Looking for help to produce drawings of curved raked glass


I have been trying to draw QTY 5 panels of glass that will fascia fix to the side of some curved steps and am struggling to do so.

I have drawn the plan view of the proposed lay out and made several duplications trying different methods and also watching many you tube videos but am starting to get really stressed out with it.

I am looking for some help!!!

I can send what I have done so far and if some one can point me in the right direction it would be greatly appreciated.

Many thanks


If you have an image of the glass panels and steps, post that so we can see what you want to accomplish. If you’ve already tried something in SketchUp, post that, too.

I have attached some PDF sketches showing what iv done so far.

I have downloaded 1001bit pro hoping there was a tool that would help but I still cant figure it out,

How about uploading your SKP file?

as you have the outline drawn you could try “curviloft” to skin that and then “joint push pull” to thicken?

There are many ways to do what you want. The very basic one is to create a cutting plane where you want it and chop through.
This is a very simplistic version.
By the way, in future it is better to add .jpg images directly to your post.

If you want the same at the bottom, just copy it down.



Thanks for the replies, I have tried cutting a plane but due to the steps being curved I cant achieve 900mm above the toes of the steps.

Thanks for this, I am going to try this out. I’ll post my results

If you offset the front corner of each step along its adjacent glass panel the height of 900mm, (use the ‘Tape Measure’ tool) you get guide points that indicate where the curved top edge of the glass needs to go through. There might be a plugin that stitches them nicely into a “smooth” curve of connected edges (something like a bezier curve).

I did say there are many ways and that this was a simplistic demo. The cutting plane need not be flat.
So here is a very manual version.


not a very well modeled stair, but to show idea of curviloft skin (as you already have a profile) and joint PP to thicken.

Here’s another simple option. Using Thomthom’s Truebend.

In case you are wondering, this is how that looks in plan.


Man that was embarrassing how long that took me :sweat_smile:

Thank you for all the help!!!

Its still not quite right :anguished:

Ok I finally have the five panels to the correct dimensions and the model is looking good.

Now I need to try and flatten the panels to create patterns, is there a simple way of doing this?

I have found the Extension Unwrap And Flatten which seems to have given good results.

Looks like you are doing well.
Here are a couple of other tools you may find useful.
Curvishear from fredo to create the curved slope for you.
Extrude by Vector from Tig to pull the shape up.
Jointt pushpull from fredo to give thickness.

This gif is very basic, but you see me waving my mouse about on the bottom edge, this is telling you that you can split this edge up into the various panels you want and make a gap between then then move them up into place and use extrude by vector to create individual panels with stepped straight bottoms. You’d just need to delete the little edges that join them together at the top.

Stair Vector


Yeah that would of saved me so much time,

The problem that I was having was creating a cutting plane from toe to toe because it was segmented on the edges. this meant that when I intersected the line with the glass it didn’t cut through the entire object.

I ended up dividing each step into smaller segments to create a smother section that followed the radius of the steps more closely.

essentially doing what you’re showing above but not as efficiently, less meme more feature length movie ahahah. Still I got there in the end.

So this is the top 3 panels flattened.

I transferred marks from each toe of the steps onto the glass whilst it was still curved and positioned on the model.

Then when I flattened it I could determine where the holes can go in the glass for the glass clamps maintaining my minimum edge distances for both concrete and glass.

That looks very good. Well done.
