File > Open Construction Lines

Loads construction lines from a file.

Construction lines are used to define detailed locations of underground features such as excavations, contacts structure etc. A Map3D model is normally built on top of this construction line data.

You will be prompted to search for a construction line file name, location and file format. Construction lines can be loaded from several file types:

•Point file format is a universal ASCII data file with the extension ".PNT". This format is useful for exchanging raw construction line data with other CAD software.

• AutoCAD-DXF format is a popular drawing exchange file with the extension ".DXF". This format is useful for exchanging construction line data with other CAD software.

The construction line data being loaded can either overwrite or be merged with existing data. The overwrite/merge option

File > Open > Merge Geometires

appears at the bottom of the open file dialogue box.

Merging multiple files into one database

You may select multiple files simultaneously by holding the standard windows "shift" or "ctrl" keys for multiple selections.

These files will be merging into one database.

This allows you to keep separate parts of construction line data in different files then easily merge them together into one database.

Another way of merging multiple files is to select the "Merge Geometries" option prior to selecting the additional file you want to add to the existing database.

This is useful if you already have construction line data open and want to add additional construction line data to this.
