Shell – Edit extrusion vector of extruded shells

ArchiCAD 15 New Features – Shells Edit extrusion vector of extruded shells A host of editing commands are available for Shells. For Extruded Shells, there are commands available for both the Extrusion Vector and the Profile Polygon. There are three…

Shell – Edit rotation axis of rotated shells

ArchiCAD 15 New Features – Shells Edit rotation axis of rotated shells There are two editing commands are available for the Revolution Axis of Revolved Shells. If we click the starting point of the Revolution Axis these commands are not available on the…

Shell – Drag profile/drag extrusion vector

ArchiCAD 15 New Features – Shells Drag profile/drag extrusion vector In case of Extruded Shells we can change the position of the Extrusion Vector and the Profile Polygon relative to each other. If we click on an edge of the Profile Polygon and choose the…

Shell – Rotate/Mirror profile of shell

ArchiCAD 15 New Features – Shells Rotate/Mirror profile of shell Another pair of Pet Palette commands available for Shells are the Rotate Profile command, which will rotate the Profile Polygon in its own plane… and the Mirror Profile command, which will…

Shells – Manipulate extruded shells

ArchiCAD 15 New Features – Shells Manipulate extruded shells When Shells are created, their orientation may not always be what you need. This can be changed however. To illustrate this, let us consider the following two Shells. We wish to connect them…

Shell – Ruled shells operations

ArchiCAD 15 New Features – Shells Ruled shells operations There are three Pet Palette commands that are specific to Ruled Shells and are related to either Profile Polygon of the Ruled Shell. The first is called Elevate Profile. It works the same way as…

Shells – Free rotate shells in 3D

ArchiCAD 15 New Features – Shells Free rotate shell in 3D The usual move-type commands: Drag, Elevate, Rotate, Mirror and Multiply, are available for Shells and the work exactly the same as they do in case of other element types. Another available command…

Shells – Define contour polygon for shell
