Many BricsCAD users who handle geospatial information need to work with Esri Shapefiles (SHP), by downloading these files from the web or by collaborating with others GIS users, and their basic need is to import these kinds of files into BricsCAD by transforming the Shapefiles features into BricsCAD Entities
A Shapefile (SHP) is a digital vector storage format for storing geometric location and associated attribute information. Shapefiles (SHP) are simple because they store the primitive geometric data types of points, lines, and polygons. They are of limited use without any attributes to specify what they represent. Therefore, a table of records will store properties/attributes for each primitive shape in the Shapefile. Shapes (points/lines/polygons) together with data attributes can infinitely create many representations about geographic data
Shapefile to CAD
When converting SHP to CAD files the following considerations have to be taken into account:
· 3D features in the Shapefiles must be converted to 3D CAD Entities (Points, Polylines, etc.) or to pseudo-3D CAD Entities considering the elevation and the thickness of the Entities
· When importing Point features It is very interesting to use complex CAD Entities (such as Block references in BricsCAD) which can include variable text information (such as Attributes in BricsCAD)
· We must also consider the importing of complex Polygon features, which may include more than one internal or external ring, and convert them to appropriate CAD Entities (such as Hatches in BricsCAD)
· What is also very interesting is the automatic distribution of the Entities across the drawing depending on the values associated to the Shapefile features (using, for example Layers in BricsCAD)
· Finally, we consider some system able to import and display the features alphanumeric data (such as Extended Entity Data -EED- in BricsCAD)

Import Shapefiles to BricsCAD
Spatial Manager™ for BricsCAD lets you import graphic Entities into BricsCAD from a large number of GIS sources including Esri shapefile format
The application detects what type of information the shapefile contains to import (points, lines or polygons) and presents to the user only those import options that are valid for that type of Entity. In the case of polygonal Entities, the closed borders can be automatically filled by using BricsCAD Hatches, or import not only the border of the polygons but also their centroids by using Points or BricsCAD Blocks
For any imported table or file, regardless of its format or type, it is possible to automatically subdivide the imported Entities into various BricsCAD Layers, according to the value of a field in the source data table
How to import shapefiles into BricsCAD
This example shows how to import Shapefiles into BricsCAD using Spatial Manager™ for BricsCAD. In the video you can see how an SHP Parcels file is imported onto a drawing, which already contains other Entities belonging to a city
The import process fills every Parcel using a Solid transparent Hatch, distributes every Parcel into new Layers according to the zones to which each Parcel belongs and applies random colors for every new Layer created. The alphanumeric data of every Parcel is also imported using BricsCAD Extended Entity Data (EED)!
