The 18th Christmas CAD freeware giveaway by Arkance Systems

The Year 2021 is coming to its end, the Christmas time, so we at Arkance Systems CZ (former CAD Studio) have decided to continue our tradition and again give out decorated presents - our free tools for all CAD users, so they can extend capabilities of their Autodesk design software. But do not miss also hundreds of other useful CAD applications, web tools and CAD/BIM libraries offered for free on our portal

As a part of the tradition, this year's Christmas-tree utilities by Arkance Systems include (all can be downloaded from Freeware):

  • ScaleBB/RotateBB - a LISP application for AutoCAD - scales or rotates multiple objects in relation to their individual reference points or bounding boxes. See the Tip

  • CopyBlockE - allows to copy-in a selected "borrowed" block from an external DWG file into your current AutoCAD drawing, or update that block from the foreign DWG, while maintaining its attribute values. Supports also dynamic blocks. See the Tip
  • GeoCode - to our AutoCAD app for forward- and reverse geocoding (conversion of address/location), we have added the support of the API of the what3words mapping service and an easier link to Google Maps - see the app page

  • RRename - an enhanced version of the AutoCAD app for mass renaming of layers, blocks, layouts, linetypes, style, groups or Civil objects using regular expressions - now supports more object types and allows global (multiple) string replacements. See the Tip
  • GeoRefImg - one of our most popular freeware apps, now allows to insert images directly with automatic placement to their georeference position, scale and rotation (by their World file), including mass-insertion. See the app page
  • CADexcel - we didn't forget AutoCAD LT users, this add-on for MS Excel allows mass import of XY/XYZ coordinates from an Excel sheet into AutoCAD (LT) - as points, polylines or blocks. See the Tip
  • Snake - modified two variants of the interactive game "Snake" in Visual LISP for AutoCAD
  • F360 Diry (Holes) - a useful plug-in module for Fusion 360 - bulk-selects all faces of the same color (according to an example), creates a selection set from them, which you can then use e.g. for CAM operations. See Download.

  • najdiDiry (findHoles) - an iLogic macro for Inventor, also locates holes, on the first solid in the current IPT document. After you select the holes, you can e.g. change their color or bulk-change their diameter using direct editing. See Download
  • exportujPlechy (exportSheetmetal) - an iLogic macro for Inventor - bulk-exports all sheetmetal unfolded shapes from an assembly into DXF, with preset settings, explained in the Tip, for download on Download
  • SelectParentOccurrence – a simple iLogic macro - in an Inventor assembly model, selects the parent component. See Download
  • HELUZ - in cooperation with HELUZ, we have prepared a gift for designers in the BIM application Revit - the application "HELUZ Lintels" inserts and displays the structural elements of lintels and additional bricks of the lining into the model in Revit. It also produces layout plans, documents for construction companies. See details and download (in Czech)
  • Converters - we have also extended function of the Converter section on - so e.g. the online converter of mapping coordinates now supports the German coordinate system Gauss-Krüger. The new web app BarCode generates CAD versions of various types of barcodes. The IFC viewer displays you BIM model in the IFC file format - online, without installing any viewer software. See CADforum - Converters


- and many useful functions (parts are free, not only for customers) offered in our Arkance Systems bonus tools - "CS+":

  • InventorTools ("X-Tools", X-Tools LT) - additional tools for Inventor users
  • RevitTools (aka Holixa Tools for Revit) - set of useful BIM tools for Autodesk Revit
  • CivilTools - set of useful tools for Autodesk Civil 3D
  • PlantTools - set of useful tools for the piping software AutoCAD Plant 3D
  • VaultTools - set of useful tools for the PDM software Autodesk Vault
  • PowerTools - set of useful tools for the CAM software Autodesk PowerMill
  • FeatureTools - set of useful tools for the CAM software Autodesk FeatureCAM
  • FusionTools ("F-Tools") - additional tools for users of the CAD/CAM/CAE software Autodesk Fusion 360

And as usual - all these CAD utilities (and many other) can be found for download on our Freeware download page, some also on Autodesk Apps - or you can still try to write a letter to Santa Arkance Systems.

Best Wishes for 2022

Let's build 2022 together!
