Description
Inserts vertices (string points) in the selected string.
This command is influenced by the state of the edit-coincident-points-switch . If this is turned on then the point is inserted on any coincident segment. (Currently a coincident segment is defined by having coincident vertices).
This command is also influenced by parameters that have been defined for your project. In the Design window, editing will always be made by honoring the current orthogonal view. In the 3D window, however, there are 3 possible ways that editing can be performed:
-
Data can be edited relative to the screen (that is, around a plane that is orthogonal to the current camera view) - this is very similar to the behaviour of the legacy Design window. This behaviour is performed if the project setting Move relative to screen is enabled.
-
Data can be edited relative to the current data plane. This "3D" editing allows the planar alignment of data to be maintained regardless of the position and direction of the 3D 'camera'. Note how the bounding box aligns with the plane of rotation/point movement. This behaviour is performed if the project setting Move relative to plane is enabled.
-
Data can be edited using alockedview. This is the closest analogy the3Dwindow has to the legacy Design window in that the camera will always be orthogonal to the view section, even if that section position is modified in another (freeform)3Dview. Find out more about section locking...
You can review and adjust your settings for editing by accessing Home ribbon | Project | Settings | Points and Strings and selecting either the Move relative to plane or Move relative to screen options, found within the String/Point Movement command group.

Whilst digitizing, you can complete the digitizing operation by double-clicking or double-tapping the final point position. |
If you are using a 3-button mouse, the middle button (or the button that emulates this function) will not perform any function in relation to this command.
|
|
This command honors both left-click and right-click mouse selection actions i.e. without snapping and with snapping, respectively. Snapping uses the currently defined snap settings (Homeribbon |Snapping | Settings). Snapping provides additional control when selecting the start and end points on the selected string. The left-click mouse action will select a point on the string which is closest to the cursor. |
How to use
|
This command can be run either before or after selecting the required string. The steps below show how to use the command in the case where the string has been preselected. For increased control, first select the required string before running the command. Inserting points without preselecting the string can potentially result in points being inserted in adjacent strings. Theundo-last-string-editor delete-points-mode commandscan be used to remove incorrectly inserted points.When inserting string points, any filters or display options are honored. |
- Select the required string.
- Run the command.
- Follow the prompts displayed in the left side of the Status Bar.
- Click, click-and-drag or right-click to place the new point.
- Repeat step 4 for any additional point(s).
- Click Cancel.
The Different Click Options
The following mouse click actions can be used when inserting points:
-
Left-click - inserts a new vertex, between the two closest vertices, at the selected location.
-
Right-click - inserts a new vertex, between the two closest vertices, at the snap point.
-
Left-click-and-drag - inserts a new vertex in the string, between the two closest vertices, at the location where the click-and-drag action finishes.
-
Right-click-and-drag - inserts a new vertex in the string, between the two closest vertices, at the final snap point.
The last two methods are essentially an 'insert and move point' action all in one.
Point Depth Interpolation
Inserting points in a 2D graphical environment (computer screen) when working in 3D space, requires the interpolation of a third dimension. The position of the point is calculated as a mean interpolation of neighbouring screen points, e.g.
For example, suppose the Design window's view plane is horizontal at an elevation of zero. Suppose also there is a string with each of its Z coordinates at 10. If a point is inserted then its Z coordinate will be added at an elevation of 10.

The middle mouse-button activity is reliant on the correct system mouse settings being set for your operating system/hardware combination. For more information on configuring your middle-mouse button, consult your operating system or hardware's supporting documentation, as these settings are proliferated to system usage. |
