This system variable controls how the joints between polyline segments are created.

If the “Offsetgaptype” variable is set to 0 which is the default, the polyline segments are extended to fill the potential gaps between the segments. 

Using an offset distance of 250 and offsetting the polyline to the outside the results are below.


Changing the “Offsetgaptype” to 1 the potential gaps between the polyline seggments are now created as fillets as below. The fillet radius is the same as the offset value.





Changing the “Offsetgaptype” to 2 the potential gaps between the polyline segments are now created as chamfers as below.





The polyline does chamfer, however the results may not be as expected; the chamfer is created perpendicular to the joint.
