If you are an AutoCAD or Civil 3D professional, you already know the pain of manually calculating the total lengths of lines, polylines, and pipe networks. Tallying up these measurements, grouping them by layer, and transferring the data into a formatted Excel spreadsheet or AutoCAD table can eat up hours of your workday.
Enter INAR Total Length Studio—a premium, fully automated AutoLISP utility designed to revolutionize how you calculate, categorize, and report geometric lengths in your drawings.
What is INAR Total Length Studio?
INAR Total Length Studio is an advanced AutoLISP script engineered specifically for AutoCAD and Civil 3D environments. It goes far beyond basic length calculators. This tool intelligently scans your drawing, calculates the exact lengths of LINE, LWPOLYLINE, and POLYLINE objects, categorizes the totals by Layer, and instantly generates professional, presentation-ready outputs.
Whether you are estimating pipe networks, calculating road centerlines, or tallying electrical conduits, this AutoCAD automation tool delivers pinpoint accuracy and stunning visual reports in seconds.
🌟 Key Features of INAR Total Length Studio
1. Smart Layer Categorization
Stop copying and pasting layer names into spreadsheets. The script automatically extracts the layer information from your selected objects and groups the total lengths accordingly. The results are neatly sorted alphabetically for easy reading.
2. Professional AutoCAD Table Generation
Need a summary table directly inside your drawing? INAR Total Length Studio features a highly customizable CAD Table Generator. You can control:
- Text Style and Text Height
- Cell Width and Cell Height
- Text Alignment (9 different alignment options)
- Overall Table Scale
3. Premium Excel Export with Data Visualization (.xlsx)
This is where the tool truly shines. Instead of exporting a plain CSV file, INAR Total Length Studio uses native COM automation to build a highly styled, professional Excel workbook.
- Custom Typography & Layout: Features modern fonts (Segoe UI), color-coded headers, and hidden gridlines for a clean dashboard look.
- Automated Formulas: Includes a dynamic
SUMformula for the Grand Total. - Auto-Generated Doughnut Chart: Automatically generates a modern, beautifully styled Doughnut Chart showing the percentage distribution of lengths by layer.
4. Interactive DCL Dashboard
No need to memorize complex command-line prompts. The tool launches a sleek, interactive Dialog Control Language (DCL) dashboard, allowing you to configure your table properties and toggle your desired outputs (CAD Table, Excel Export, or both) with a simple click.
