Point Editor
Previous pageReturn to chapter overviewNext page

Purpose: The Point Editor is a tool that visualizes and modifies the point description of an entity.
Point Editor View of the Entity List: Before doing a point editing operation please switch to the point editing mode (use the Object Toolbar, button clip0064 ). Then select one or more objects in the same way as described in View 2D → Selection. If more than one object is selected the objects must be grouped (use Edit → Group) to perform point editing. One can also perform these two steps the other way around.

After selecting objects in point editing mode the Entity List will switch to the Point Editor View as shown in the screenshot below.

Figure 188: Point Editor View

 

The Point Editor View shows all points of the selected objects in a single list.

All the points which belong to one PolyLine are connected by a blue line in that list.

The red dots mark single points and the 2D/3D coordinates of a point are displayed next to the red dot. The coordinates are 3D only with Optic3D.

The caption of the Point Editor View displays the number of points.

Context Menu: To modify the points in the list or the list itself the context menu provides five operations. They are described next to the screenshot below. Select one or more items from the list by mouse click while keeping the Ctrl pressed. After the selection keep the Ctrl pressed and click the right mouse button. Then the context menu will be displayed. The points of the selected objects are marked in the View 2D by black dots. Clicking with the right mouse button on such a black dot will display the context menu too.

Redo: Redo the last Undo.

Insert: Inserts a new point in between the two adjacent points.

Point Editing with the Edit Items dialog: To edit one or more points use the Edit Items dialog shown below. One can get this dialog via the context menu (described above) or by double clicking on a point item in the list.

X,Y,Z: Edit these values to change the coordinates of a single point. Remark: Z coordinate is only available with Optic3D.

note

The Z-Coordinate is only available with the Optic3D Option.

Radio buttons: There are two update modes for updating point coordinates which can be switched by the radio buttons. Abs is the default mode.

Abs mode: The point coordinates are updated by a substitution of the old coordinates by the new ones.

Rel mode: The point coordinates are updated by adding the new values to the actual coordinates.

To All: These buttons are only active if more than one point is selected. To update the X coordinates of all selected points change the value of the X field and click the To All button next to it. Updating of the Y or Z coordinate for all points is done analogously.

Examples: To project all selected points on the plane Z = 1 select update mode Abs, change the value in the  Z field to 1 and click the ToAll - Button next to the Z field. To move all selected points in Y direction by 3 units select update mode Rel, change the value in the Y field to 3 and click the ToAll - Button next to Y input field.
