First, Job Setup:

Set Background

Load Image

Drag into position

Draw a rectangle of the right size as a size check:

and it’s obvious that the drawing and dimensions do not match up…

Instead, draw a series of overlapping rectangles using the specified dimensions for each part:

and additional rectangles as needed for spacing:

and positioning:

Once all the elements for a given part are compleat, select them:

and Boolean Union:

OK

Repeat for each other part.

As one draws, correct dimensions as necessary.

OK

which doesn’t quite line up, so we re-draw the front/back outline:

Delete the wrong construction:

Duplicate the original:

twice

and drag both into registration:

select the re-drawn geometry:

shift-click on one of the duplicates to add it to the selection as the key object (indicated by a dashed highlight)

then use Boolean Subtraction:

to remove what is not wanted:

OK

Repeat for the other side:

OK

Hide the background image:

OK

Duplicate the front/back:

Verify that things fit as expected:
