How do you create a route that mixes Direct and Autorouting sections? This has come up before (I posted on the topic here). Thought I'd post a followup.
The scenario is this: sometimes while building a route using waypoints, you can use autorouting for 95% of a route, only to find some small part must be direct routed, typically a few miles. Examples include taking a ferry, or an offroad segment that is not on the map, or a new roadway not shown on the older map data, or a road that is incorrectly marked as a trail, etc.
Today the only reliable solution for Mac Basecamp is to split the route into three routes, Part1(Auto), Part2(Direct), Part3(Auto) etc. and then load each route while underway. This gets tedious!
There are temporary workarounds e.g. switching to the global map, or, even more tantalizing, switching routing mode while using the route tool. However, when you then export and import the route, or edit the route's waypoints, or change settings in Basecamp, the route gets recalculated and the direct-routed sections magically become auto-routed, resulting in chaos.
These workarounds show how frustratingly close Mac Basecamp is to supporting mixed auto-routing and direct-routing in a single route. In fact, if you look in the GPX file, you can see each Waypoint has a "CalculationMode" extension, but this attribute is not sticky enough - the route preferences seem to override the per-waypoint settings. There is no way to say "Always direct route this waypoint".
(Of course, a separate question is what happens when you load such routes on a Garmin Zumo...!)
Does anyone else need this feature?
