Create Regions

[ashrafa33]

I have more than 1000 polyline 

when icreate REGION using regions = Region.CreateFromCurves(curves);

i get "Autodesk.AutoCAD.Runtime.Exception: eInvalidInput"

how i can Know where is my error

i want to know where i have open region or self-intersection

i think it is open or self-intersection less than 0.001 m

i wnat to find this point

i try it before

try catch give me

 Autodesk.AutoCAD.Runtime.Exception: eInvalidInput at
Autodesk.AutoCAD.DatabaseServices.Region.CreateFromCurves(DBObjectCollection
curveSegments)
at select.Select_Polylines.region_create() in .................:line 1050

it dose not give me where it is open or self-intersection

my polylines was arcs & line i convert them polylines list

to delete duplicted  and laping items then i try to make region

so they are not closed polylines

Try to join lines and arc  Get polyline through Comment join 

Does it work?

You must attached example drawing

And some code

Maybe you have a double in vertex ?

Maybe you have a double in vertex ?

Or arc's where the Tangents do not match the other end.

Seen these errors a lot for imported DXF files where the tangents of the rounded corners of rectangles have small rounding error (e.q. 89.9999 degrees).

Solution: Move these open endpoints en then move them back to the closing point.
