Lock Down Shared Coordinate Relationships

The more complicated a project is the more trouble someone casually (accidentally) moving a building file can create. The simplest solution is to pin a linked model to interfere with accidental movement. Moving a pinned link takes a deliberate action.

We can put another speed bump in the road by using Worksets as a security guard to make it harder to move a linked file. Assign each link to its own workset and then create a new username like "Link Admin" and while working as this user make each link's workset editable (take ownership of each link's workset). When you synchronize (SwC) don't relinquish those worksets. Next time someone accidentally drags a linked file they'll be warned that "Link Admin says no".

One more step you can take which also involves worksets is to make the Project Info workset editable too, for each building file. The Project Info workset is located in the Project Standards group.

Taking this approach prevents shared coordinates from being altered inadvertently or otherwise. Same strategy, same user, same refusal to relinquish the worksets this user borrowed. This needs to be done in all the linked models as well as a master site model if used to establish the shared coordinates.

Five Minutes with a Toposurface

I created a video to describe what happens when Revit contours don't quite match up with the underlying cad file contours that were used to generate a toposurface. The first part of the video explains that the Site Settings usually don't match the contour interval settings of the cad source file. Changing these settings is often enough.

When we want Revit to provide more contours than the source file provides it can but that's where we start getting some distortion of the contour lines we see. The rest of the video shows how to manipulate the contour lines with additional points to help Revit sort it all out.

Keep in mind that Revit creates triangles between points. You can see these if you use Visibility/Graphics to turn them on.

This is what the triangulation looks like before adding an extra point to help Revit draw the contour more accurately.

This is what the triangulation looks like after adding the extra point.

Property and Setback Boundaries

I wrote a couple posts before about documenting these. The first was about using the property line tool to create the setback lines too. I used Override Elements in View to make the line pattern different. The second was dealing with the notion of 3D representation of these boundaries. Have a look if you are seeking ideas for these site and property documentation issues.
