AutoClass - automatic classification of object properties

Sort selected DWG objects into individual categories based on their properties


AutoClass - object classification for AutoCAD

AutoClass promnpts AUTOCLASS is a tool for classification (grouping) of DWG objects in AutoCAD. It sorts selected objects into individual categories based on their common property - like Elevation, Area, Length, Volume, Radius, Rotation, etc. The individual categories (classes) are represented by colors (multiple palettes are offered - rainbow, hydro, green, pastel...) or by automatically created layers - like AUTOCLASS_RADIUS_10_19, AUTOCLASS_RADIUS_20-29, etc. You can also use special properties RefPointZ (Z-coordinate of the object's reference point), PtDistance (distance to specified point) and block attribute values (numeric).

Just load the AUTOCLASS.VLX using APPLOAD or ACADDOC.LSP and start the AUTOCLASS command. Select objects to classify and AutoClass offers all common properties of these objects. Choose any property and AutoClass scans the objects for minimum and maximum values (extremes). Select the color- or layer-classification method. For color classification, choose one of the preset palettes. For layer classification, specify the number of classes or their range (interval size). Layers in the form:

AUTOCLASS_property_from_to

will be created automatically and the objects will be moved into these layers.

You can use AutoClass e.g. to color 3DFACE terrain models, dissect points according to their elevations, mark parcels by their lot areas or solids by their volume.

Samples

AutoClass
Classification of RefPointZ for 3DFACEs, BigRainbow palette + layer classes

AutoClass
Classification of RefPointZ for 3DFACEs, Hydro palette + layer classes

AutoClass
Classification of ptDistance for 3DFACEs (to the upper-right point), BigRainbow palette + layer classes

AutoClass
Source drawing for Length & Area classification

AutoClass
Classification of Length and Area for LINEs and HATCHes, BigRainbow palette + layer classes


Classification of point elevations, BigRainbow palette

List of preset properties:

  • Length (e.g. LINE, POLYLINE, SPLINE)
  • Area (e.g. POLYLINE, REGION, CIRCLE)
  • Volume (3D solids)
  • Elevation
  • Thickness (3D)
  • Rotation (blocks)
  • Height (texts)
  • Radius (circles, arcs)
  • XScaleFactor (blocks)
  • Measurement (dimensions)
  • ConstantWidth (polylines, donuts)
  • Perimeter (regions, circles)
  • Centroid-z (3D objects - Z of their centroid)
  • ptDistance (distance to reference point)
  • refpointZ (Z of the reference point, centroid for 3DFACEs and 3DPOLYLINEs)
  • numeric attribute values (blocks)


NB: You can change the layer prefix by setting the LISP variable:
(setq _AUTOCLASSLAYERPREFIX "MYLASS")

Supported platforms

AutoClass was tested on AutoCAD 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015, 2014, 32-bit and 64-bit. Other versions will probably also work.

History

  • Version 1.0 (1/2016) - First release
  • Version 1.1 (10/2012) - Added block attributes, fixed integer properties

AutoClass license (trial + buy/order)

In the trial version you cannot use other object properties than RefPointZ, Length, Area and block attributes. The number of classified objects is limited to 100.
