AS4CAD_V1.3.2 out now!
AS4CAD is an open source solution for automated archaeological feature drawings from in-field GNSS / totalstation point measurements directly in AutoCAD and BricsCAD.
It is designed as a single, adjustable AutoLISP script - no plugin installation, no separate pipeline file.
AS4CAD is an AutoLISP reimplementation of the AS4QGIS Synthesis workflow, built for direct use inside AutoCAD and BricsCAD.
AS4CAD works on the basis of point data exported as delimited text from a surveying device.
It processes 10-character pointID-strings: e. g. 0001A03001
feature 1
line container / point property A
shape type 03
sequence number 001
Depending on the entered "shape type", AS4CAD generates classified CAD geometry directly in the drawing:
polygons and polylines (true 3D geometry, correct elevation per vertex)
point data (styled, attributed block symbols)
vertices (marker blocks along every line/polygon)
shape type spectrum:
feature | 01 - heights, 02 - polyline, 03 - polygon, 33 - closed polyline
sample | 51 - sample point, 52 - sample polyline, 53 - sample polygon
posthole | 06 / 61 - buffered point measurement
finds | 71 - find point, 72 - find polyline, 73 - find polygon
3D markers | 81 - 3D marker point
trench | 91 - fixed point, 92 - trench polyline, 93 trench polygon
section nails | 00 - section nail point
AS4CAD currently covers the Synthesis side of the AS4QGIS suite only; there is no Psyche equivalent yet (adding the same attribute structure to pre-existing CAD lines/polygons).
AS4CAD is free to use (MIT license) and fully customizable. The AutoLISP script is available for download here...
