For Lineardraft to recognise the tracks associated with a heavily skewed portal, an adjustment to the Project Settings may be required. This is to compensate for the increased track gauge as measured along the length of the portal.
The Lineardraft Nominated Contact within your company can request this change by submitting a Support Ticket.
Details on how Lineardraft measures track gauge can be found here: "How does Lineardraft measure Track Gauge?"
