AutoLISP Routines

LAYERPILOT watches every command you start and silently switches the current layer to whichever layer that command’s output belongs on. Start TEXT and you land on the TEXT layer; start DIMLINEAR and you land on DIMENSIONS; finish the command and your original layer comes straight back. What LayerPilot does You never touch the layer dropdown again, and … [Read more...] about LAYERPILOT LISP: Automatic Layer Switching by Command

LAYERHARVEST points at a folder, reads every drawing in it, and writes out the complete layer table of each one: name, colour, linetype, lineweight, plot flag, plot style, on, locked, frozen, frozen in new viewports, and description. No drawing is opened in the editor. What LayerHarvest does This is the tool for auditing a drawing set against a layer standard. Run … [Read more...] about LAYERHARVEST LISP: Audit Layers Across a Folder of DWGs

HIDESECTION breaks an object at two points and puts the middle section on a hidden layer, showing concealed detail in one operation. Done by hand this is genuinely tedious: break the object twice, hunt for the middle fragment, select it, change its properties. What HideSection does Worse, a circle or full ellipse cannot be broken at a single point at all, so the … [Read more...] about HIDESECTION LISP: Break an Object and Hide the Middle

HATCHCLEAR clears hatching from behind text so buried annotation becomes readable again. Select the text and the offending hatch, and the hatch gains a new island boundary around each piece of text — genuinely cutting the pattern away rather than masking it, so it stays correct when plotted. What HatchClear does It also reaches text inside blocks, including … [Read more...] about HATCHCLEAR LISP: Clear Hatch From Behind Text in AutoCAD

GRIDSURF reads a CSV of gridded levels and builds either a 3D mesh or a cloud of 3D points from it. It is aimed at survey and site data, where the levels arrive as a regular grid and getting them into the drawing is the tedious part. What GridSurface does The expected file format is a plain rectangular grid of Z values — nothing else. Each line is one row of … [Read more...] about GRIDSURF LISP: Import a CSV Grid as a Mesh or 3D Points

PINOBJECT pins individual objects so they cannot be modified, and keeps them pinned between drawing sessions. Three commands: PINOBJECT pins a selection, UNPINOBJECT releases one, UNPINALL releases everything and removes the stored record. What FreezeFrame does Read this before relying on it. This is a demonstration of what reactors can do, not a security feature. … [Read more...] about PINOBJECT LISP: Pin Objects Against Accidental Edits
