Structural design of Plexiglas

[s.d.m]

Good day!

How to use Autodesk Inventor for design a bulk structure, representing a surround frame, glued to each other facets of plexiglass? Example - in the figure.

The purpose of the design - to get the contours of parts of this construction.

Some conditions:
Sheets have a different shape. Joints are made of sheets at different angles to each other. Docking sheet is made individually in each face / top.

On what steps to go in the design?

Sorry for using google translate!)
Thank you!

Can you attach the ipt file here?
What version of Inventor?
I would either do as multi-body solid Thicken each sheet
or
do as single solid and then Derive Component - Body as Work Surface for each sheet and Thicken sheets as needed.
