How to make a vase, cup or curved part with sections

Step by step

1. Draw the base shape

   A circle, a polygon, a star or any outline drawn with the pen. Set the height in Properties.

2. Open the node editor in 3D

   Select the part, press N and switch to the 3D view. Blue lines link each bottom node to its top node.

3. Double-click a blue line

   A section (ring of light-blue nodes) appears at that height. The shape does not change yet.

4. Shape it

   In Properties, change the section Width (150% = belly, 70% = waist) and Height, or drag a single node. The black arrow and the X/Y/Z box move it precisely.

5. Straight or curved sides

   Choose "Curved" for a smooth wall that passes through every section, or "Straight" for facets.

6. Hollow it and print

   Use Wall in Properties to make it hollow (a cup or a pot), or print it solid in vase mode in your slicer.

Tips

• Up to 12 sections per part.
• Overhangs above 45° need support: keep bulges gentle or check them with the Print X-ray.
