SPoints (Survey Points)

SPoint is a word derived from Survey Point. An SPoint is a cell with a name and a height that can be displayed with the point. SPoints can be configured to your requirements. You can (for example) decide exactly what a spot shot or station point should look like.

An important feature of SPoints is the positioning of the point relative to the height. uSMART does not use the decimal point position of the height as an indication of where the point is. As most CAD mapping users will know, this produces inconsistencies in the visual appearance and the positioning of detail. With uSMART, the position of the placed point (cell) remains the actual point both for visual and for snapping purposes and the text height is positioned around this point, omitting the plotting of the actual decimal point. This feature can however be overridden if an X and/or Y offset for the height is specified. In this situation the height is written as a single text item (with its decimal point) even though the "snap" point remains at the position of the original point placed (cell).

SPoints are used extensively in uSMART. SPoints form the basis of routines such as TIN creation, thematic displays, contour generation and design routines.

SPoints can easily be added to selection sets i.e. if a selection set is active when the "Place" button is pressed, SPoints will automatically be placed on the vertices of this selection set. This can therefore also be effectively used to "convert" a simple MicroStation point to an SPoint.

Existing SPoints can be manipulated and regenerated, thereby effectively enabling the following changes to be made to them:

These are just a few of the many ways in which SPoints can be utilised.
