Spiral Problem
-
Hello !
First of all, I'll introduce myself : I'm a french newbie, so excuse me if I mispell words or if my grammar seems a bit strange
Here comes the problem : once again, it's a spiral staircase...
I already searched on the net for a Ruby script and I found DrawHelix1.3, which is not bad but does not allow me to make a clockwise helix. So I settled on my own to make my oh so difficult spiral staircase, and now I'm stuck. I just can't make a face and a curve intersect properly, and I can't understand why.
Here's a few screenshots, I hope you can see what the problem is.[img=http://img296.imageshack.us/img296/967/picture3bh9.th.png]

Any suggestions ?
PS : Here's the staircase :

Hi Swak and welcome to the forums!
To make a clockwise spiral, make one with the helix rb and flip it about either the green or red axes.
Now as for the staircase; I'm not sure what exactly I am seeing in those images. Are you trying to fill the face uunder the steps and with the spiral runnung under them?
For the line not being part of the face in your first picture: 1) make sure it is ON the face, 2) select both and right click > intersect selected. It should work this way.
BTW: nice staircase!

Hi, thanks for your answer.
What do you mean by flipping it ?
The way I see it, it's making 180° with the "Rotate" tool on the red or green axis with the spiral selected as a component, which doesn't work since it's a spiral
I end up with the same one I originally had.What I meant to ask was, is there any way to "cut" the curved face along the line a drew on it (which can be almost on it, I'm not sure, I suck at math) ? I'd like the bottom of each step to be smoothly aligned on the spiral, if you see what I mean.

Thanks again

Dear Swak,
Use a cutting plane, and then use Interest (right click) to get the cutting plane to cut the curved surface. The attached has the cutting plane and curved solid as groups. You can get the plane to cut the group by editing the curve group, selecting all inside the group and then Intersect>Intersect with model. Cutting lines will then appear on the curved surface.
Hope this helps.
Regards,
Bob

Thanks a lot, that was exactly what I was looking for !
I can finally finish that d***** spiral staircase -
Just to clarify Gaieus' suggestion of using Flip to get a clockwise spiral. Flip is not the same as Rotate. Flip produces a mirror image (not a duplicate)...so left becomes right and right becomes left. That will change the direction of rotation.
