Direct User
Access
Direct User Access means the functionality available to end user of a
compiled application without any programming on part of the application
developer.
In this version Direct User Access is available for some mesh manipulation
operations and measurements
Direct User Access functionality is available via Advanced > Edit options in
context menu of the component (right mouse click). or click into window or the
component and press keys specified below. When selection is made the component
enters a special mode in which normal viewing rotation/zoom/pan manipulations
are disabled. Info line at the bottom of the component displays the current mode
and available options. The component automatically returns to the normal viewing
mode after completion of the operation. Pressing e key normally cancels
the operation and returns to the previous mode.
A Direct User Access mode often has a sub mode. For example to select multiple
simplexes on surface of a meshed object use s key to enter selection mode
and then press 2 key to enter Simplexes sub mode.

Selection
To select a number of items on the screen for further manipulation make sure the
component window has focus by clicking into it and press s key. Click and
drag mouse to define the selection rectangle. All items intersecting the
rectangle will be selected and highlighted with a different color. By default
vertices of a meshed surface are selected. Press 2 or 3 key immediately after s
to select simplexes or objects instead.
Pressing the Delete key with a number of objects (sections) selected
removes them from the model
The list of selected items can be obtained by the
application. See details in Selection Event.
To delete
Simplexes:
Select simplexes ( Click into window, s, 2,
select a rectangle ) as described above in Multiple Selection paragraph and
press the Delete key.
To modify vertices
In context menu (right mouse click) select Advanced > Edit > Select > Vertices.
Click and drag the mouse to select a rectangle on the screen. Vertices inside
the rectangle will be highlighted with a blue color. Rotate the scene if needed
to determine plane in which vertices are to be moved. In context menu select
Advanced > Edit > Modify. Hold the shift key and drag
the verticies with the mouse (left button down). The verticies will be
translated in plane parrallel to the plane of view.
It is recommended to use this operation only for minor modifications as the
meshed surface can quickly become invalid and will not be lighted correctly
To modify a vertex of a MeshSection object in
3D Debugger on the 3D Propertes page of the form select Render Type > Mesh
select Editr Mode > Modify and Modify Item Type > Surface. Hold Shift key, click
on a vertex and drag it. The vertex will be translated in viewing plane. Rotate
the scene to move the vertex in a different direction.
