Polygon

When basic geometric primitives cannot meet the needs of complex architectural outlines, irregular bases, or custom part designs, you can use the Pen Tool to freely draw a polygon and convert it into a 3D solid model with thickness and bevel effects in a single step.

Custom polygons combine the flexibility of 2D drawing with the precision of parametric modeling. Through simple point-and-click operations, you can create any closed shape, ranging from simple triangles to complex industrial contours.

How to Draw a Polygon?

1

STEP 1

In the top navigation bar of the canvas, click the Pen Tool icon. The mouse cursor will change to a pen icon, indicating that you have entered drawing mode.

2

STEP 2

Click the left mouse button anywhere on the canvas to place an anchor point. iCraft will automatically connect adjacent anchor points with lines to outline the shape.

3

STEP 3

Move the cursor back to the first anchor point and click it to close the path.

4

STEP 4

Press ENTER, the editor will automatically fill the surface and convert the shape into a polygon, which can then be edited like other scene elements.

💡Tips:

• It is recommended to draw polygons in 2D view (shortcut V) for a more intuitive experience.
• Enable Grid Snapping (shortcut G). The cursor will automatically snap to grid lines and anchor points, helping you place points more precisely.
• If you place an anchor point incorrectly, press Ctrl + Z to undo the previous point.
• Press ESC to clear all anchor points and exit drawing mode.

Polygon Special Parameters

• Height Controls the extrusion depth (thickness) of the polygon. The larger the value, the thicker the resulting model.

  Default value: 0

  Adjustable range: 0 ~ unlimited
• Radius Applies rounded edges to the polygon or the extruded polyhedron. The value represents the arc radius used to smooth the edges. Larger values create smoother edges. A value of 0 produces a standard polygon or polyhedron. Default value: 0

  Adjustable range: 0 ~ 10
• Subdivision Controls the mesh density of rounded corners and curved parts of the polygon or extruded polyhedron. Higher values produce smoother edges.

  Default value: 8

  Adjustable range: 1 ~ 32
• Bevel Adds a smooth bevel to the top and bottom edges of the polygon or extruded polyhedron, improving visual appearance and light reflection. Default value: 0

  Adjustable range: 0 ~ 1
• Bevel Sides Effective only when Bevel is enabled. Determines the smoothness of the bevel surface. Higher values produce rounder edges. Default value: 3

  Adjustable range: 1 ~ 10
• Stroke A toggle switch that determines whether the polygon or extruded polyhedron displays surface outlines. Default: Disabled
• Stroke Color Selects the color of the stroke using the color picker.
• Border Line Width Adjusts the thickness of the stroke. Default value: 0.03

  Adjustable range: 0 ~ 0.1
