Reliable, Easy to Use Design Software

From PDF to analysis model, in minutes.

Burning hours building your analysis models from PDF markups? SkyCiv Markup will extract your walls, beams, columns and slabs to scale – aligning all your pages to gridlines to ensure accurate model generation.

How it works

PDF annotations to analysis, in 3 steps…

Upload and annotate your PDF drawings to scale

Upload your PDFs, we’ll automatically detect your existing annotations. You can even SkyCiv Markup to annotate additional elements.

Aligns your sheets and detects structural elements

We’ll read your annotations and turn them into a scaled, accurate structural analysis model. The model will be aligned to gridlines for accuracy and reliability

Export to your preferred structural analysis products

SkyCiv markup will generate an accurate analysis model, which can be exported to ETABS, STAAD, SkyCiv, SPACEGASS and 2D/3D DXF for general importing.

core features

A unique workflow, completely integrated and seamless

Save time going from PDF – Analysis and reduce re-work by quickly iterating your designs

Overview

  • Set your scale, we’ll also attempt to automatically extract this information
  • Set your datum – this will align your sheets to ensure your building is built accurately

  • Define your elevations – which will be used to generate the floors in your structural analysis model

  • Users can also run a test-analysis to ensure the model returns accurate dead-load cases before exporting

  • Changes come through? Simply swap out your PDFs with the updated document, and adjust your annotations to match

Annotating software, built for structural engineers

SkyCiv Markup allows engineers to quickly markup architectural drawings with these easy built-in features.

  • Automatically detects existing annotations, or add your own

  • Use built-in lines, polygons, polylines, revision clouds, call outs, rectangles for your structural elements

  • All your favourite shortcuts

  • Snaps to gridlines to ensure your structure is aligned and accurate

  • Import section outlines to scale, from our library of over 25,000 sections

Apply loads for faster designs

Since you’ve already marked your columns, walls and slabs – we can use that information to perform a load takedown. This is independent of our FEA solver, so the results offer an independent review of your load paths.

Apply loads to your beams, tributary areas will automatically be calculated and used in your analysis model.

All design modules feature detailed calculation reports – no more black boxes!

Build your structural engineering models in minutes

Once defined, your annotations will be turned into columns, beams, walls and slabs to generate an accurate and solve-ready structural analysis model.

  • Run tests to ensure your structure is built correctly, with no connectivity issues

  • Elements snapped to grid and each other for accurate model generation

  • Define supports automatically

  • Sheets are aligned to a common datum to ensure floors are aligned

Integrates with your existing workflows

Don’t re-invent the wheel; just save time in your existing design flows.

  • Import PDFs that are already annotated – we’ll automatically detect them

  • Import a fresh PDF and start annotating using built-in tools

  • Export to analysis products: STAAD, ETABS, Spacegass

  • Export to PDF as a flat PDF

  • Export to Structural 3D – meshed and ready to solve

No need to re-invent your workflow – go from PDF to your favourite analysis products, in minutes.

    Trusted by thousands

    The ease of use and the presentation of the results are both awesome. I have had ongoing interaction with the support team and everyone is excellent.

    It is used for various civil and mechanical engineering courses and the students love it. We are happy with the continuous updates to SkyCiv as well, highly recommended.

    It was easily the most intuitive package available to learn; it is particularly easy to build the 3D model and define nodes, members, supports, materials, sections, then apply loads & combinations.
