Autocad create polyline boundary

In the Hatch Edit dialog box, click Recreate Boundary. When you see the prompt "Enter type boundary object", enter P for polyline or R for region. When prompted, choose whether or not to associate the hatch with the new boundary. Get answers fast from Autodesk support staff and product experts in the forums.

For a variety of applications, the Boundary feature provides powerful capabilities to generate outlines and profiles in a drawing quickly and efficiently. Typical applications include the following: Generating a foundation plan from a residential floor plan Finding the area and perimeter of an enclosed area such as within a plat map Using polylines to create complex region objects for 2D Boolean operations and extracting the 2D centroid, moments of inertia, and other 2D data Creating a polyline profile for 3D operations such as extruding, sweeping, and revolving Self-Guided Demo The purpose of the following steps is to generate closed polylines from an area enclosed by contiguous or overlapping objects.

Create some geometry as shown below. Note: With complex boundaries, you might need to zoom in to the desired area to avoid error messages. You have a drawing that contains hatches with boundaries, and you want to recreate the boundaries or remove a section of the hatch pattern.

Select the hatch. In the Hatch Edit dialog box, click Recreate Boundary. Today there is no mechanism to edit multiple hatches at the same time. This command will generate a new closed polyline boundary around the hatch. Select the hatch object. Make any changes you want and watch the real-time preview as you do. Define the Hatch Boundaries. Once the Hatch object is created, the hatch boundaries can be added.

Boundaries can be any combination of lines, arcs, circles, 2D polylines, ellipses, splines, and regions. The first boundary added must be the outer boundary, which defines the outermost limits to be filled by the hatch.

Filter by Lables. Message 1 of 2. Create boundary or measure area of 3D polyline. I am trying to measure the area of a group of 3D polylines which share endpoints but are separate entities these form a lake elevation contour. I have tried to join them thru pedit but it won't let me. I have tried to create a boundary but also to no avail.
