To create a 3D profile based on a 2D hatch or text, use the following options of the command main automenu:
<H> Select Hatch
<A> Select Text
The normal flow of the 3D profile creation based on a hatch or text consists of the following steps:
1. Selecting a hatch or text (in the 2D window or on the active workplane). This simultaneously defines the workplane or worksurface to which the selected element belongs by default. (The hatch or text belongs to a workplane if it is located within the bounds of the workplane in the 2D window or at a position nearest to the boundaries of this plane.) The hatch and the workplane (surface) are marked as selected in the 2D window. Meanwhile, the preview image of the profile being created appears in the 3D view window.
To alter the workplane selection, use the option:
<W> Select Other Workplane
This will result in selecting another workplane or worksurface. Subsequent use of this option allows looping through all workplanes present in the active page. Meanwhile, one can watch how the profile being created adjusts dynamically in the 3D window.
When using a 2D element lying on the workplane, profile creation completes at this point. In the case of a flat profile, one can additionally:
2. Select a 3D node to snap the contour plane to:
<M> Select 3D Node for fixing Profile plane
3. Select a 2D node on the contour to snap the specified 3D node to:
<N> Select Node to be moved to 3D Node
To complete the 3D profile creation, use the automenu option or the respective button in the property window.
To undo the snapping to the nodes, use the following automenu options:
<K> Break link with 3D Node
<F> Break link with Node
Those undo the respective actions of repositioning the contour.
