Assembly joint to use to attach base of a asymetrical tray

[msmithN98TT]

Attached tray is 450 depth in one corner,  475 depth in 2 diagonal corners and 500 depth in corner opposite the 450 corner.   

I have worked out how to create a plane using 3 points.

I can orient to this plane using align

To fix the base into the assembly I have used Rigid group.

Is there a way to create a joint but then orient to a plane or something similar that doesn't need me to zoom in to create a model with a 'best fit' that will be a few microns out.

I have attached the drawing  for others to see.  Below is the asymetrical 'frame and base i want to join

1. You imported (sketch) geometry. That has some inherent dangers and it unlikely is going to make things quicker.

2. You then moved bodies within components  (usually not a good idea for beginners) and using the sometimes components and then used the Capture Position feature to hold them in place. It doesn't. and that is not a recommended workflow.

3. None of your components are properly joined.

I'd venture a guess that it is faster to re-design this from scratch with the native tools in Fusion using configurations .

I would recommend to complete one of the free courses created by Autodesk for new users here:

Many thanks for taking the time to look at this.  I agree -  my discipline in this drawing is very poor on this -  reason is I drew the cut pieces in 2D cad to cut them on cnc.  I worked sizes out in my head with pen and paper.  I slapped them together in fusion just to check for any mistakes!  This was when I could not find a way to attach the base 'in plane' to the sides.   I have redrawn this in the way I probably would have done had I drawn this 'properly'.  Any critique still appreciated 🙂  we can all improve (self taught)   

usually I like to create single components in fusion (seperate files) and then assemble them in a new design using joints.  I found that due to the offset plane the bottom is on,  I couldn't find a way to assemble (using joint) the base component to the rest of the assembly in the right plane,  as it is rotated in two planes.  

Thanks again

For this design, the top-down design method (design in place) is what I would have used. 

If you need to arrange this to be able to cut it on a CNC you could use the Modify -> Arrange feature.

I have not used this yet, so I cannot speak about it, but here is a link to the documentation.

In order to use that feature, the solid bodies in your design have to be converted to components. Once you've done that, you should shift select all of the components, right-click, and ground them to the parent.

To make variations for the different sizes, I would use Configurations (paid subscription feature).

It is best to assign user parameters to all the dimensions that change for the different sizes. and add those to the Configurations table.

Then it is very easy to create a configuration for each. Just enter the different dimensions into a table. No need to model each variant separately.

A couple of your sketches are still under-constrained. Especially the Bottom sketch.
