Is there any way of making angles 360 degrees?

Anonymous — Thu, 18 Jun 2020 06:31:18 GMT

Hi,

I am struggling with making angles 360 degrees as it keeps changing direction and doing degrees up to 180.

This makes it very difficult and tedious when I have to change all of the information I have in a 360 anticlockwise rotation to 180 degrees in the opposit direction.

Have any of you guys got any suggestions?

Thanks

In the Sketch environment I don't know a way to store Angular dimensions greater than 180.

Silly workaround, but perhaps it helps:

Draw a "pacman":

Add an "arc length" dimension:

And use the following formula:

Does that help?

Hi! The confusion here is that the parameter value and dimension display are different. Geometrically, they represent the same thing. The actual parameter value can be any angular value except negative value. The display value is based on the closest angle between 0 and 180.

Many thanks!

If the end goal is to have a table on your drawing with the tank nozzle radius and angle updated automatically then I would also be interested since I think we do ours manualy.

Does the parameter still say 270deg and it's just the dim showing 90deg?

Hi Guys,

I believe yes, it is true the parameter value can go beyond 180 but the display value will never go as such. This inconsistency is to cater to documentation need. In drawing, an angle is rarely over 180 because it an introduce ambiguity. An angle in a drawing view is always less than 180.

Many thanks!

Really?

In the Sketch environment it is true, you will never see angles (dim values) greater than 180. But in a drawing you can do this: >>Angle_Dimension<<. (Irrespective of whether this is useful or appropriate)

Hi Jürgen,

Many thanks for sharing the workflow! Yes, drawing does allow the complement angles. But, if you retrieve dimensions from a sketch or a feature, the angular value should always be less than 180. I think it is to avoid confusion, since it can be interpreted in different ways.

Thanks again!

Angles display 0-180 degrees. I need to be able to show and use 0-360 degrees. there is no ambiguity about an angle being 213 degrees. however if i measure something as 21 degrees, that can be EITHER side of 0 degrees. This is the way draftsmen think. I want to use a 360 degree azimuth. this is how a compass displays. It is how survey instruments display. How can I change to that?

Hi! As the prior discussion pointed out already, there is no way to specify angle larger than 180 in a 2D sketch. It is a limitation for now. Another workaround to consider is to create an angled workplane (before the sketch). This workplane should be perpendicular to the sketch plane but rotates around an axis penetrating the sketch. The workplane can rotate from 0 to 360 freely. Then project the workplane to the sketch. Use the angular parameter to drive the workplane instead of an angular dimension.

Many thanks!
