Electronic protractor

Is there any way to make a protractor so when the user drags the tip of the line it will display the angle of the line in a text field?

Hi Maxs,

Of course, there are ways to do this. Where do you get stuck?

I suggest you check out the newImage and newGraphic messages, if you want the angle to be visible when creating a new line using Rev's line tool. If you want something else, I propose you tell us what you are trying to do exactly and then the readers of this forum can try to help.

Best,

Mark

Thanks, Mark,

Rule number 1- Be clear and concise.

I would like to show students how to find angles on a protractor. I have a graphic of a protractor, and I overlayed a graphic of an arrow. How nice it would be if the user can drag the tip of the arrow over the part of the protractor, and a text field would identify the degree of the angle.

Well, I did notice that the angle function can return the angle of polygons, so I was thinking that there may be an easy way do it.

So if anyone can help, feel free to display any intellctual superiority. Thanks, Max

that sounds like, you'll make also other software you could use the ae. i use it very often. you could also code it yourself, but it is not that easy, i also tried it and gave up.

to come back to the ae: there are two funktions called findangle() and pointoncircle() so you could easy draw a line and display the angle.

That's it. I just purchased Arcade engine. I think that will do the trick. Max
