Malidctus

Thank you for the explanation. I'm not very well aware of the specifics of Lego construction, personally, so this is very much appreciated. I found a few more, actually, this time on a set I don't own a physical copy of - the MX-81 Hypersonic Operations Aircraft: The first one shows up on Page 52 of Book One. The previous several pages have asked me to create a fairly large structure which I need to attach "vertically" to some Technic pegs. It's difficult to explain, but the way the thing is designed has two half-peg/half-axle things (43039) fit inside two 15-hole Technic beams (64871). Directly behind the beams is a stack of several blocks. The structure also has a couple of 1x4 plates (3710) underneath it, supposedly coming down to the same "level" as the half-axel things. I presume it works in real life since it's in an actual real set manual, but it doesn't work in LDD. The lower plate collides with the block wall when you attempt to place the structure. In this case, the solution was simple - I removed the lower 1x4 plate and the thing fit like a glove. In fact, I have to wonder why the lower plate is even there, since it doesn't seem to serve any real purpose. The other shows up on Page 43 of Book Two. The previous page had me build a "windshield" structure, complete with a white shell (45705). That's the part with the actual issue, because the manual next asks me to lower this down on top of a triangular sail-looking thing (51000). The idea is that the narrow tip of the sail thing would fit into the hollow "inside" of the shell... Except it doesn't. Purely visually in LDD, it's clear that there's plenty of room in there, but the shell's collision box doesn't seem to acknowledge the piece's internal space, treating it like it has a solid flat bottom. I solved this by bending the sail thing "inwards," which allowed me to bring the shell down as far as the manual would want, but even then the shell was colliding with nothing at the far reach of its pivot. There was one other one, but upon revision, it turns out that was my fault. Oops!

And here's another one: The 8x6x2 cockpit window 98102 incorrect collision which extends farther "back" than the cockpit itself. When trying to recreate the Vermin Vaporizer (70704), it's impossible to put the window down to where the set requires it to go (as per page 66 of the manual), because the window collides with the wall it's attached to. It Visually, there's no reason why the bubble should collide, so this seems like an error. Now I have to redesign the cockpit because of this.

I found a couple, both of them from the Galactic Enforcer set (5974): One shows up on Page 11 of Instruction Book 2. I'm instructed to place down 5 6x8 plates (3036), with the front-most one lying over a pin connector with 4 Pins used to hold the support structure together. The pin connector is lying on its side one "level" below the plate, and there should be enough clearance for both pats. I know this for a fact, because I own the Galactic Enforcer and I've built it before. However, LDD believes that the pin connector is wider than it actually is and in so doing prevents me from putting the 6x8 plate over it. I had to replace the element in LDD with two long connector pegs (6558) so the model could be built. The other shows up earlier, on Page 29 of Instruction Book 1. Several pages ago (on page 26) I was instructed to secure two panel fairings (64391 and 64685 for left and right respectively) to two double-pin bricks (30526). On the actual Page 29, I'm instructed to place two 8x2x2 sloped bricks (41766) one level "above" the fairings. In real life, the sloped bricks lie just above the fairings themselves, touching them but applying no pressure. LDD did not allow me to do this, and in fact forced me to replace the double-pin bricks with a 1x1 brick (3005) and 1x1 brick with a hole (6541), connecting to the fairing by just one friction peg (2780). This meant I could tilt the fairing down by as little as 1 degree (it sits at 89 degrees now), making enough room for the sloped brick. Unfortunately, this leaves the fairing itself loose and prone to spinning freely and is inferior to the original design.

After having freyed my nerves to the bone, my wish list comes down to hinge/flex tools that actually work. To wit: An Inverse Kinematic way to drag hinged assemblies similar to the ability to drag flexible tubes. A Hinge Align tool which can actually align hinges instead of failing and forcing me to align hinges by myself. A smarter hinge system which allows for some give and part bending, and which doesn't lock up if a piece is held by two coaxial hinges (say, the drawbridge in Black Falcon's Fortress). A saner, less random means of controlling flexible elements. Preferably with the ability to control the absolute position of one end of the thing in three dimensions. As it is right now, I have two-dimensional control relative to my camera and no control over depth relative to it. More flexible flexible elements. As it stands, affixing the flexible tubes in my Galactic Enforcer is impossible because the pieces can't bend as much as my manual says they should. The ability to place bricks "in the air" with absolute 3D positioning without the need for them to snap onto something. Lacking this ability makes placing the control levers element in my Millennium Falcon impossible because it doesn't snap onto anything. It's just held in place loosely by other elements. An auto-save feature.

I sincerely hope this is the right place to post this, but I've been looking for a couple of part in LDD all day, and I just can't find them. But for different reasons. Both Bricklink and Rebrickable agree on the numbering and namingm but LDD does not. One part is 4262, a Lego Technic "Plate 1 x 6 with Toothed Ends" which is essentially four studs and two peg holes on the sides. LDD does have a part with that number, but it's "Hoved 2 w/ball cup 09" and it looks like something out of Bioncile. I did try searching by name, but this shows up for 1x6 or 6x1 or "tooth" or "teeth." A manual search of everything revealed nothing, though I hope I just missed it. The other part both sites call 4265a, which I'm pretty sure is not an accurate Lego designation. Nothing shows up when I search for it. However, both sites call it "Bush 1/2 Toothed Type I." I found the actual Bush 1/2, it's where you'd expect (under the pegs section) but the toothed version doesn't seem to exist. Both of these parts are required for set 8816, the Lego Technic offroader. I actually own the physical set which has those parts, which led me to believe they were pretty common back when I was younger. The toothed bushing is necessary for a few axel connections as it locks onto other toothed elements to prevent pieces from rotating freely and the toothed plate is necessary as it's used as the central connector to the set's steering system. Neither part seems to exist. I've run into incorrect numbers before, most recently when recreating my Millenium Falcon where the cocpit cone pieces were numbered and called something else (with "Falcon" appended) but LDD had identical generic pieces which I could use. In this case, I can't find anything even remotely close anywhere in the inventory. And yes, I'm using the LDD Extended theme. The parts just don't seem to exist, and that's a concern.
