Helical Guardrail

3D Design Volume Model
1

Hello,
This question has probably already been asked and I apologize in advance for bringing up the subject in this case.


I am currently working on a railing for a semi-spiral staircase and want to model it but I am stuck on the design of the rungs that rise in a helix on the upper half of the staircase.

 

I've already done a little digging on the different functions but with my student version I get lost quickly ...


Thank you for your answers.

Hello

 

See this question (that you asked):

Hello

 

Why not go through a 3D sketch that follows the curve of your staircase, and put a mechanically welded tube on it.

 

Otherwise, go through a scan, the same goes for making a 3D sketch and swinging a profile of your choice on it.

it's a staircase for 3D presentation almost the same model as the one in the photo -->

For the function you are talking about, you must first make the railing with a scan from a 3D sketch, then make an exstrusion of the profile of your bars from the center of each step.

You can attempt a repetition for steps where the distance is equal (from the 7th to the last), taking care to start your rung from the railing and using the curve of the railing as a curve for the repetition:

Draw your propeller and your straight parts, you convert everything into a sketch (in the same 3D sketch) and you put tube with the mechanically welded!

Basically, you can see that you have 4-5 identical answers.

 

So in my opinion, this is the right solution:p

 

Cheer up!

The problem is that I never use the Helix and spiral function as well as welded constructions :/

 

(I'm sharing with you the . STEP)

An example to help you! With that you have enough to start!!! SW2013 format!

When I create a Helix and Spiral curve function , it gives me this result.


Is it possible to choose the passage of the helix (once the sketches have been drawn on each leg of the railing to go through the center of them) to the top?

It's the starting plane of your propeller that will change at that moment, it's up to you to create it in the right place. The starting angle is also important!
