What it calculates

Every calculation has its own screen, with its drawing.

The figure to cut or to mark stays at the top of the screen while the values are typed in. Below it come the dimensioned drawing, generated by code from the result, and the intermediate values.

The drawings below are parts of real screens from version 2.0, in development.

Pipework

The pipe to cut between two fittings, with the take-off of each one already deducted. Elbows cut to any angle, rolled elbows, S jogs, manifolds and branches on an elbow, and an estimate of the welding consumables.

  • Cut length
  • Cut an elbow
  • Rolled elbow
  • S jog
  • Manifold
  • Branch on elbow

Offsets

Offsets made with standard elbows cut to the angle the job needs. GeoMont gives the elbow angle, the nipple between the two elbows and the arcs to mark along the back and the throat, with a 2D drawing and, in most tabs, a 3D view.

  • S-offset with two cut elbows
  • Corner with two elbows

Branches and cut-outs

Pipe to pipe, pipe to elbow, elbow to pipe and tee with elbow. Elevation and section drawings, the developed template of the branch and of the hole, a table of ordinates to mark the cut without a printer, and a printable template at 1:1 scale.

Bending

Offsets, rolling offsets, three- and four-bend saddles, 90° bends and large radii. The distance between bends, the shrink and where each mark goes on the tube.

  • Offset
  • Rolling
  • Saddle 3
  • Saddle 4

Tables and weights

Pipe, fitting and flange tables to EN/DIN and ASME, bolt data, and the weight of pipes, profiles, tubes and solid bars. Also bolt torque with the tightening order, bolt-circle marking, support spacing and thermal expansion.

These are five real frames of one tab, Sheet metal · Elbow: the same 90° elbow made with two, three, four, five and six segments.

Each time, the calculation engine works the figures out again and the drawing is generated from them. The drawing is not a stored picture: the code draws it.

In 3D

A 3D view that turns under the finger.

Real frames from the 3D viewer of the app, in Pipework · Rolled elbow: one full turn, one frame every 10°.

The dimensions move with the piece so that they can be read from any side. Tapping an edge of the box lets you type its measurement.

The 3D view of GeoMont in “Pipework · Rolled elbow”: a pipe between two 45° elbows inside a box, with the rise, the roll and the length of the pipe dimensioned. On the page it turns a full circle.

How it is built

GeoMont is made by one independent developer, working alone and self-funded.

It is built with Claude Code.

Planned for version 2.0 · not working yet

  • Using Claude to recognise piping symbols in a photo.
  • Using Claude to turn an isometric drawing into a parts list.

The model only identifies and fills in fields. The user confirms, and the tested engine does the math.
