Hello friends :) To begin, I have tried searching for this in the Forum, but if it's here already, my apologies and put it down to inadequate navigation on my part!
What I'm going to talk about seems to mostly affect models designed using computer programs; at least it does on the last ones I've built, and the one I'm doing now. In the pic you'll see a shape, Fig.1; it could be part of anything but it'll serve.The issue is two-fold really.
Firstly, whether by intent on the designers' part, whether it's part of the program used or if it's done to impart strength, I've noticed that frequently parts like Fig.1 are broken down into several sections, as seen in Fig.2. My maxim is to keep things as simple as possible, so the part would be just one piece of card, or as few as possible on the paper size used, so a child could build it.
Secondly, and this is the bugbear, the program obviously deems it sufficient to 'plan out' the four individual pieces seen in Fig.2 at absolutely the correct outside dimensions. Which is fine and good in the world of electrons on your screen, but by the law of cumulative error, there are now four thicknesses of folded card on the top sections, as well as any tabs that may have been added. Added to this is, the chances of cutting/folding errors on the part of the builder have also been multiplied four times. It is obvious, then, that the three segments on top will be wider than intended when assembled. It also follows that the more bits like this stuck together, the greater the error, to the point where things simply don't fit anymore. At least, that's what happened to the models I was building.
So, please tweak things to accomodate the thickness/es of the cardstock and/or tabs, and it would be very helpful if each designer annotated their models with the weight of cardstock or paper used so I'll know if it needs building from writing paper or old cereal boxes :) Lastly, I have no idea about programs that 'unfold' or flatten designs (or even what the correct terminology is!) My PC cannot spare the RAM, and I like geometry, maths, rulers, compasses and, above all, trial fitting everything so I know it all fits together.
