How to import ESRI Shapefile (*.shp)

#1
We currently do not support ​Shapefiles directly at CMS IntelliCAD 9.2.

​Shapefile is a legacy format of Esri to describe geo-referenced GIS features (points, lines, polygons and limited multipatches). It has limited support for GIS attributes and should be considered superseded by Esri FileGDB.

​You can use the QGIS freeware to import shape files in to layers and then export them as .dxf file. Such file can then be open using CMS IntelliCAD.

Here's how:
Open QGIS and click LAYER > ADD LAYER > ADD VECTOR LAYER.
Select the zipped shapefile.
Click on OPEN.
Go to PROJECT > Import / Export > Export Project to .DXF

You can download QGIS from https://qgis.org/en/site/forusers/download.html
