Question

Close curved sides in sheet metal in CREO 9.0

Hi,


How do I get the final shape in the attached picture? I want to "weld" the edges together. For me it's irrelevant if it's done in sheetmetal, by surfaces or any other method. All I want is the finished shape and sheetmetal is maybe a way to go. The only thing I know is the dimensions when the panels are flat. The finished height of the container will be less than the length of the panels due to the curvature.

 

Fist time here and hoping for some tips 🙂

It is easily built using surfaces if you are just looking to replicate the geometry of the picture.

 

Create the base and then one vertical wall. You can then pattern the vertical wall and merge all of the quilts together. Then thicken the quilt to get a solid model. The surfaces are all planar so you can sketch the shape and then use the fill command to create the two required surfaces. See the model tree below. The pattern is an axial pattern using 90 degree increments.

    I was maybe a bit unclear. I'd  like the finished part to look like this. Thin walls or solid doesn't matter. I will only use the outer geometry.

    What do you need from the CAD model? Will you actually be making this from metal and welding it? If you are fabricating this, do you need the flat pattern for 5 pieces?

    Since you have the blank and want to create the shape that it would form, Here is a sketch that I would suggest:

    In this example, the center base is 100, the radius of the sides is 250, and the length of the blank sides is 225.  I used perimeter dimension of 225 to control the resulting height.

    Perimeter is a good tool 🙂 Much appreciated your help! I wish it was that easy 🙂 I think I simplified my example a bit too much. This is more what it is about. Apart from this the top is angled and formed as a trapezoid and bottom is a rectangle. The real thing is more like this. Know the length of the edge but as you can see it's not oriented in a plane 😞 I must, in some way bend plane surfaces with known geometry to each others edges.

    Perimeter can be used to control the length of multiple curves.  The hard part in creating the model will be accounting for the thickness and bending stretch to get finished shape from the blank.
