How to create and shorten arcs
I have a couple of problems with arcs in AS 8 Pro.
1) To create an arc I first draw a circle with Draw Shape, then I split it into more points using the menu Scripts -> Draw -> Split curve, then I try to delete the points outside the arc that I want to create. Unfortunately this doesn’t work because the 2 end points of the arc are always linked, thus altering the arc itself. So I guess this is not the proper way to create an arc. Could you please suggest the right way.
2) After created an arc (by drawing it over a circle as I said before) I just want to shorten it from a frame to another, e.g. from this initial arc:
after a while I want it to become like this:
and after another while like this:
... until it completely disappears.
I could not find an easy way to do so. It seems that it is not possible to dynamically cut off the points from a frame to another. So I tried to move the points (collapsing them) but this doesn't works too.
Any help will be greatly appreciated, thanks in advance.

Re: How to create and shorten arcs
Stroke exposure or masking are probably what you want. Hide edge and line width might be useful there too.
Re: How to create and shorten arcs
Something like this?
If so, just make a circle shape with no fill and at frame 0 use stroke exposure and drag the mouse to the left, at frame 1 copy frame 0 at any spot in the time line drag the mouse to the right to any spot on the circle.

Thanks 2ner and sbtamu for your help.
Unfortunately I'm just a beginner, so would you be so kind to tell me where I find the "Stroke exposure" or "Masking" option in AS 8?
Thanks again.

Re: How to create and shorten arcs
Hi sbtamu, it's me again.
Yes your animated GIF is exactly what I need. So, while we are on this subject, could you please suggest the easiest way to create an animated GIF from a AS 8 project?
I'm asking this because I noticed that AS does not directly export this format, am I right?
Thanks in advance.

Re: How to create and shorten arcs
Are using pro or debut?
I exported it from AS as jpg sequence and use my photo editor to make an animated gif from it.

Thank you sbtamu,
I'm using Pro, I'll tray what you suggested.
Could you please also tell me where can I find the "Stroke exposure" or "Masking" options?
Thanks a lot for your patience and help.

Re: How to create and shorten arcs
The exposure tool is on the tool palette and you can see an example of it in the tutorials in the help section. Masking is done in the layer properties by double clicking on the layer and going to the mask tab.
Re: How to create and shorten arcs
Thanks sbtamu, but I don't find any exposure tool in my AS 8 Pro toolbar:
Also, I don't find the Mask tab in the layer properties:
Do I need another AS version?
Thanks again.

Re: How to create and shorten arcs
forgive the barge-in ...
stroke exposure is there in the Fill group - it's the the tool far right in the middle line ... lloks like a "bold" U with an faint upside down U attached...
masking: you need a parent layer (e.g. bone or group) that has masking enabled; then you'll see the masking tab in the child (vector) layers.
