Topic: How to avoid arcs in pline while doing offset

[subbup]

Hello All,

I have a lwpolyline processed with only straight lines.
But when I do offset of that lwpolyline I am getting arcs in new entity.
COuld any one tell me how to avoid or control this.

Have a look at the
OFFSETGAPTYPE System Variable

What is your currents value ? Try Setting it to 0

Controls how potential gaps between segments are treated when polylines are offset.

0 Fills the gaps by extending the polyline segments

1 Fills the gaps with filleted arc segments (the radius of each arc segment is equal to the offset distance)

2 Fills the gaps with chamfered line segments (the perpendicular distance to each chamfer is equal to the offset distance)

I tried with this variable. Even after setting this variable to 0 still
the arcs are coming.

Did you create the polyline yourself?  I've seen some things (for example, centerlines imported from MX) that have extremely small radiuses inserted at every "angle point".  This removes "dead space" in stationing - areas with no station/offset because of an angle in the alignment - at the cost of more complex calculations in a number of other areas.

You may want to type "list" and select the polyline, if you haven't already, and make sure there are no really tiny radiuses in there...

Hai Sinc,

I checked the polyline whether it contains any arcs with the help of listing the plyline. I didn't see any thing related to bulge.
This polyline is created by filleting two polylines.

What is your fillet distance set to?
