An MPolygon, short for MultiPolygon, is a geometric object in AutoCAD that represents multiple closed polygons. It is commonly used in various applications, such as civil engineering and architecture, to represent complex shapes or areas with multiple boundaries. In this article, we will explore the concept of MPolygon in AutoCAD and understand how to create and manipulate them.
Creating an MPolygon
To create an MPolygon in AutoCAD, you can use the MPOLYGON command or the MPOLYGON option within the POLYGON command. Here’s how:
-
Select the MPOLYGON command from the AutoCAD ribbon or enter “MPOLYGON” in the command line.
-
Specify the first point of the first polygon by clicking on a point in the drawing area.
-
Continue specifying points to define the first polygon, either by entering coordinates or using object snaps.
-
To add more polygons to the MPolygon, press Enter or right-click and choose “Close Multipolygon.” Then specify the next point for each subsequent polygon.
-
To complete the MPolygon creation, press Enter twice or right-click and choose “Exit.”
Manipulating an MPolygon
An MPolygon can be easily manipulated using various editing commands available in AutoCAD. Here are some common operations:
Moving an MPolygon
To move an existing MPolygon to a different location:
-
Select the MOVE command from the AutoCAD ribbon or enter “MOVE” in the command line.
-
Select the MPolygon you want to move.
-
Specify a base point for the move operation.
-
Specify a second point to determine the displacement or enter specific coordinates.
Scaling an MPolygon
To scale an MPolygon, changing its size proportionally:
-
Select the SCALE command from the AutoCAD ribbon or enter “SCALE” in the command line.
-
Select the MPolygon you want to scale.
-
Specify a base point for scaling or use “Reference” to specify a reference length.
-
Enter a scale factor, such as “2” for doubling the size or “0.5” for halving it.
Rotating an MPolygon
To rotate an MPolygon to a specific angle:
-
Select the ROTATE command from the AutoCAD ribbon or enter “ROTATE” in the command line.
-
Select the MPolygon you want to rotate.
-
Specify a base point for rotation.
-
Specify a second point that determines the rotation angle or enter an angle value directly.
Closing Thoughts
An MPolygon is a powerful geometric object in AutoCAD that allows you to represent complex shapes with multiple polygons. By understanding how to create and manipulate MPolygons, you can efficiently work with intricate designs and accurately represent areas with various boundaries.
Remember to experiment with different commands and explore the vast capabilities of AutoCAD to enhance your productivity in creating and editing MPolygons.
