Changing wall thickness of a box

[terrypin 3]

Without finding and editing the original SCAD file I want to change the wall thickness (i.e. the thickness of each of the four sides) from its original 0.8mm to 3mm. (To keep it simple I've used 3.2mm.) However, after overriding the profile by making this change, why do I not see any difference in the display of the walls?

...because what you've changed is a setting of a printing profile.

It's not a geometry modifier.

Your idea would only work, if the model is a closed box, but not if the walls are already present as geometry.

 

Cura is slicer and can scale and mirror loaded models, but has no further tools to modify the geometry.

What you want to achieve is a classic task for a CAD-Program.

 

If the geometry is as simple as it looks like - all you need is a simple cube (of any size).

Then scale it to the correct size and everything else can be done with profile settings (no infill, no top layers, bottom- and wall thickness as you like).

Thank you. I think I grasp what you mean. Essentially that the walls are fixed so prevent any thickening of the walls, yes? But why then does Cura appear to offer the option at all?

Yes - as i said - the geometry of the part is defined by the loaded model. Cura does not change this.

 

What you probably call a "box with walls" can also be seen as "cuboid with a cavity"...

 

The term "wall" has a different meaning in Cura.

Think of a "wall" in Cura as the shell around the given model.

Or translate "wall thickness" to "horizontal shell thickness" if you want.

 

It's easier to see for models without cavities but the principle stays the same:

I'm not sure, but you can perhaps achieve something with the "expansion" settings. Perhaps in combination with the scale tool... dunno.

 

It's no replacement for a proper CAD application, but it's at least ...something 🤷‍♂️
