The following extensions are currently supported by PlanSwift: 

.TIF

.PDF (Adobe)

.DXF

.DWG (AutoCAD) 

.PLN (Dodge plan files)

.JPG

PlanSwift also supports .DWF file format; however, because this format is used in so many different ways, PlanSwift can have trouble importing the plans.

TIF is the preferred image file format for use within PlanSwift.
