Hi sirs/madames ,

 

Anyone knows how to split some polygons that seem to be created under the same polyline?

 

I have world map in .dwg but I would like to remove the small islands to print and cut it into a wood panel.

 

Here there is an example:

Thank you!

Hi,

 

a polyline is ONE object, so whatever your picture shows, it isn't just a normal polyline with usual properties .

 

Select the object, open your properties palette [CTRL]+[1]

Check out the Object type (listed first on top of the palette)

 

Looks like a HATCH or MPolygon.

 

You are working with AutoCAD?

PROPERTIES command says what about what you selected at the very top? Show us please, "polygon" is too generic a term for what you screenshot here.

Use the SEPARATES HATCHES option from the Hatch ribbon

Hi again,

 

Thank you for your quick answers sirs.

 

Yes, it is an MPolygon. Excuse my mistake.

"Splitting" and "removing" are very different.  Post a small drawing file, clearly marking what you want to split [and what that means], what you want to remove, and how the two relate to each other.

@sergiowaitforit Are you using MAP3D or Civl3D? You are in the wrong forum for both of those software and editing that object type.

I would like to delete these islands for example:

I don't have the software overlay to work with MPolygons [see Message 7], but if they're like Hatches as implied by other replies, does it work to draw a big Circle around those islands, and use it as a cutting boundary in a TRIM command?

Select your mpoly,

use EXPLODE command

and if you like to have the filling back, create new hatchs for it:

 

command Hatch

The HatchEditor tab is current now,

entlarge the panel "Options"  and make sure your option "separate hatchs" is ON.

Object<Select> option

and if Acad ask for objects, type in:

P<followed by enter><followed by enter>
