Short description

🧩 DynamicDivide is an AutoCAD AutoLISP utility that dynamically divides a LINE ARC or LWPOLYLINE into equal segments using POINT entities.
👁️ Moving the cursor over a supported object displays temporary division points before the user commits the operation.
⌨️ The number of divisions can be changed interactively with plus and minus keys or entered directly from the keyboard.

Command:

Main command: DynamicDivide

Description:

📐 The routine calculates the total curve length and divides it by the selected segment count.
👁️ Mouse movement uses temporary grpoint graphics so the user can preview the division points before clicking.
📍 A mouse click on a supported curve creates permanent AutoCAD POINT entities at the calculated intermediate distances.
➕ The plus key increases the segment count while the minus key decreases it with a minimum practical value of two.
🔢 A new segment count can also be typed and accepted with Enter or Space.
💾 The last segment count is stored through setenv under dexus:DynamicDivide and reused on the next run.
🎨 Temporary point graphics follow the current PDMODE PDSIZE and current layer color behavior.

Helper function: (if any)

vlax-curve-getDistAtParam calculates total curve length.
vlax-curve-getPointAtDist calculates every division location.
grpoint draws temporary markers using the current AutoCAD point display style.
setenv stores the last selected DynamicDivide segment count.

Functionalities:

✅ Dynamic preview – shows temporary point markers while the cursor moves over supported geometry.
✅ Equal segment division – calculates equally spaced locations from total curve length.
✅ LINE support – divides straight line entities.
✅ ARC support – divides arc entities by curve distance.
✅ LWPOLYLINE support – divides lightweight polylines by accumulated curve length.
✅ Keyboard count control – supports plus minus and direct numeric entry.
✅ Persistent count – remembers the last segment count between command runs.
✅ Point style integration – temporary markers respect AutoCAD point display settings.
✅ Undo grouping – wraps generated point creation in an AutoCAD undo group.

Result:

🎯 The result is a set of AutoCAD POINT entities positioned at equal intervals along the selected curve.
📏 The source curve remains unchanged.
