Use rope was added due to those tiny little ropes you used to get in the old Lego models. Mostly they have been phased out but you still see them in winches from time to time. I can really take or leave use rope as a skill in there so don't mind leaving it behind at all. That leaves 9 skills for a 4 + int class. Most people are going to have the majority maxed. That's not always a bad thing though.

Brick Construction
So you can make and deconstruct with no penalties, sounds alright.
Bonus to Craft = to level, also good. Though does Craft give any bonuses from having a really high score? Looking down in Models it doesn't look like it. It only gives a cap on the number of bricks used (which is somewhere in the thousands, limiting the bigger and more expensive options)
Even a portable device has a DC. Say you wanted to make a ranged weapon with the rapid reload feat and 2 minifig seats. It would cost 300+200+300+200 = 1000 bricks
That means it has a DC of 20 to create. I'm not saying this is a huge DC, but for a weapon that is viable to create at level 1, the bonus is nice.

The Brick-Builder can salvage another's lego Model's with a Disable Device check, DC Brick-Builder's level. So a 10th level Brick Builder has a DC10? Or did you mean 10 + Brick builder's level. Because sinking one rank into Disable Device lets you pretty much auto-salvage any other Brick Builder's things.
Yep mistake, fixed

Construct Minifig
3 Silver pieces for a Minifig *level
At levels 3-8 you will have a swarm of them, simply moving them from room to room would take minutes of commanding but you will never run out.
And since it's a +5 only when needing to make a Concentration check the Brick Builder will take control of the Action Economy with a swarm of 40+ Minifigs. Which (at level 5) cost 1.5 GP, so 60 gold.
There needs to be some sort of limit, a Hard cap (not a soft one, or one that only applies some of the time). Maybe 5 + 1/2 level?
The hard cap is there. They can only control a levels worth at once. It doesn't really matter about the uncontrolled ones, they are inert and just do nothing.

Other Bricks:
Who would ever use a Light Brick in a weapon Or at all? 1d6 extra Fire damage is nothing, it's much easier to simply use them as inexpensive Torches or just never buy them at all
The same goes for Sonic and Power. Maybe not Power when there are things that require it to function.
Soul gets the same pass as Power in that there arent anything that needs power
The damage does scale (albeit slowly) as you go up in level. Plus the status effects it can create are all staking. A fire arrow created from a light brick at level 20 does 3d6 fire damage, a chance to cause deafness in a target for 3 rounds. A Fortitude Save, chance to daze a target for 1 round. A will Save, a chance to kill a target. A Fortitude Save, and is considered a ghost touch weapon. For 20 gp. That's a lot for not much. In fact I am considering this may be too powerful.

Improve Minifig
Needs filling in
Yes it does. Working on this one is the most time consuming.

Animate Minifig:
Starts at 2, goes up to 10 by the end of the class, since they follow instructions they would best be used in repetitive tasks every round (like Reloading) but their lack of numbers makes Animated Minifigs valuable compared to the expendable Normal Minifigs
Either more of them, or make it a basic upgrade to the Minifig would be best (maybe an optional add-on that adds to their Pile of Bricks if you implement that feature onto them?)
This is a hard one. On one hand I feel that all your minifigs should have this. On the other, I think this ability has the most potential for abuse.

Heroic Minifig:
-5 Character level is good, when having 4 Cohorts it can get OP if too close and useless if there isn't enough class levels to make it competitive
I do like the change to Character level instead of Brick Builder level
Yeah brick builder level wasn't enough for multi-classing. It's like having a liability hung round your neck.

5 Autonomous beings at any 1 time. Discounting your 4 Cohorts of course.
This number should probably be bumped up.
This is similar to the Animate problem. I may have started too harsh on the ability, but it was to try and ensure my homebrew wasn't a win everything class. Expect both to get reviewed later, once I've finished the improvements.

Body of Bricks:
Can you list the traits considered a positive and which are 'drawbacks'?
And 100,000 bricks a day is generating 10 Million GP of profit by selling off Soul Bricks. Maybe add an addendum that the bricks may only be used by you to create Lego Models and not sold off for money. And reduce the number of bricks produced (maybe also increase GP-Brick conversions and reduce some of the larger costs of Lego Items)
Sure I could list what I think, but why not let the person who gets the ability decide. Also I will clarify, the bricks per day is regular bricks, not soul bricks. I'll also clarify in the OP.

Minifigs: What advancement do the little guys get for their HD increase? Construct traits? What level do they grow in size if they do at all
They already have construct traits, and minifigs don't grow in size. I haven't decided to do technic men or whatever they are called. Just sticking with minifigs for now. Any increase in hit dice gives them a construct hit die. All the info can be found on the SRD, but I will link it in the OP and here

Minifig Armour/Weapons: Do they stack? Can one apply Minifig Armour twice to gain a +4 Nat Armour for 2 Bricks? or 2 Weapons increasing the size by 2?
No they don't stack, but weapons and armour never have in D&D. Do I need to make that more clear. I thought it was clear enough.

You do realize it requires a base 110 Craft check to make a basic Vehicle right? 10,000 /100 = 100. 100 + 10 = 110. And to increase it by 1 size adds 900 to the craft DC.
And even if it didn't, where would the Builder get upwards of 15k bricks for a good vehicle before lvl20?
And why is the vehicle speed stuck at 40ft? and Average maneuvering for the fliers
Yeah the DC is way to high here. Probably the cost too. Expect a review later on vehicle construction.

Weapons: 1 brick/shot is a little much. Maybe 1 brick /quiver? with the quiver having 10 shots in it
Actually 1 brick per shot is the same cost as the price for arrows. That is how I ended up pricing the regular bricks in the first place. Also see above for the power of the special bricks.

Skills: So it has max rank -3 -multiclassing? Right up until the Builder multiclasses or hits 20 they will have a full assortment of independent Skill-Minifigs running around doing the whole range of skill-assortments
Yes they could. If they were going to invest that heavily in the skills. I could limit it to physical ability only skills, but I think I'm going to let this one slide. The only way to limit this would be to make it only an Aid another check. I can do that but I don't feel this function needs the nerf. Am I wrong here?

Feats: 30gp +30gp/feat? Yes please. Especially when I hit lvl21 and get the prereq for Epic spells. Hellooo Bracers of Perfect Two-Weapon Fighting, Epic intelligence x10 and as much Toughness as I want
Each portable device can only have 2 functions. Each feat is a function. the best two weapon braces you can buy are Improved Two-Weapon Fighting. Sure you could have a vehicle with perfect two weapon fighting, but how are you using those feats while driving the vehicle. You can't even use the braces to get another model to have the prerequisite feats. I'm not saying the models are a perfect system, but with some minimal DM intervention I think the feat section works.
