Auto - snapping
This function is enabled by default. When enabled, the object moved close to the edge, center point, or grid line of another object will automatically align with these reference points, and blue lines will appear at the snapping positions.
Precise vector path selection
This function is disabled by default.
When this function is disabled, you can select a vector path by clicking on the selection box of it. The selections boxes of multiple vector paths, however, may overlap, causing difficulty in selecting the target vector path.
As shown in the following figure, it is difficult to select the purple line because it is located within the selection box of another line.
When this function is enabled, no selection box is provided for vector paths. You need to move the mouse pointer close to a line to select it. In this way, you can select a vector path without selection box interfering.
As shown in the following figure, you can select a line by moving the mouse pointer close to it and then clicking.
