The point feature class TB_PROFILE stores the created profiles. All profile features are related to this table.
When you create a profile in AutoCAD Map 3D toolset, you are prompted to position the profile in the drawing, which means that you can digitize the origin in the global coordinate system. This origin is stored in TB_PROFILE.
All profile features are defined in a local coordinate system, with the origin of the profile as point 0/0. The width and height of the profile depend on the profile length and height difference in combination with Z_ORIGIN, SCALE_FACTOR_HEIGHT, SCALE_FACTOR_LENGTH.

TB_PROFILE attribute |
Description |
|---|---|
|
FID |
Primary key. |
|
GEOM |
Origin of the profile in the global coordinate system. This is the local 0,0 coordinate. |
|
ORIENTATION |
Orientation of the profile. |
|
QUALITY |
Quality of the point. |
|
Z |
Height of the point. A standard point attribute. |
|
USER_ID |
User who creates the profile. Corresponds to MAPSYS.TB_USER.ID |
|
PROFILE_TITLE |
Title of the profile. |
|
PROFILE_DEFINITION_ID |
Profile definition used to create this profile. Related to TB_PROFILE_DEFINITION.ID |
|
Note: The values for the following attributes are set when you create a profile. If you change a PROFILE_DEFINITION_ID, the default values of the definition are set.
|
|
|
SCALE_FACTOR_HEIGHT |
Scale factor for the height, used to define the relationship between the global coordinate system and the profile coordinate system for the height information. NORTHING_PROFILE = (Z - Z_ORIGIN) / SCALE_FACTOR_HEIGHT + GEOM.NORTHING |
|
SCALE_FACTOR_LENGTH |
Scale factor for the length, used to define the relationship between the global coordinate system and the profile coordinate system for the length information EASTING_PROFILE =(LENGTH_GLOBAL - DISTANCE_ORIGIN) / SCALE_FACTOR_LENGTH +GEOM.EASTING |
|
Z_ORIGIN |
Specifies the origin of the profile. Reference altitude of the profile. You can enter this value in the Profile Manager dialog box. |
|
DISTANCE_ORIGIN |
Specifies the reference distance of the profile. The origin of the profile is at this distance. |
