To transfer the polyline from the layout or profile to the cross sections, select the Draw Projection Points command (41K2).
From the list of the projection lines, select the line to insert in the cross-sections.
If you select the Lines without elevation interpolate on terrain checkbox, then the intersection points without elevation will be interpolated on the terrain line. If the option is not selected, the intersection points without elevation will be drawn at the bottom of the cross-section.
If you want to insert the AutoCAD block that symbolizes a certain object, check the Insert block with intersection point name check box. The block name must be the same as the name of the intersection line and it must be on one of the AutoCAD search ways. The search ways are defined with the Options command.
