Allgemeine Struktur und Funktion
Profile können beliebig viele Sätze an Ziehpunkten haben. Unten wird eine Liste von Ziehpunkten für das standardmäßige Profil Normal angezeigt (UniversalCtrl.tcw).
...
- Verschieben nur entlang dieser Achse (X).
- (Cube) Scale bi-directionally BUT only along this axis Quader) Bidirektional skalieren, aber NUR entlang dieser Achse (X).
- (Rectangular cuboid) Scale uni-directionally on this side (equivalent to dragging one face of the selection bounding box).
- (Rectangular cuboid) Scale uni-directionally on this side (equivalent to dragging one face of the selection bounding box (opposite face from #4)).
- (Rectangular cuboid) Scale along both axes Rechteckiger Quader) In eine Richtung auf dieser Seite skalieren. Entspricht dem Ziehen einer Fläche des Begrenzungsrahmens der Auswahl.
- (Rechteckiger Quader) In eine Richtung auf dieser Seite skalieren. Entspricht dem Ziehen einer Fläche des Begrenzungsfelds der Auswahl (gegenüberliegende Fläche von Nr. 4).
- (Rechteckiger Quader) Entlang beider Achsen skalieren (X, Y).
- (Colored arc and cylinder) Drag, but only on these two axes Farbiger Bogen und Zylinder) Ziehen, aber nur entlang dieser beiden Achsen (X, Y).
- (Yellow sphere) the reference pointGelbe Kugel) Referenzpunkt.
- (Colored ball) Acts like the rotation handle for accurate snapping Farbige Kugel) Verhält sich wie der Drehziehpunkt für genauen Fang (Y).
- (Colored ball) Rotate around associated axis Farbige Kugel) Um verknüpfte Achse (X) drehen.
- (Colored ball) Rotate around associated axis Farbige Kugel) Um verknüpfte Achse (Z) drehen.
- (Colored arc) Rotate around associated axis.
- Boundary box

Snapping, accurate / non accurate handles
Handles that provide accurate transformation (with mouse snap) are marked with outlined callouts on the illustration (handles 7, 8).
For the handle to perform an accurate transformation, it is necessary to specify yes for the handle_snap_to_center variable in the profile. In this case the mouse cursor will be pulled up to the reference point or to the center of the visible part of this handle.
'handle_snap_to_center' variable
In reality, even if the above mentioned variable is not set, a handle can perform accurate transformations – for example, using the edit bars.
...
A user can assign priority to handles. If several handles with varying priority get into the cursor aperture, the handle with the higher priority will be chosen. The following priorities are set for the default profile: Reference Point has the highest priority (number 0), Boundary box – the lowest (-1).
Priority is controlled by the handle_priority variable:
'handle_priority'variable
Small handles
The ability to zoom in/out makes it reasonable to create handles of different sizes. A combination of large and small handles provides a way to fit interactive handles in the window tightly, without obstructing the view.
Seven handles at the spike of the X axis

The Normal profile includes the following portals:
Portals: movement along axes, movement in planes, rotation around axes.
