Topo Align contains 4 commands to assist in working with topo surfaces.
Align to Element
Pick elements (walls, floors, roofs, pads) and align topo surfaces to either the top or bottom face with variable vertical offsets to avoid coincident surfaces if required.
You can also align topo surfaces to individual edges and some limited support for aligning topo surfaces to families. There is still an early attempt at cleaning up (removing) existing topo points that are within the plan area of the element being used for the align. The results are mixed for very complex elements and some manual processing may still be required.
Points from Lines
Draw model lines and arcs BELOW the topo surface and use this tool to project them onto the topo surface as additional topo points. This is useful when grading regions of the site and you don’t want any topo surface manipulation beyond a given point. If the lines selected from a closed loop you are asked if you want to remove the existing topo points within the plan shape.
Points along contours
Draw model lines as contours lines on levels/reference planes where you want to precisely control the proposed contour of the topo. The command will prompt you to select the topo surface and then the contours lines. Topo points will be created along the model lines at the specified distances.
This works in a plan view and will remove internal topo points from an edited topo surface and then copy the points inside the area picked from an existing topo surface. Effectively an undo edits for part of a graded surface. This will not reset boundary points. It is recommended that if multiple topo surfaces are used in a project that they are named to assist in picking them from drop downs.
