Curve offset operations

A system comprising:

• a processing device;
• and
• a computer-readable storage media storing instruction that, responsive to execution by the processing device, causes the processing device to perform operations including:
• receiving a set of input points via a user interface, the set of input points drawn as a freeform line;
• selecting an offset value from a plurality of candidate offset values, the plurality of candidate offset values detected based at least in part on respective distances within the user interface between the set of input points relative to a portion of an object;
• generating a segment based on the offset value as a trajectory defined by the set of input points as offset from the portion of the object;
• and
• presenting the segment for display in the user interface.

One-or-more non-transitory computer-readable storage media storing instructions that, responsive to execution by a processing device, cause the processing device to perform operations including:

• receiving a set of input points via a user interface, the set of input points drawn as a freeform line;
• selecting an offset value from a plurality of candidate offset values, the plurality of candidate offset values detected based at least in part on respective distances within the user interface between the set of input points relative to a portion of an object;
• generating a segment based on the offset value as a trajectory defined by the set of input points as offset from the portion of the object;
• and
• presenting the segment for display in the user interface.
