SANJIESAN CREATOR / Vector stroke design
Check a vector stroke’s corners at the small size
A narrow turn in a stroked path can create a pointed extension that becomes more noticeable than the intended icon. Illustrator’s stroke reference distinguishes cap styles, join styles and a miter limit. Use a simple original outlined object to inspect the corner, instead of changing the whole drawing’s stroke weight to hide one local problem.
Locate the actual source of the spike
Inspect a small original symbol with one acute turn. Compare its path centreline with the rendered stroke. Determine whether the extra point comes from the intended geometry or from the stroke join. Keep the path unchanged for the first comparison. If the underlying shape itself is wrong, a rounded join may disguise it but will not explain the object. Separate that drawing decision from the appearance setting.
Compare the relevant join choices
On working copies, compare the documented pointed, rounded and bevelled join behaviours at the same stroke weight. Inspect whether the corner still matches the object’s character. Do not select a round join simply because it removes the spike if the intended object requires a clear sharp edge. When the pointed treatment is appropriate, inspect the relevant limit and actual output rather than using a guessed universal number.
Check ends, gaps and the family view
Return to the smallest intended size. Inspect open ends, narrow gaps and nearby strokes as well as the repaired corner. Place the object beside related symbols if it belongs to a set. A local fix that makes one icon look much softer than its neighbours may need a broader style decision. Keep the selected cap and join behaviour documented with the artwork so later exports can be compared against an understandable reference.
