Bend Stairs to Curved Wall

ryangarnett

I can't do that. I work with real data, building features collected from stereo imagery, so I don't have the luxury of making buildings with "fake" values. I have to use the data that is provided, hence the curve to wall issue.

So your real data for the tank indicates the number of sides you must use to draw a cylinder? Well, then make the steps longer so they extend inside the cylinder and cut them off at the wall of the tank after you've placed them.

Why do you keep trotting out new details with each post? We have no way of knowing all these things unless you tell us.

ryangarnett

Here is a sample of the tankers I need to model. So the "building" or tank with height will be provided, but I have to add the detail (stairs). And as you can see in the picture, the stairs "snap" to the side of the tank and do not overlap.

I'm not trotting out new detail, its in the post "to curved wall". You are proposing changing my wall, so I am providing you the information as to why that won't work.

Just asking is this close to what your trying to do?

I used shape bender.

ryangarnett

Yes that is exactly what I am hoping to achieve. When I have used Shape Bender it lines the stairs up wrong. Would you mind sharing your steps, etc...

Thanks...

I assume your referring to me.

Okay I made a tutorial, I hope I did it right first time making one.

FYI: I used TIGs ArcBy plugin to make the arc.

TIGs ArcBy...
I used the "Radius+Length"

Type in radius of the cylinder
Type in length of the arc
Change number of segments

Thanks Spreadcore...I will try that for sure....Thanks again...

Thank you spreadcore...that tutorial was perfect. I didn't know that you had to have the stairs the same height, and that the straight line needed to be the same length as the rise. These were then things I was missing.

Thanks again....really helped!

Your welcome, glad it worked for you.

FYI:
The straight line needs to be the same length as the "Run" of the stairs.

The "Rise" is the height of the stairs.

Thanks again...
