10030 Imperial Star Destroyer, I draw this sketch before try to build it. It show that the ideal angle for all hinges is 17.95582373°. But It's impossible to perfect build by normal method because: 1. The hinge at the middle (14 and 2)will not connect. 2. the side bar is 87.89766777 instade of 88 studs long . The left side of the LDD model proof these.(I input 17.95582373° with hinge tool then it become exactly same as the sketch, see lower-left red circles that's 0.10233223 come out and can not connect). We know that LLD allow a very little bricks collision. but by normal move method. The minimal move step is 0.1 Studs and that is too big for allow the collision. In this case we have to 1. make the side bar 0.10233223 shorter but also within collision allow. So I divide it to 0.02046645 x 5 collision places then it works! LDD allow those collisions and I got a 87.89766777 studs long bar to do a perfect assembly(perfect both angle and length). 2. Precise move the middle hinge so it can connect to both side bar and center bar. The result show on the right side of LDD model (red circles). The right double bars are copy form both side then connect at far end to show that they are 0.10233223 different in length (red circle).

This is one of the 18 functions that I was post in the topic "LDD 5, what do YOU want?" http://www.eurobrick...dpost&p=1073211

#9. Move select brick to any direction x/y/z by input number.(stud units support decimal)

#7. Tool to apply allow collision property to selected bricks.(can build model that use flexibility of real brick, Why limit ourself and give up the advantage of virtual)
