Hinge help

[soccerkid6]

I'm trying to build rafters for a roof on LDD, that I have made in real life. I am doing everything the exact same but I can't get it to connect the way it should. In real life all the hinges are attached perfectly and there is no stress. I am trying to get the whole angle section to look like this,

except with the bottom hinge hooked up to the 2x8 plate.

I have tried several different ways of putting it on but none have worked.

Does anybody have any ideas on how to get it to work?

Any help would be appreciated.

How do I get that?

I slammed the connection together at 45.67 degrees on my first attempt but then wasn't able to replicate it. It is difficult to connect a plate at both ends at a 45 degree angle since the hypotenuse = 1.414 times the side, and you can't achieve a length of 1.4 even with a jumper plate. If it is for a roof, I recommend the bottom remain unattached (e.g., Mill Village Raid).

Ok thanks, here is the file My link

That did it thanks so much!!! I just put 45.67 in for the angle measurement and it hooks right up. Thanks again.

Congratulation you did it! so this is for referance.

Method 1: Trail and error

Move out 1x1 plate with holder on top, then try to input angle until can move it back connected.

Easy way but can not get ideal angle.

Method 2: Windows's calculator (scientific view)

brick width:hight = 5:6

horizontal edge 5x7=35, vertical edge 6x6=36,

arctan(36/35)=45.806929455102374376995342349908 degree (paste from calculator)

hypotenuse= square root 35x35+36x36= 50.209560842532769557615444365317

(Not exactly 50=10 studs, This is why auto hinge align tools didn't work, it will not allow any collisin )

(click "Inv" button for arctan)

Here's an excel file I made that will give you all possible distances and angles. You can also enter the maximum tolerance you can accept without stressing the bricks too much. (TLG uses 0....or rather they are supposed to )

If you find any errors or enhancements, let me know

EDIT: Removed the file temporarily - updating it.

Very useful and clever use of excel!

One question, I try to use it to get same angle as my calculation but can not. Please advice.

@ bbqqq: You want 45.67 degrees in the bottom angle to match your real-world Lego triangle. The "right triangle" must then have the opposite (upper) angle be (90-45.67) degrees = 44.33 degrees.

I tried inserting a new column in Superkalle's Excel spreadsheet and copied the imbedded formulas from the other nearby cells, but I'm confused....

I used 45.80692945 degree on LDD then it looks good.

Not sure but seem like have to add full brick = 1.2 stud formula.

I made a small (well not so small ) error in the excel file. Fixing it now.

Seeing how well you answered my first question, I have another problem I need help with.

I am making a barracks/stable for the CCC IX, and I am making a model of it in LDD.

It is supposed to open right down the center, and it did for a long time. But since I started putting the roof on, it won't open anymore. I checked and made sure that there are no pieces hooking together the two sides except the hinges. I know this for a fact because if I take the hinges off and then use connected selection on one side I can move it away from the other side. As far as I can tell there is nothing in the way either.

So any help I can get would be wonderful.

Oops, you are right. Thanks a lot, I don't think I would have realized that for a long time.

I got 7 studs long and 2 plate's lower down.

Your model can use hinge align tool. Because it is a 3:4:5 triangle (didn't stress bricks at all).

Would you like me to try making a longer version?
