Abarca services
Free tools for the tradesTools for the trades
Mark up drawings. Run takeoffs. Track your time.
Abarca builds free, browser-based tools for people who build — a PDF markup and takeoff app, a work-time tracker, and a trig field calculator for conduit bends. One file each, no installs, no accounts, and your drawings never leave your machine.
The apps.
Three tools, built by a tradesman for the trades. Each one is a single file that runs entirely in your browser — no installs, no accounts, no uploads. Your drawings and your data never leave your machine.
Abarca markup.
A PDF markup and takeoff tool built for the trade — measure, count, compare revisions, and search symbols across a whole set. One file, no installs, no accounts. It runs entirely in your browser and your drawings never leave your machine.
Measure & count
Markup tools.
Pen, lines, arrows, polylines, shapes, highlights, and text, plus revision clouds, polygons, callouts, and Approved/Void stamps — color, weight, and opacity on every one.
Scaled measurement.
Set the scale once, then dimension, run poly-lengths, measure areas, or gauge diameters — imperial or metric, in your units.
Count & takeoff.
Counts, lengths, and areas total live across the set in a filterable, sortable spreadsheet — edit, bulk-delete, or reassign layers right from the list.
Parts & assemblies.
Save assemblies over a parts catalog — place 40 devices, get 40 boxes, rings, straps, and screws on the takeoff. Import and export by CSV.
Search & compare
Symbol search.
Box one symbol and find every match across the set — rotation-aware, with a sensitivity slider and thumbnails. Turn the hits into a count in one click.
Text search.
Find any text on this sheet or across every sheet — accent-insensitive, with jump-to-match highlights on the drawing.
Revision compare.
Overlay an old revision in red and blue to see exactly what moved, with an adjustable offset to line the two up.
Text compare.
Diff two revisions' text and step through every addition, edit, and deletion — catch spec and keynote changes a visual scan would miss.
Organize & deliver
Layers, sets & legends.
Layer markups, group sheets into sets, auto-label from the title block, and drop live legends. Hide a layer and it leaves the drawing but stays in the takeoff.
Snap, grid & text select.
Snap to linework, vertices, or a scaled grid with a live lock indicator — and drag across sheet text to copy schedules and keynotes, no retyping.
Vector export.
Markups export as true vectors — sharp, searchable, not a screenshot. Pick which sheets go out; hidden layers stay off the deliverable.
Fillable forms.
Drop text boxes and checkboxes onto a drawing and export a real fillable PDF — inspection reports and sign-off sheets anyone can complete in Acrobat or a browser.
Spreadsheet export.
Send the takeoff to CSV or a formatted XLSX — summary totals and a full itemized list, ready for your estimate or material order.
Local-first: your work lives in this browser. Use Back up / Restore (in the app menu) to move between machines.
Abarca time.
Project time tracking with the same rules as markup — one file, runs in your browser, your records stay on your machine.
Track by project.
Start a timer or log entries by hand, organized per project — with a running total right in the browser tab.
Clockify in & out.
Import and export Clockify-format CSV, so existing records come with you and reports drop into whatever you already use.
Local-first.
No accounts, no sync service, no installs. Back up to a single JSON file and restore it on any machine.
Abarca trig.
A trig field calculator for electricians — solve triangles, lay out conduit offsets and saddles, and convert units, with every answer drawn to scale and every step shown.
Any triangle.
Right triangles from any two knowns, plus SSS, SAS, ASA, AAS and the two-answer SSA case — drawn to scale with the worked steps.
Conduit bends.
Offsets, rolling offsets, 3- and 4-bend saddles with bend marks and shrink, plus a full multiplier and shrink table.
Field-friendly.
Type fractions like 3 1/2, get answers to the nearest 1/16″. Arcs, radius from chord and sagitta, and angle and length conversions.
Learn markup.
Short, practical guides — each one takes you from a blank sheet to a finished deliverable. The full user guide covers both apps end to end.
Set a sheet scale
Pick a known scale from the toolbar, or calibrate against a dimension printed on the sheet. Every measurement on that sheet follows from it.
Run a takeoff
Measure lengths and areas with subjects like “2″ EMT”, place counts for devices, then open the Σ Takeoff tab for live totals and CSV export.
Build a count tool with parts
In the Toolbox tab, create a tool with a symbol, subject, and the parts each placement represents. Arm it, click your way across the sheet, and the parts rollup does the material list for you.
Export for the GC
Export writes your markups as vectors into a copy of the original PDF — dimensions, notes, and count numbers all searchable. Hidden layers stay out of the deliverable.
BIM services
Abarca also takes on select electrical BIM work — coordination, installation documents for the field, prefab support, and pre-BIM markups and takeoffs.
Electrical BIM coordination.
Full-cycle coordination of the electrical scope in Revit — modeling raceway, equipment, and supports, running clash detection against every other trade, representing electrical in coordination meetings, and carrying the model through to sign-off.
Field installation documents.
Installation-ready deliverables built from the coordinated model — dimensioned layouts, hanger and rack details, sleeve and penetration drawings, and equipment room plans. Drawings the field can build from without guessing, backed by the coordination behind them.
Prefab support.
Spool sheets, assembly details, and cut lists pulled from the coordinated model so the shop can build ahead of the field — with the layout data and quantities the prefab team needs to keep production moving.
Pre-BIM markups & takeoffs.
The step between estimating and modeling: drawing-set review, document markups, and quantity takeoffs for tracking material, layout data, and installation workflows — built to support superintendents and project managers day to day.
Behind Abarca.
Abarca Services is run by Shane — a master electrician and IBEW member with 25 years in the trade, working across BIM coordination, detailing, and application development for the field. Every model, drawing, spreadsheet, and app comes from someone who understands how the work actually gets installed.
