Shape a vase by its profile, not by a pile of sliders.
Vas draws the silhouette and you edit it directly. Choose a cross-section, set the wall and floor thickness, then stack reversible changes — twist, taper, ribs — in the order you want them. Millimeters stay authoritative the whole way to the export.
1 · Start from a form
A vase, planter or bowl to edit, not a blank CAD document
2 · Shape the profile
Drag the silhouette, pick a cross-section, order the changes
3 · Export
Wall thickness and printer fit checked, then an STL or 3MF
