Circumference dimension

[Anonymous]

Hi,

I need to measure circumferences of spline.

Does some one new how to dimension circumference?

I can dimension between 2 points but I can not dimension the circumference

Thank you

If all you want to do is measure the curve length, the Measure command will tell you this:

Hi,

Thank you for your answer.

Is there an option so I can fix the circumference .

For example if I look to the measure it is 181mm but I want 188mm.

Unfortunately, no, today, there is no way to constrain a spline's length today.  Please add this to the Fusion 360 ideastation.  I did not see a request like this there, yet.

While there is no way to constrain the spline, its length can be changed with dimensions/parameters:

Fix/Unfix the interior point.  Changing either of the dimensions will change the length of the spline.  It will also change the shape of the spline.

If you need the relative positions of the spline points to remain the same, then use the offset command to create a new spline with the desired length. 

Both methods are trial and error, but it should not be too hard to get within a few nanometers of the desired length
