Break down project into manageable chunks by creating Construction Work Area.

Work Area can be created by:

• selecting an alignment. Tool allows to define length, offset and tool will slice all elements crossing Work Area boundary. Only visible 3d elements will be sliced.
• drawing custom polygon. Visible elements that cross this polygon will be sliced and will be added to Work Area.
• adding individual elements
• selecting existing 2d design shape

As a result Work Area object is created with a 3D elements relationship that belong to Work Area.

Recommendation is to create Work Areas before cost codes assignment as Work Areas creation might remove assignments.

From alignment:

Drawing custom polygon:
'Work area from graphics' tool allow to draw a custom polygon, all visible elements intersecting polygon's boundaries will be sliced. As a result Work area is created with elements from defined polygon.

Tool also allows adding individual elements into Work area.

Select existing 2d design shape

Select existing 2d design shape to create Work Area with boundary of selected shape.
