Way to rotate a group of lines and keep their angles in relation to one another. (Building envelope) X-15

[someguy]

Hello new chief use here,

 

I am having trouble rotating a group of lines and keeping there angles in relation to another. I have a building envelope that has non perpendicular lines and I want to rotate them so one line is parallel to my house and I can know if it fits on the lot. It seems I can only do one line at a time and it loses the angles. my other program has an align command that I can easily use to accomplish this.

 

I get the subdivision cad files from the surveyor and I use them to fit the houses. Seems like a waste to have to use another program to do this then import them to Chief but if its the only way then so be it.

 

 

Thanks,

Rocky

A screenshot of the lines and what you want to do with them would help. You should be able to group select them the use the transform replicate to rotate them

If I am following along correctly you should have a polyline so if you select the whole thing you can then double click the Make Parallel/Perpendicular tool and it will bring up a dialogue that allows you to "Rotate the entire Polyline"  but then if you are using the north arrow you may need to use Jasons method to keep everything in sync by selecting the arrow as well and rotating all.

thanks for the replies, Here is what I am working with. I want to rotate all of this and make the line with the 80.22 a straight 90/180 in the program. Hope this makes sense

Very easy to do what you want

Have you looked up Make Parallel/Perpendicular in help?

If so, what is not working?

I assume you want them all rotated the same amount

 

sometime i will click on the line that I want to be at some angle, and click on transform replicate, click on rotate->absolute angle, and then record the angle it is currently at, and the subtract that from whatever angle you want it to be, and then group select all the lines, go back into transform replicate, and then rotate that "relative" amount..

 

so if that 80.22 line is at 285 deg and you want it at 270(vertical), then the difference is 15. so group select all the lines and rotate them relative -15 deg (negative is clockwise). they will all move -15 deg, and your 80.22 line will be vertical

Yeah seems like this would be the only way to do what I want. Seems odd a simple rotate command can’t use make parallel/ perpendicular if I select more than 1 object. Unless I’m using the command wrong. 
 

 

thanks for all the help.

the other way you can do it which is not as accurate is to group select them, then hold the control key down while you rotate the group with the mouse. I do this a lot for pictures of site plans. I draw a horizontal line then try and align the plot line in the picture to line up to the horizontal line i just drew. but even then I will typically still adjust in the Tranform replicate 0.1 deg one way or the other to get it close to perfect as I will then draw setback dimensions from it

There are probably several ways to do what you want.

I suspect that the Make Parallel tool may not be the most appropriate one in this case.

Try this one using a dimension.

Draw an Angular Dimension so that it results in an angle between a vertical reference line and the controlling side of your polyline.

Group select the objects you want to rotate.

Click on the angular dimension text and a Set Angular Dimension dbx will open.

Enter zero.

All your objects will rotate the desired amount.

 

 

 

 

 

 

Or...even simpler, you can set the Additional Angles to the rotation angle you want, group select the objects, and use the rotation grip to rotate all the objects to the Angle Snaps value.
