24 **Cone property panel**
26 The property panel contains an image which explains the meaning of input values:
28 - **rmin1, rmax1** - minimal and maximal radii of the cone base.
29 - **rmin2, rmax2** - minimal and maximal radii of the cone top.
30 - **z** - height of the cone.
31 - **startphi** - angle from the axis to the start of the cone segment.
32 - **deltaphi** - arc angle of the cone segment.
34 **TUI Command**: *model.addConeSegment(Part_doc, rmin1, rmax1, rmin2, rmax2, z, startphi, deltaphi)*
36 **Arguments**: Part + Rmin of base + Rmax of base + Rmin of top + Rmax of top + height + start angle + arc angle.
41 The Result of the operation will be a SOLID.
