Keep a circle's shape when opening a small piece

Post by rogermate »

This is a real basic vector drawing question. I've read on this forum that AS uses a different mathematical approach to storing curves. Circles are easy with AS. But how do we take a circle, and then but a small opening on one side of it?

It only takes 4 points to describe a circle. My attempt was to add points on either side of the spot where I want to open the circle up, hoping to remove the edge between the two extra points. But every time I add a point, the curve of the circle gets really messed up. Is there a way to lock the initial position of a curve?

I guess another approach would be using more points with the freehand tool.

Why don't just simply hide one edge?

In AS5.6 you can create your circle, select all the points and then scripts/draw/split curve.
Might give you what you want.

I want to fill the circle, but with a missing "pie slice".

I ended using masking to get it done quickly, and eliminated the shape
with "subtract from mask".

Not need to mask for that case:

That's exactly it. I had this feeling that there had to be any easier way of doing it. Previously was using cut out images, just now really learning the drawing tools. And when I said "easy way" it really meant "keeping myself busy with work the hard way, but still moving forward".

OK, burn this into the nueral network:

Create simple shapes
Run the split curve script to presserve shape but add points
Combine / merge shapes


The silver lining to what would be an embarrasing moment is that working the "hard way" is not a loss as i've still learned while using
the manual draw tools, and am even stronger now with masking.

Thanks again Genete.
