2D CAD sketching software for engineers who build with precision.

Professional design tools shouldn’t be out of reach.

Pingendum is a CAD application being developed for 2D and 3D design. Its initial release is a precise 2D drafting environment — one that draws to exact dimensions rather than approximate ones — built for engineers, designers, students, makers and small manufacturers who need a more accessible way to turn ideas into real designs. 3D solid modelling is currently in development as the next stage.

The Pingendum 2D desktop application with stepped-bracket.pingdrw open: a bracket 160 long and 70 high that steps down to 40, with R10 corners, an R8 inside the step, two 12 diameter holes and an R7 slot — ten dimensions in all. Around it are the File to Help menu bar, the Draw and Modify tool palette down the left, the context bar above the canvas, the Layers and Properties panels on the right, Find a command on Ctrl+K, and a status bar carrying the Ortho, Polar, Grid, Snap and Track aids with the drawing and annotation scales and the cursor coordinates.

Why Pingendum exists

Good ideas shouldn’t stop at the price of the software needed to design them.

Pingendum began with a straightforward frustration: professional CAD tools can be expensive, particularly for people building independently or starting small.

Students may have access through educational programmes. Large companies can budget for professional software. But the gap can still be significant for the independent engineer, maker, small manufacturer, or person trying to turn an idea into something real.

Henrik Pryter started Pingendum after experiencing that barrier firsthand. The goal was simple: build precise design tools that are within reach of the people who need them.

Build the idea. Not the software bill.

Who it’s for

Built for people who build.

The common thread isn’t a job title. It’s needing a drawing to be exact without needing an enterprise CAD setup to get there.

  • Engineers

    For precise 2D geometry and technical sketches that need to hold their dimensions.

  • Designers

    For turning concepts into dimensioned designs that can be shared and built from.

  • Students

    For learning constraint-based design when educational access isn’t available or doesn’t fit.

  • Makers

    For designing parts that are going to be cut, printed, machined or built for real.

  • Small manufacturers

    For shops that need practical drawing tools without the cost structure of enterprise CAD.

  • Independent builders

    For people developing their own ideas without a large company or engineering team behind them.

What you can build

Real parts, drawn to size.

Pingendum is for the drawing you intend to make something from. Every feature below is both sized and located — enough to make the part from the drawing alone.

A stepped bracket drawn in Pingendum 2D: a closed profile 160 long and 70 high that steps down to 40 high at 110 along, with R10 rounded corners at the top left and at the step, and an R8 radius inside the step. Two 12 diameter holes and a slot with R7 ends are cut through it, each carrying a centre mark. Ten dimensions in all — 160, 110, 70 and 40 on the profile, two Ø12, two R10, an R8 and an R7.

Stepped bracketTen dimensions — 160 overall, 70 high, stepping down to 40 at 110, R10 corners and an R8 inside the step, two 12 mm holes and an R7 slot, drawn from typed coordinates and dimensioned from the geometry itself.

An angle bracket drawn in Pingendum 2D: a closed L-shaped profile 120 along the base and 90 up the upright, with a 20 wall on each leg and an R12 fillet at the inner corner where they meet. Four 9 diameter holes are drilled through: two in the base and two in the upright, each with a centre mark. Six dimensions in all — 120, 90, 20, R12 and two Ø9.

Geometry the sketcher is built for

  • Brackets and mounting plates

    Closed profiles with steps, notches and radii, dimensioned end to end so the shape is defined rather than approximated.

  • Hole patterns

    Mounting holes and bolt circles placed to dimension instead of by eye. The servo horn in the hero carries six of them at 2.00.

  • Slots and cutouts

    Straight slots drawn to a typed length and width, then trimmed into the surrounding profile.

  • Chamfered and filleted profiles

    Corner treatments applied in the sketch and carried by the solver. The bearing pedestal below closes with two 21.21 chamfers at 135 and 225 degrees.

  • Reference and construction geometry

    Driven dimensions that measure without over-constraining, and construction lines that guide without joining the profile.

  • Drawings you can hand on

    DXF for the next tool in the chain, or a plotted PDF sheet for someone who just needs to read it.

How it works

Precision you type, not precision you aim for.

  • Snap to the point you meant

    Object snaps hold the cursor to endpoints, midpoints, centres, intersections, perpendiculars and tangents, and a marker tells you which one you are about to take before you commit to it.

  • Type the geometry instead of aiming at it

    Give a length and an angle, or absolute and relative coordinates, straight at the cursor. Ortho, Polar and Track keep a line where you intended it rather than where the mouse landed.

  • Change it after you have drawn it

    Drag a grip to stretch, move or rotate what is already there, or type an exact value into the Properties panel. Select by Properties finds every object that matches and edits them in one go.

  • Hand the drawing on

    Export DXF for the next tool in the chain, or lay the drawing out on a sheet at a stated scale and plot it to paper or PDF for someone who just needs to read it.

Four holes selected together in Pingendum 2D, each showing its grips. The Properties panel on the right reports the selection as 4 Circles: Centre X and Centre Y read Varies because the holes are in different places, while Radius 4.50 and Diameter 9.00 are shared and can be changed for all four in one edit.

Pingendum in action

Everything the sketch needs. Nothing it doesn’t.

Three captures of the application on real drawings — getting the geometry right, repeating what repeats, and getting the drawing out.

01

Draw it where you meant it.

Object snaps hold the cursor to the endpoint, midpoint, centre or intersection you are aiming at, and a marker names the one you are about to take. Ortho and Polar lock a line to the angle you want, Track runs guides out from points you have already used, and anything you would rather state than aim at can be typed — a length and an angle, or a coordinate — straight at the cursor.

A line being drawn across the stepped bracket in Pingendum 2D. The cursor has locked onto the bottom-left corner of the profile: a square Endpoint marker sits on it with the word Endpoint beside it, and the line being drawn reports its length, 100.12, and its angle, 163.68 degrees, in two fields at the cursor. The context bar above reads "Line · Next point" followed by the forms it will take typed instead — x,y, @dx,dy, @length<angle, or a distance. Along the status bar below are the Ortho, Polar, Grid, Snap and Track aids, with Polar and Snap switched on.

02

Hatch it, and draw repeated parts once.

Click inside an outline and Hatch fills it, leaving holes clear and following the outline if you edit it. Anything you draw more than once becomes a block: make it once, place it wherever it goes, and every placement changes when you redefine it.

The same dimensioned angle bracket, now filled with ANSI31 45-degree section hatching that leaves all four holes clear. A hexagonal bolt head sits over each hole — four placements of one block, Bolt M8, made once and inserted four times.

03

Finish it on a sheet, and hand it on.

Model space holds the part at full size. A sheet holds the drawing of it: place a viewport, set the scale it is viewed at, and add the border, the title block and the notes in paper millimetres, where they stay the size you drew them whatever the scale. Plot the sheet to paper or PDF, or export DXF for the next tool in the chain.

Sheet 1 of the stepped-bracket drawing in Pingendum 2D: a white page with its printable border drawn in, and the dimensioned bracket showing through a viewport set to 1:1. The Model and Sheet 1 tabs sit below the page, and the status bar carries the drawing aids and the 1:1 scale.

How it behaves
PRECISIONObject snaps
Ten snap modes — endpoint, midpoint, centre, quadrant, node, insertion, intersection, perpendicular, tangent and nearest — with the everyday seven on by default and a marker naming the one you are about to take.
INPUTDrafting aids
Ortho holds a line to the axes, Polar to a chosen angle increment, and Track runs guides out from points you have already snapped to. Grid snap steps the cursor by a set increment when you want it.
INPUTTyped coordinates & values
Give a length and an angle, or absolute and relative coordinates, straight at the cursor, and type an exact value into any field in the Properties panel afterwards.
TOOLSReference geometry
Construction lines that guide without becoming part of the profile, centre marks and centrelines on holes, and dimensions that measure the geometry wherever you need it stated.
Scope

A focused first release.

Pingendum is a CAD application for 2D and 3D design. The 2D drafting environment is the part that is finished, so it is the part being released first.

Available in the 2D sketcher

2D parametric sketchingIn this release

Geometry, the full constraint toolkit, degree-of-freedom feedback, diagnostics, grid snap, drafting aids and reference dimensions.

Not in the first release

Solid modellingIn development

Pad, pocket, revolve, fillet, chamfer, shell and patterns are already built. They are not what this first release is for, and will arrive in a later build with the documentation that covers them.

File formatsDXF and PDF

Projects save to Pingendum’s own versioned format. Drawings import and export as DXF — R12 or R2000, geometry on layer 0 and construction geometry on its own layer — though dimensions and constraints are not carried across, because DXF has no way to represent them. Drawings also plot to a PDF sheet or a printer at a real scale, with an ISO title block and hidden, frozen and non-plot layers left off the paper. There is no DWG, STEP or STL export.

Simulation and renderingNot scheduled

On the long-term roadmap only. Neither is promised for a date, and neither is being sold to you today.

Work beyond the sketcher is tracked in the changelog as it lands, and the documentation covers the sketcher chapter by chapter.
