How to do a sketch-driven rehearsal

Out of category

Hello

I would like to do a controlled rehearsal (steps) by sketch to create a spiral staircase (in a multibody).

I am attaching  my document.

If someone has two minutes to explain to me how to do it, I would be delighted :).

Thank you in advance.

In theory you should find what you are looking for

Hello

 

The basics are good, just one element is missing.

 

To put it simply, create a volume from your spiral starting circle.

Then use this volume to create the repeat.

Then just hide this volume and you're done! ;)

Thank you for your tutorials, but it doesn't help me.

My problem is really the repetition according to a helical curve. Impossible for me to select a normal face to the curve. 

A different question:

To design a spiral staircase (helical), do you go through a room (multibody) or an assembly (shaft/steps/railings/etc.)?

Hello

not easy without going through the surface area

No need for a surface area.

I did it with a classic boss, it works very well

 

On my image, you can see the normal side (<1>)

if you transform your helical sketch into a 3D curve

it does it without blemish

By turning it into a 3D sketch you can do it Gt22?

Do you have a screenshot?

Yes, indeed the principle is the same I just extruded a construction surface instead of a volume body

Yes, it comes down to the same thing, you just need one face that follows the curve

I tried out of curiosity with the 3D curve and didn't succeed, because you have to designate a reference face.

This tutorial can help you with 3D sketching:

Perfect Bart :) nikel

But why can't we select the rounded outer side of the step as the normal face of the curve?

Thank you all

You can't, because the face you select must absolutely touch your curve

If your curve starts at the end you could have selected the sheet metal face.

I guess the curve is the line of passage?

 

Otherwise you have to draw another curve following the first one starting from the end of your step.

Yes, it is indeed the line of passage. But ok, good explanation, thanks again:)

Otherwise it was just enough to shift the helicidal curve, see attached

here is a walking repetition via a 3D sketch ;-)

Yes, it's a 3D curve driven repetition, but apart from the sheet metal module... We have to do a body respite
