This parameter specifies the maximum number of The Maximum Triangle Strip Size value must be 3 or larger. Planimetric and surface area calculations are included in the output alongside other attributes from the input polygon.Ĭonsider converting polygons to multipatches if you experience display problems with three-dimensional rendering of polygons draped on a surface. Resulting multipatch will capture the 3D surface representation in its geometry.

The triangles of this new TIN are then extracted in a series of strips that are used to define a multipatch-based feature. The nodes are re-triangulated in a new memory-based TIN, and the 3D polygon boundary is enforced as a clip polygon. Then, all nodes that fall within the polygon are extracted.

This natural densification captures the full definition of the linear surface using a minimal number of samples. Heights are obtained using linear interpolation by sampling at each input vertex and wherever the boundary line intersects surface triangle edges and nodes. UsageĮach polygon feature has its boundary profiled along the surface. For more information, refer to: Multipatch Footprint.Creates surface-conforming multipatch features by draping polygon features over a surface. Use the Multipatch Footprint tool to convert 3D multipatch features to 2D features.

Click Editor > Stop Editing to stop the edit mode.

In the Editor toolbar, click Editor > Save Edits to save the edits.

The Copy and Paste functions are also accessible through the Edit menu by clicking Edit > Copy or Edit > Paste. In the Paste dialog box, select the 2D shapefile as the Target, and click OK.

Click Paste to paste the copied features along with the attributes to the 2D shapefile.

In the Standard toolbar, click Copy to copy the selected features.

Select all features in the 3D shapefile by right-clicking the 3D layer in Table Of Contents > Selection > Select All.

In the Editor toolbar, click Start Editing to start editing on the new 2D shapefile.

A new 2D shapefile is created and added to Table Of Contents.

For Coordinate System, import the spatial reference of the 3D shapefile.

Leave the Has M and Has Z parameters as DISABLED.

This step pastes the feature over all attribute fields.

For Template Feature Class, select the existing 3D shapefile.

For example, select POLYGON if the 3D shapefile contains polygon features. The geometry type of the output shapefile must be the same as the 3D shapefile.

Specify the Geometry Type of the output 2D shapefile.

Specify the Feature Class Location and Feature Class Name for the output 2D shapefile.

Open ArcToolbox and navigate to Data Management Tools > Feature Class > Create Feature Class.

Create a new 2D shapefile using the Create Feature Class tool.

To convert a 3D shapefile to a 2D shapefile, follow the steps below: ProcedureĬonvert 3D point, line and polygon features

This article provides the instructions on how to convert 3D shapefiles to 2D shapefiles in ArcMap. In some instances, a 3D shapefile containing 3D features must be converted to a 2D shapefile for further data analysis that requires 2D features. How To: Convert 3D shapefiles to 2D shapefiles Summary
