Well, I can open the file fine, and see the parts laid out in a way that will fit the sheets, along with my draft Doghouse.
I’ve copied all of your parts into a new file.
I opened the Outliner window to see what use you have made of Components.
Some of your parts are components, like Back, Side L and Roof L. Some aren’t, like the areas labelled Roof R, Floor, and Side R.
So the first thing I would think to do is to make these areas into components too.
But even before that, I’d take two other steps - it will make life easier .
First, as originally recommended, draw an 8x4 rectangle, make it into a component, copy it to make a second and place them a short way apart - perhaps a whole foot. LOCK them, so you can’t later mess them up, resize or move them accidentally.
And second, DELETE all the dimensions. It will be harder to do later (I know, I tried, and eventually succeeded, but it wasn’t easy - the thickness of the components partly obscures them and makes the very hard to select).
THEN make all your pieces into components.
The easiest way to do that is to go to Top view in Parallel Projection - see my first reply for how to.
Then drag the mouse from bottom left to top right to surround one of the areas that isn’t already a component. That will select the face, and the edges around it, (and would have selected the dimension text too, if it were still there).
Start with Floor - it’s the easiest to drag the mouse around.
Or you can double click the Face anywhere inside the edges .
When ALL the elements of Floor are highlighted (turned blue to show they are selected) press letter g on the keyboard (without the shift key) to Make Component, and give it the name Floor. It’s useful to open the Entity Info window (either R-click on the selected element, or go to Window/Entity Info).
Then do the same for all the other areas that aren’t already components: Side R, and Front.
Save the file, in case of accidents.
I can work out from the dimensions that you will be using 3/4" (19mm) ply. And your draft floor is 2’8" x 2’4 5/8". So start on another part of the Red-Green plane, now in Camera/Perspective view, and copy the floor to there. Double click it to open for editing, then use the PushPull tool to give it thickness - 3/4". Press Enter after typing the thickness. You’ll see the original Floor component get thickness too. And the dimensions would get obscured - but you’ll have got rid of them by now.
Now draw the inside of the doghouse in 3D.
Start by drawing a rectangle over the top of the floor. Then PushPull it up to the inside height of the side - Side height, less 3/4" (so 1’ 6 1/2.
Draw a line down the ridge picking Midpoints on the short side with the Line tool (shortcut L). Change to the Select tool (shortcut SpaceBar). Highlight the line you just drew with a single click. Use Move tool to move it up about 10 inches (you don’t have ends drawn, so I’m guessing the height for the moment.) Make sure you move straight up on the Blue axis by tapping the UpArrow key after Move, after the first mouse click on the line. Or just watch where the mouse goes, and see that you get the tooltip ‘On Blue Axis’. To get the exact height, I guess you may intend the roof to have a full 90 degree right angle at the apes, so you can draw a construction line with the protractor tool at 45 degrees from the eave line, and move the ridge line up to that.
Triple click on what you’ve just drawn, and make it into a component (‘g’ shortcut). Call the new component ‘Inside’ or something similar.
Draw a rectangle on the near side from the eaves to the bottom of the floor. Pushpull it towards you to 3/4" thick.
Triple click what you’ve just drawn and make it a component. Call it Side (not yet L or R).
Move a copy of the side to the other side (M plus tap Ctrl). Pick the near bottom corner for the start of the Copy and move it to the far bottom corner of the floor.
Make Roof L component 3/4" thick (see above for Floor). After you’ve chosen the PushPull tool, you can double click the face to give it the same thickness as your last PushPull, 3/4".
Now Copy the near bottom corner of the Roof to the top near corner of the near Side, then Rotate (shortcut Q) about the Red axis. You want to rotate it around the FAR corner of the side, to raise the roof to the correct angle running through the ridge line. You’ll see that you will need to bevel the top edge of the Side at 45 degrees after you’ve cut it out.
Move it down the slope line a couple of inches, or a bit more, to give an eaves that will shed water. You’ll see that it is still too big unless you make the overlap a full three inches.
If instead you were to make the Left roof panel 3/4" wider than the Right one, you could make the eaves overlaps equal, within the width of a sawcut.
Anyway, you can now put on the Left roof. Make a Copy and position its nearer bottom corner at the top near corner of the Roof R piece. Rotate it down 45 degrees.
Now you have what looks like a complete dogouse, but of course its front and back have no thickness.
To fix that, use the Line tool (L) to drawn round the nearer end, choosing whether to overlap the sides and bottom, or go inside them. I chose to overlap.
You may need to orbit round the model (easiest with a three button wheel mouse, or use the Orbit (O) and Zoom tools (Z), so you can see all five corners - either all at once, or in turn.
PushPull the end to 3/4" thick, then make it a component called (say) End.
Copy it to the other end. And you have a doghouse. Now all you need to do is make a door at one end, a suitable size for your dog.
To see if you can make it all at this size from your two pieces of ply, there are a few more steps.
Copy the End, rotate it flat, and use it to see if you can fit two onto your plywood. And copy one of the sides in the same way, rotate it flat, make another (flat) copy, and now you have all the pieces to move around and see how they fit.
Looks as if you have PLENTY of plywood - now you can experiment with the 3D model, re-sizing some of its components, seeing the changes immediately on the cutting layout (you’ll need to move them around after resizing) and adjusting until you are happy.
To begin with, I’d ignore the saw cut width - just place the pieces touching each other - but remember to leave enough allowance for sawcuts afterwards.
I’ll try to make a video of the steps an upload it later - as I have never done that before, it’ll be a good thing for me to learn.
When you have finished making adjustments to the sizes, and refitted them on the ply, NOW you can dimension them and label them.
As I suggested before, draw the Dimensions and Label text on a new layer.
I’ve used a slightly different layout, which will allow you to make the doghouse bigger, if you want to. I’ve put one roof piece and one side piece on each sheet.
And I’ve flipped the Side pieces along their blue axis (they were drawn upright, so the blue component axis is the green ‘world’ axis) and the far End along the green axis, so they’ll grow into the ply if you resize them in the 3D model.
This is what my drawing looks like now:
And heres’ the model.

I’ll post later about how to resize the elements in 3D and see the effect on cutting layout.
