CREATING MULTIPLE POLYGON BOUNDARY

[shil143]

Please help to create multiple boundary for between polylines...

Do you need polylines to have different Elevations? Look at the left or the like.

In my opinion, the General scheme is as follows:
1. Drawing Cleanup (MAPCLEAN):

Converting Lines, Arcs, 3DPolylines to regular Polylines can also be done in MAPCLEAN:

Sometimes MAPCLEAN needs to be run multiple times. Sometimes with different actions. It depends on the source data.
And better control in Interactive mode.
The tolerance depends on the accuracy required.
2. Create an areal topological model - MAPTOPOCREATE.
3. If it is necessary to unload from this model areas (closed polylines, in groups - if polygons are complex) - MAPCLPLINE.

This sometimes requires painstaking work and attention. Sometimes not everything is clear when managing topological models. But it works, and precise areal objects are obtained.

Hi @АлексЮстасу ,

one additional command which might close the loop: _MapTopologyToPolygons

Create closed Polylines from Topology objects.

Mapexport to a sdf file selecting polygons and select all the line work.

The attached file is the result with elevations to zero.

everything else needs drafting corrections.  there are over lapping area, unclosed intersections, other drafting errors.

Yes, this is the MAPCLPLINE command - my item 3.

Hi @АлексЮстасу,

yes, the result of both is the same 🙂 and sorry not realizing the second command.

 Sorry!
I misunderstood you! I thought your "MapTopologyToPolygons" is the name of the action, not the command.
I did not think that there are two commands that do the same thing - MAPCLPLINE and MAPTOPOLOGYTOPOLYGONS.
Or are these commands somewhat different?
