Import SHP files 3D and extrude buildings

Hi,

 

I am a brand new user of Autocad 3DMap 2015 . I wonder if it is possible to get some help for the following procedure :

 

Import shp file containing buildings and 3D attributes for its height .

 

Visualize those attributes

 

Extrude the buildings elevation.

 

 

Thanks in advance .

 

 

VG

Hi,

 

>> Import shp file containing buildings and 3D attributes for its height .

Use command _MAPIMPORT to import the geometry or command _MAPCONNECT to connect to the SHP file.

 

>> Visualize those attributes

Which attributes?

Using _MAPCONNECT you can use the stylization to create lables, but if you mean "labeling" when you write about "visualize attribtues"? I don't know.

 

>> Extrude the buildings elevation.

You can look to that video (using first _MAPIMPORT with object-data, then ADEQUERY to create objects with modifying the property THICKNESS (instead of ELEVATION as shown in the video.

 

>>>click for video<<< you can jump over the creation of the contours, start at command _MAPIMPORT.

Let me improve the tip about querying by Thickness, gentlemen.

A thick polyline is not an extruded one, but only an "empty inside" 2.5D object.

To transform into a "true" solid, you should use the _CONVTOSOLID command.

Take a look at this old blog post.

Hello ,

 

 

I come back again with this topic, because I was  trying to repeat the workflow for the extrusion of 3D buildings and i am having an issue.

 

When  i am creating  the  query   , Choose Location All, when i choose  Alter properties for Thickness and select expression button, I am not seeing object data neither object properties !  ( in attach the form where it is missing the object data and object properties)

 

Someone could help to fix this issue ?

 

Thanks in advance,

Upon _MAPIMPORTing, ensure you checked this out:

Hi,

 

 

I used the procedures that you mentioned but iI  am still unable to see the data properties and the object properties .

 

I have also tried different files but they have all the same problem.

 

 

Any suggestion ?

Hi,

 

you should have changed the option in the MAPIMPORT dialog to use (closed) polylines while importing polygons. Otherwise MAPIMPORT creates MPOLYGON-objects and these can't be extruded.
