Hi guys, i need some help with something that i'm trying to do.

I have two arched shaped pipes which i have created using the pipe along path tool. These two pipes meet at the end point as can be seen in the images. I will be 3d printing these separately and gluing them together, which means i need the ends to be flat at 90 degrees so i can just butt them together, however, as you can see, when you have an arch shaped piped, the end face is perpendicular to the line which i have piped meaning i now have 2 angled faces.

In sketch up it's fine because you just overlap them and they create a solid object, however, given that i will be printing them, i need a face which lines up perfectly.

The last cad drawing shows exactly what i mean. The first one is what i have and the second one displays what i need.

Thanks in advance

I can't believe how easy that was. Thankyou!

This might be a very stupid question, but I'm building a model for which i will use to 3d print and i have drawn the model at 1:1 and need to scale it down to 1:300, however, when i try to use the scale tool it never quite does the job.

I am using one part of the model as a reference which is 300mm at 1:1 and will need to scale down to 1mm @ 1:300 in order to print correctly, however, whenever it gets that small the model messes up and i can't zoom in close enough.

I've tried scaling the 1:1 model by inputting 0.001 and it gets way to small to do anything.

Any help would be appreciated.
Thanks

The model in the sketchup warehouse is actually the one i did use, however, it's not detailed enough to print off because it's essentially made up of lines and surfaces, which aren't suitable 3D printing because they are not solids so I'm modifying it for accuracy.

If i can send you the file, it would be great if you could show me how to do it. Thanks heaps.

Hi guys,

Ok so i'm trying to build my first 3D printed model and it's a football stadium with a shell roof so due to the geometry involved, i thought 3D printing was the way to go.

Now i know that everything needs to be a solid in order to 3D print however the roof beams i have are interconnected pipes. As you can see from the first image, i started with simple lines which i turned into pipes by created a disc at one end and then using the 'follow me' tool, i made a pipe. I did this with all of the lines and they pretty much interconnected. When you delete the surface of the pipes, you can see what the ends look like as well. The second image shows you the pipes.

When i use the 'tube along path' tool, the pipes don't fully connect and it leaves gaps like the third image.

These pipes will form the roof structure and i will cover it with cladding such as image 4.

I have two problems here.

1. When i run 'solid inspector', it tells me the ends of my pipes(where they connect) are not solid as you can see by the oranges marks.

2. In order to create the cladding, i need to draw a line directly in the center of the surface of the pipes and connect them in order to create a triangle surface, which i will then extrude using 'joint push pull' (because i need to turn the surface into a solid). See image 5. The line needs to be in the center of the pipe because the cladding needs to sit directly on the roof structure and not accidentally be hovering in the air.

Essentially i want to create a roof structure out of those pipes which all need to be solid for 3D printing and then cover it with those triangle panels and it all needs to be one solid object.

If you're wondering whyi need the pipes, it's because they will be visible from the inside. You can see the model of the stadium I'm trying to build.

I need to get this right because i need to do a test 3D print and the model is 1:250 so it is quite large and will cost me too much if i make mistakes so any help would be appreciated.

If anyone's curious about what stadium i'm building, it's called AAMI Park in Melbourne.

Thanks heaps

Thankyou so much. That did exactly what i wanted it to.

Hi all,

I'm creating a design for 3D printing and i have a roof which has hexagonal surfaces as you can see in the images. What i want to do is pull the surfaces in order to give them thickness for 3D printing, however, due to the angles of the surfaces, when i do pull the surfaces, they do not join and i get something like the second and third images with gaps in between.

The only thing i can think of is a line in the center at a particular length and join the edges to that line, however, i don't want to do that because its too manual and i don't know what angle to draw that line at so i'm hoping there's an easier way.

Any ideas would be appreciated.
Thanks

Usually when i render i zoom into whatever part i want to render and then hit render and it will render that specific section, however, now for some reason, when i hit render it's giving me a greyish, blueish blank page and my building is nowhere to be seen.

Why isn't it rendering my scene?

Oh awesome, thankyou!

I want to create a slab similar to the one in the image i have attached so i can create a slab in that shape, however, i don't have a spline tool in order to create that shape.

The closest thing i can do, is use circles and trim, however, that doesn't give me the same shape.

What plugin would i need to dl so i can create those odd shapes?

Thanks
