STL2GDS Revision History



Version 1.33 10/03/2021

Numerical Filtering Addition

Single DBU (database unit) filtering for nearly collinear lines is applied on output. This filtering removes "artifacts" created where facets share edges as a result of rounding when going from "real world" coordinates in STL to gridded spaces like GDSII and Gerber when the coordinates are integral.




Version 1.32 1/27/2021

Licensing Update

Added Softkey licensing for OEM.




Version 1.31 5/12/2020

Software Updates

The following new and improved features were added to the translator:
Only non-empty layers are output
Better start/stop elevations chosen with Auto-slicing mode
GDSII layer numbers and Gerber output files are associated with elevation at the end of the log file.

Configuration menu GUI New Features

There are two new options in the Configuration menu:
Added a new configuration option "Join Volumes Post-Creation" for post-union.
Added "Optional Arguments" field (mostly for debug purposes).

Slice menu GUI New Features

There are new options in the Slicing menu:
Sets default direction to the direction with smallest data extents.
Slice Count control added for easier slice configurations.
Changing any values of Start/Increment/SliceCount/Stop will dynamically adjust other values.
Reset button added to revert back to default slicing configuration.




Version 1.29 2/11/2020

New 64 Bit

Major release after 3 years. This version is 64 bit and it is compiled with Microsoft VS2015.
stl2x is now based on the new booldll.




Version 1.28 10/14/2017

Flexlm Floating Error

Fixed a problem where stl2gds was not able to get a floating license from the server.




Version 1.26 3/1/16

Auto Detect STL file

STL reader auto-detects Endianess for binary STL files.
This version core engines/shell recompiled in VS2008.




Version 1.25b 11/27/14

New Install

This version includes the new install.




Version 1.25 10/20/12

Enhanced Linking

Added Enhanced Linking Control to Configure Dialog.
Removed "Ignore Facet Normals" Control from Configure Dialog It turns out that the normals provided are always ignored, and they are computed internally.




Version 1.24 10/27/11

New Multibody Control to Configure Dialog

This control when set will unionize incoming data. It is off by default.




Version 1.23 04/07/11

Ignore Facet Normals

Added "Ignore Facet Normals" Control to Configure Dialog.




Version 1.17 10/8/05

Fix Re-entrant polygon routine

An error in routine that converts voids to re-entrant polygons, produced some illegal polgyons in the GDSII data. This has been corrected. [Reported by Texas Instruments]




Version 1.16 03/28/05

Slicing Algorithm Corrected

An error in the slicing algorithm produced some illegal polgyons in the GDSII data. This has been corrected. [Reported by NASA]




Version 1.15 03/17/05

GUI

The graphical user inteface for stl2gds has been added in this release.




Version 1.14 03/01/05

command line fix

Version 1.13 did not support both cases for the units option i.e. -units:mm was not interpreted correctly (it was expecting -units:MM) and actually wrote the output file in inches. This has been fixed.




Version 1.13 02/20/05

Initial Release
