I need to realign a board dimension that I imported through a DXF file. It is not straight, can i realign it to be straight? Please see the attached image.

Hi

There is a manually way but you have to eyeball it level and its not

that simple. The following give you more control

As the shape needs to rotated, you first need to find out many degrees

to rotate it.

Click the 'Information' icon and then click on the straight line along

the bottom.

In the information box that appears you can read the angle of that line

which is likely to be about 355.55 degrees

Subtract this from 360 degrees and that's your rotation angle.

Rotation will be anticlockwise for positive numbers.

Next, turn off all layers except the dimension layer so you don't rotate

something else in error.

Click the Group icon an draw the rectangle around the shape.

Click the 'Rotate' icon  and observe in the toolbar the 'Angle' is 90

Type in your calculated angle and hit enter.

Then, apply the rotation to the group and it will rotate it to where you

need it.

Now it may not be exactly horizontal due to rounding errors in the

angle. Verify this by observing the information of that wire as you did

at the start.

Rishab,

What Warren writes will get you there.  However, there is an easier and

more exact method to accomplish this goal.

Right-click on the wire in question to bring up the context menu, then

select Properties.

If the line is not a straight line, then the Curve property will be

displayed.  Set it to 0 to straighten it out.

Since you're referring to a board dimension, you probably also want to

make sure that the line is either exactly vertical or exactly horizontal.

Near the top of the dialog box are From and To properties that represent

the start and end points of the line.  Each point is defined using

Cartesian coordinates with an X-value and a Y-value.  (The X and Y are

not labeled.)

If the line is to be horizontal, then set both of the Y-values of the to

the same value.

If the line is to be vertical, then set both of the X-values to the same

value.

Click "Ok" and you're done.

HTH,

    - Chuck

Chuck's method is flawed. It will make the bottom line level but the

rest of the object will not have been rotated so the object as a whole

is not the shape you started with.

There are other considerations as well.

The ends of the wire in question will likely not end at the same points

as the arcs so the board outline is not continuous which may cause it to

be rejected by the boardhouse.
