apologies), although your mesh looks sharp rather than flat at the bottom. Smaller triangles?? (total guess)

So I tested it and errrrr, very odd! Never seen shell do that before.

You might think that the outside of your octogon has 8 faces, but it does not. The swept feature is approximating your input with splines and the shell feature is exaggerating what happened with the approximation. In your picture, you can see a black "edge" line at the top right side, but there is no "edge" line at the next corner (moving clockwise around the octogon).
Try turning on "preserve shape" option in the swept feature and check the results.

I have mesh wiht CTETRA(4) tool, do you think is right? With this way my octopole is perfect to fix de areas I want. When I use CTETRA(10) I have problems as I have shown before. My mesh looks sharp! Could anyone explaim me de difference between use CTETRA(4) or CTETRA(10)?
