  • Understanding Position and anchor points ONCE AND FOR ALL

    Posted by Tomer Katzir on February 6, 2022 at 10:01 am

    So, when i create a shape – there are a few position and anchor point properties:

    1. Path transform properties

    2. Shape transform properties

    3. Layer transform properties.

    My difficulty is in understanding what the numbers relate to. I understand that the LAYER position property for example – is the distance between the layer’s main anchor point to the 0,0 point of the comp.

    But i would love to know how where others get their values from so i can better understand how to better link these properties into other things + create shape layers in a better/ cleaner way.

    Really appreciate the help!

    Hey Tomer, its indeed a bit of dark-side and most often than not we just use them without much thinking about the reasoning. But in general – its micro to macro transformations, affecting different “level” of things. Anchor point basically is a position on a layer thats used as a base for all transform props.

    3. Layer transform properties and values are based on the layers placement within the composition. You change the comp size and they both updates.

    2. Shape transform properties works in the same way as layer transformations, JUST within layer space. Meaning, its a “deeper” level, where it affects only that object in a layer, and not whole layer itself.

    1. For path transform properties, I might be wrong here, but it just another depth of fine-tuning, which does not affect none of the above.

    To wrap it up – create a layer, try changing values and you will see how this exactly works.
