I’ll reply to your latest post first:
Well, believe it or not its the first screen video I’ve ever made. I knew I’d overrun a bit at the end when I couldn’t see how to turn recording off. And I had thought it was only about 25 minutes long. But I did NOT realise that in editing it to clip the end off, I had duplicated the whole thing! Will try to fix. Sorry it is a little blurry - I had to limit the resolution so it doesn’t come out several times the already large file size, and perhaps I should have reduced the Sketchup window size a bit further - I have a large monitor, and was only using a quarter of the screen or less. And there may have been further blurring during translation from window size to movie size.
When I said ‘flat’ I meant horizontal in the X-Y or red-green plane. That’s perpendicular to the blue axis, not parallel to it. Since i tend to start with a 3D model, THEN work out the size of the pieces it needs, I often have to rotate the pieces onto the horizontal - or ‘lay them flat’.
I take your point about saying what I’m doing with the mouse - the video records mouse movements and clicks, but not dragging with the mouse button held down.
Sorry to hear you are colour blind - see this earlier forum post for some suggestions to deal with that in Sketchup. You can’t (in any version so far) change the axis colours, but there are some workarounds suggested here: Changing the color of the axis. Or search Google for ‘Sketchup forum color blind’ (or colour blind).
And I really think you should invest a few dollars in a new keyboard if your Delete and Backspace really are broken - I can’t imagine typing without them!
I can’t see Doghouse32.skp yet in your posts, so will have to wait to look at that until later today or tomorrow.
But you are quite right about units of measurement. I’ll change them to inches only in Sketchup in future postings. I’m retired now, and of a generation that grew up with multi-radix arithmetic. It’s hard to imagine now, but I actually did sums at school like ‘If you buy 3 tons, 2 hundredweight, three quarters and five pounds of coal at six pounds, four shillings and eleven pence three farthings per ton, how much do you pay?’
And at the local amateur theatre in England for which I mostly use Sketchup, we still for historical reasons use feet and inches for our scenery, and make it using those measurements.
I can’t remember now how I worked out you were using 3/4" ply - i think as the difference between two measurements for the length of the floor and side or width of floor and end. And as you will be using 5/8 ply for sides and ends, I got it wrong anyway!
Even if your saw cut is only 1/8" wide (which many are) I myself would allow either 3/16" or 1/4" for the saw kerf, to allow for (a) wobbles in the straightness of the saw cuts and (b) an allowance for planing the edge straight and smooth after sawing. But if you use a straight-edge guide for the circular saw, and are content to sand rather than plane, 1/8" would do.
And on another practical point, I’d not usually specify dimensions any closer than 1/4" or 1/8" when designing, unless it has to fit something else, or is to make a right angle (like the height to the apex of the roof on the ends).
Can’t really say any more until I see Doghouse32.skp, which as far as I can see you haven’t yet uploaded.
Best wishes
