Picking & storing bookmarks: • Button “Pick from drawing” calls bm-pick-and-store which:   – Uses ssget with filter (0 . "TEXT,MTEXT,LINE,LWPOLYLINE,POLYLINE,CIRCLE,SPLINE,INSERT").   – For each entity, determines:     • Label – e.g. “TEXT”, “LWPOLYLINE (closed)”, “3D POLYLINE”, “BLOCK MyBlock”.     • Representative start/end points via bounding box or geometry.     • Color string via bm-color-string (TrueColor/aci/ByLayer/ByBlock).     • Handle and entity type.   – Creates an entry with empty remark "" and appends it to *bm-list*.
Group / filter system: • bm-entry-group maps entity type to a group name:   – TEXT/MTEXT → “Text”.   – LINE → “Lines”.   – (LW)POLYLINE → “Polylines”.   – CIRCLE → “Circles”.   – SPLINE → “Splines”.   – INSERT → “Blocks”.   – Others → “Other”. • bm-build-groups scans *bm-list* and builds *bm-groups* = ("All" ... unique group names ...). • The popup “Group” in the dialog is filled from *bm-groups*; changing it updates *bm-group* and refreshes the list. • bm-pass-filter ensures only entries matching the selected group (or All) are shown.
Dialog listboxes & synchronization: • Columns are separate list boxes:   – No / Element (lb_elem) – row number + label.   – Coordinates (lb_coord) – bookmark start point as “X,Y,Z” (formatted using current LUPREC).   – Color (lb_color).   – Remark (lb_rem). • bm-update-list rebuilds these four list boxes from *bm-list* + current group filter, and rebuilds *bm-index-map* for “visible index → real index” translation. • Selecting in any of the list boxes forces all other list boxes to the same index and runs bm-on-select (which updates the Remark edit box).
Zoom to bookmark: • Button “Zoom” calls bm-apply-zoom:   – Uses selected row in lb_elem to get visible index, then real index via *bm-index-map*, then fetches entry from *bm-list*.   – Attempts to resolve the current entity by handle using handent. If found, recomputes the bounding box for an up-to-date zoom window (even if the object has moved). If not found, falls back to stored start/end points.   – bm-make-window builds a padded window around those two points (5% margin).   – Calls bm-zoom-ll-ur, which uses vla-ZoomWindow to actually zoom the current view.
Remarks: • The edit box “Remark” lets you attach a free-text comment to the selected bookmark. • bm-update-remark-field fills the edit box when you change selection. • Button “Set” calls bm-set-remark which:   – Reads the current remark text.   – Updates the corresponding entry in *bm-list* (using bm-replace-nth).   – Rebuilds the lists and re-selects the same visible row so the UI stays in sync.
Duplicate / Delete / Clear: • Duplicate – inserts a copy of the selected entry immediately after it in *bm-list* via bm-insert-after-nth, then refreshes the UI. • Delete – removes the selected entry from *bm-list* via bm-remove-nth and clears the remark field. • Clear – empties *bm-list* and *bm-index-map* in one shot and refreshes all list boxes.
Save / Load / Import (per-DWG persistence): • Automatic default file path: DWGPREFIX + (vl-filename-base DWGNAME) + "_BMEntityPos.lst".   – This means each drawing can have its own bookmark list stored right next to the DWG (same prefix, custom suffix). • Save – bm-save-list:   – Writes *bm-list* as a single LISP-readable expression into the default file (using prin1).   – Notifies with the path on success; warns if there’s nothing to save. • Load – bm-load-list:   – Reads from the default per-DWG file, validates that it’s a list, assigns it to *bm-list*, and updates the dialog. • Import – bm-import-list:   – Uses getfiled to let you choose any .lst file containing a bookmark list.   – On success, replaces current *bm-list* with the imported content and updates the dialog, with a path confirmation message.

Key functionalities of slope_p: • Dual input modes: 2-point mode or entity-selection mode, switchable in the dialog. • Flexible slope formats: Percentage, per-mille, H:V ratio (x.xx:1), or V:H ratio (1:x.xx). • Optional angle label: Can show angle in Degrees, DMS, Grads, or Radians; may be combined on a second line under the slope. • Prefix / Suffix control: Independent prefix/suffix strings for slope and angle text (e.g., “S=” or “α=” etc.). • Scaling & offset: User-set text height, horizontal/vertical scale factors (to respect vertical exaggeration), and above/below toggle for label offset from the line. • Drawing units integration: Dialog can read and set LUNITS, AUNITS, LIGHTINGUNITS, and their precisions for consistent numeric formatting. • Segment-wise labeling: For polylines, every segment is processed individually with its own midpoint and orientation. • Robust checks: Skips zero-length segments, handles vertical slopes (INF) and guards against invalid numeric inputs.

• Slope formatting options — Percent, integer ratios, or decimal ratios • Scale-aware slope calculation — Applies H/V multipliers before evaluating run & rise • Negative slope detection — Prepends “-” when dy indicates descending elevation • Robust ratio reduction — Converts values like 200:100 into 2:1 cleanly • Special case protections — Vertical/horizontal slopes produce INF-safe labels • Controlled text placement — Aligns TEXT with segment and offsets above/below automatically • System variable safety — Temporarily sets and restores OSMODE and LUPREC • Dialog-driven settings — Radio buttons ensure mutually exclusive format choices

• Entity filtering Skips unsupported types and informs the user • Count enforcement Ensures exactly two valid entities; warns if fewer or more • Automatic opening of polylines Closed LWPOLYLINE is forced open with a status message • Endpoint connection Creates LINE from start-to-start and end-to-end via ENTMAKEX • Automatic joining Uses PEDIT multiple and join to merge all entities into one polyline • Failure handling Gracefully aborts with a message if selection invalid or empty

• • Runtime DCL generation creates and deletes a temporary dialog file automatically.
• • Layout list shows available paper-space layouts and excludes Model from duplication choices.
• • Per-layout copy counts lets the user assign different copy quantities per selected layout using the Set Count workflow.
• • Summary management displays the configured list of layouts and counts and allows removal via Delete prior to running copies.
• • Automated naming generates new layout names by appending a two-digit sequence suffix to the source layout name.
• • Command-based duplication performs duplication using ._layout _copy for each requested copy instance.

• Two main modes: Supports separate Planum and Gelaende workflows that share the same configuration dialog but use different layers, styles, and offsets for drawn labels. • Persistent configuration: Saves and reloads mode, reference level, scale, offsets, layers, styles, and edit flags so that each drawing remembers its last annotation settings automatically. • Interactive geometry picking: Asks the user to pick the intersection between center line and band, then finds cartridge and profile reference lines and repeatedly prompts for quotation points along the profile to place labels. • Automatic layer creation: Ensures all required Planum and Gelaende layers exist before drawing, and temporarily uses auxiliary layers for highlighting while restoring their colors after finishing. • Leader and label generation: For each picked quotation point it creates a vertical leader line from the point to the band, and places one distance text and one elevation text at configurable offsets below the band on their dedicated layers and styles. • Scale aware values: Converts drawing distances to real world distances using the configured drawing scale, and adds the reference elevation to the vertical difference to compute absolute heights. • Style enable options: Allows disabling or enabling layer and style dropdowns for Planum and Gelaende groups, which can lock them to configuration values or let the user freely choose from layer and style lists. • Context sensitive help: Multiple Help buttons open image files or a sample DWG showing what each parameter, layer, style, or mode represents, assisting the user in configuring complex settings. • Undo friendly: When undo is enabled, wraps the geometry operations into an undo group so the created labels and temporary changes can be reverted in a single step if needed.

Main Functionalities: • Turns off and re-enables the Navigation Cube display automatically. • Uses vla-sendcommand instead of manual user input, allowing programmatic control from scripts or macros. • Provides a quick way to refresh the ViewCube when it becomes unresponsive or missing. • Compatible with AutoCAD 2010+ versions supporting NAVVCUBEDISPLAY command.
