Draw three simplified map symbols that communicate soil erosion severity — low, moderate, high — as distinct, single-color vector shapes sized to 12 px, 18 px, and 24 px respectively; use pen and shape-builder, deliver as one artboard.

Before I hand these to field crews, make the symbols instantly readable at a glance — increase contrast between severity levels, use a clear progression of form (dot → dashed line → gullied patch), test legibility at 12 px on a printed clipboard photo, and export as a single-layer SVG and 72 dpi PNG.
when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

How to do it

The tool
Pen Tool

The Pen tool creates precise lines and curves to form shapes and paths in Adobe Illustrator.

  1. 1

    Open Illustrator.

  2. 2

    Select the Pen tool or press P.

  3. 3

    In the Properties panel, set the stroke weight to 1 pt.

  4. 4

    Set the stroke color to black in the Properties panel.

  5. 5

    Set the fill to none in the Properties panel.

  6. 6

    Click anywhere on the artboard to set the first anchor point.

  7. 7

    Move the pointer and click again to create a straight line segment.

    Best practiceFor curves, click, hold, and drag to where you want to go next. The Pen tool acts like a French curve device.

  8. 8

    Continue clicking to add more anchor points and draw your desired path.

  9. 9

    To close a path, click on the first anchor point you created.

  10. 10

    Save your work by going to File > Save or File > Save As.

Use the Add Anchor Point Tool (+), Delete Anchor Point Tool (-), or Convert Anchor Point Tool (Shift-C) to refine your paths.

Illustrator's scripting capabilities can automate path creation or modification, but complex Pen tool operations typically require manual input.

Questions people ask

honest answers

Because you rarely think 'I want the redaction tool'. You think 'I have to share this without leaking the client's details'. Start from the need, and the feature finds you.

Real. Every job here was drawn from what people in real roles were actually seen doing in Illustrator — not a feature checklist.

No. Each page gives you a ready prompt you can paste into an AI assistant, plus the plain steps to do it yourself. Start with either — the goal is the finished job, not the tool.
