Here are 12 variants of TSP*.lsp files... First one : TSP.lsp - wrapper for grid and rnd disposition - LISP and ObjectARX... Second one : TSP-ALL.lsp - gathered plenty of subfunctions to pull out best results by permutations of point clouds... Third one : TSP-cheapestpath.lsp - Similar to TSP.lsp (wrapper) but without choosing for grid and rnd dispositions... Fourth one : TSP-MMR.lsp - fast grid and rnd disposition with Evgeniy Elpanov's optimization with 2 factor permutation... Fifth one : TSP-MR-AROUND-CONCAVE.lsp - very nice little routine to make stars from radially disposition of points... Sixth one : TSP3D-ACO - Ant Colony Optimization for Traveling Salesperson Problem for 3d points or picked polyline... Seventh one : TSP3D-FAST - Simple and fast tsp for 3d points... Eight one : TSP3D-GENETIC-NEW - Simplified 3d Genetic Algorithm for 3d points or picked polyline... Ninth one : TSP3D-SOLVER - Small and simple tsp for 3d points... Tenth one : TSP3D-tsptour_lsp-new - Basic 3d TSP that combines both grid and rnd 3d points dispositions... Eleventh one : TSP3D-tsptour_lsp-new+solver+fast - Powerful version that combines TSP3D-tsptour_lsp-new, TSP3D-FAST and TSP3D-SOLVER... IMHO, the best of both worlds speed of execution and shortness of resulting 3d polyline... Twelfth one : TSP-HeldKarp.lsp - HeldKarp algorithm for AutoLISP... Gives shortest result, but for up to 20 3d points Big thanks to Daniel from www.theswamp.org for providing *.arx and *.brx files for AutoCAD 2025 and BricsCAD V25... More info and newly added *.arx, *.brx, ... at this link : https://www.theswamp.org/index.php?topic=58049.0 HTH. M.R.

Are you someone who likes to get details in your drawings done neatly? Then look no further! Here I present you a program that does just that. This program aligns selected objects to any direction the user wants to align them to. This provides that the objects possess at least one of the following properties: Insertion Point Text Position Text Alignment Position Center Upon issuing the command ATD, the user will be prompted a selection of objects without any filters, which the program will then filter based on the above (and xrefs excluded). The objects to be aligned will then be highlighted, and the user will be prompted a direction relative to the UCS. This can be in one of five ways: Clicking two points to determine direction Typing "X" - to align direction to X axis of UCS. Typing "Y" - to align direction to Y axis of UCS. Typing "PErpendicularToCurve" - the user specifies a point on any curve, and if a curve is detected, aligns perpendicular to the curve at that point. Typing "ALongCurve" - the user specifies a point on any curve, and if a curve is detected, aligns at the direction of the curve at that point Curve detection is compatible within all sorts of complex objects, such as nested blocks (with dynamic properties), xrefs, tables, dimensions, etc. regardless of depth, and fully functional under all UCS. Following this, the user can then specify an optional distance that would be used to align the objects, or choose the "Through" option. This makes up an exactly identical feature to the built-in AutoCAD OFFSET command. If a distance is specified, the user will also be specified a point that will be used to calculate the specified distance away from the point. If "Through" is chosen, the user will then be prompted the point to place the objects. If the distance has been chosen and specified, the user can click on the side that the user wishes to place the objects at that distance from the point. Objects that I've successfully worked with this program include: Tables Blocks OLE/Raster images Dimensions Texts and MTexts (regardless of alignment) Circles This program will work under any UCS settings provided that the objects to be translated lies in the same XY plane as the UCS.
