Generate Points Along Line¶
Use this dialog to set parameters for generating centroid, curve points, or profile points along a line or polygon.
Where can I find the dialog?¶
Right-click in the horizontal list field and select Tools - Generate Points Along Line..., or right-click on the screen and select Generate Points Along Line...
Point Number¶
The property for point number in Gemini Terrain is S_OBJID. This is created for all points according to the following naming convention:
<lineID>_<prefix>_<length>
Inherit Properties from Line¶
If you want to include the line's properties, you can check Inherit properties from line. This can be useful in many contexts, for example, to track the origin of the points.
Calculate Profile Interval in 3D¶
By checking this field, points are generated based on profile interval in 3D, instead of distance in the 2D plane.
Generate Centroid in Polygon¶
This option calculates the centroid in the polygon. The function works on all polygons that lie in a plane, both horizontal and inclined.
A typical example is finding the center point of a pile imported via IFC or DWG.

Generate Curve Points¶
If you check to generate curve points, only start point, bend point (line without rounding), curve point (line with rounding), and end point on the line are created.

Generate Points with Profile Interval¶
With this option, you must specify the profile interval, i.e., the distance in meters between the points to be generated.

Settings¶
Point ID Prefix¶
The program automatically assigns lineID/polygonID and length (from line start to generated point) as point number. Additionally, you can provide a prefix after lineID/polygonID.
Profile Number Offset¶
This field specifies the length value where the line should start.
Start Profile¶
Distance (meters) from line start to the first point/curve point.
By checking Interval relative from start, points will be generated with profile distance from the selected start profile, rather than from the start of the line/polygon itself.
End Profile¶
Distance (meters) from line start to the last point.
Offset¶
With this option, you can generate points with an offset normal to the centerline.
