Information on points

The GROMA system allows the storage of the information on points directly to the drawing. This information is stored using the so called User Data Linkage in special PointString elements. This information can be used for some other functions:

Dynamic display of the point numbers

The numbers, heights and point codes stored in these items can be dynamically displayed on the screen. If this displaying is switched on, a number for each point is displayed according to the setting; eventually height and code are also displayed. This information is not a part of the drawing; therefore it will automatically disappear after deleting the point. When the point moves, the information automatically moves with it. In addition, these descriptions have a constant size all the time which doesn't change when enlarging or diminishing.

Coordinate list statement

Based on this information, a text coordinate list can be generated at any time with the original point numbers and updated coordinates overtaken from the drawing. Also the original point heights are maintained, even in 2D drawings.

Generating descriptions

When importing from the coordinate list, it is often convenient to create only the items type PointString with information on points in the drawing. When the drawing is done, you can batch generate descriptions according to the set attributes.
