✂ Section view
Planes above are the default cut. Or just CLICK any hole / round wall in the model — the section goes through it directly.
⏲ Quick Slide
Pick the faces a slide must form — it builds the slide as
ONE solid off that geometry (like Quick Electrode), with the heel at your angle, the angle-pin bore and
the gib rails. When the mold base is built, the plates get the pocket cut for slide, rails and stroke.
— select the moulded part —
No forming zone yet.
🧩 Build Faces
Click faces on the part to copy them off. Openings ringed by a
planar face are patched shut — the shutoff patch. If the collection knits CLOSED it becomes a solid part;
an open shell is kept as a surface part and says so, never silently solidified.
Picked: 0 face(s)
▧ Finish & texture spec
Click the faces this finish applies to, then apply. The VDI 3400 grade
fixes the Ra and the minimum draft the texture demands — and the draft of every specified face is
then MEASURED against it.
Picked: 0 face(s) · pull Z+
⚯ 3D sketch
Click points on the model — the ray gives the point ON the surface,
so it is as exact as where you clicked. For an exact point, type X Y Z below instead. The chain saves with the
document and can be swept round into a solid.
No points yet.
⤒ Offset Surface
Click faces on the part; each is offset along its own normal by the
distance below into a SURFACE part. A plane translates; a cylindrical face changes radius. The measured
area of the result is reported — nothing is assumed.
Picked: 0 face(s)
⚠ Interference check
Every visible pair of parts, checked with the kernel's own
boolean — not the boxes. Slides in their pockets, pins in their bores, inserts in their plates: all of it
should overlap NOTHING. Touching faces are not clashes. Click a result to light the pair up red.
📌 Ejection editor
The automatic layout places a sensible grid — this is where YOU
put pins under the ribs and bosses it cannot know about. Click the core where a pin should stand: the tip
lands on the moulding surface, the DIN 1530 head is pocketed in the ejector retainer, the support and
B plates get their clearance bores and the core its fit bore. ✕ removes an added pin, cuts and all.
🎲 Runner designer
Lay the feed by hand: click the runner centreline waypoints on the
parting plane (sprue end first, gate end last). It builds the full-round runner as its own part — the
waste is a number — cuts each plate's half of the groove exactly, drops cold slug wells at the free ends and
puts an edge-gate land on the last segment.
🧭 Quick Lifter
An INTERNAL undercut that cannot slide sideways is formed by a
lifter: a leaning blade that travels with ejection — going up, the nose also moves sideways and pulls
its boss out of the groove. Pick the undercut faces; it builds nose + blade as one solid and cuts the angled
plate pockets when the base is built.
— select the moulded part —
No undercut picked yet.
🛠 Creative Build
Put a part — a slide body, say — in the working direction
of the moulded part: pick the part, then the base face its bottom sits over. It lands centred with a gap,
slides freely along that axis, and Interactive Cut carves the moulding's exact geometry into it right
where you put it — no Remove Face afterwards. The formed faces are listed; drop any and the cut
rebuilds without it.
Pick the part to place, then its base face.
0 = touching the base face · negative = plunged INTO the part, ready to cut
⚡ Quick Electrode
An electrode with a rectangular base, for milling —
the Cimatron Quick Electrode way of working, step for step. Pick the steel, say which way the
electrode comes in, click the faces to erode, and it builds the burn body, the extension and the
blank as one solid with the orientation chamfer on it.
— select a part —
No frame yet.
The gap is your machine's, not a formula — this app does not
guess it. Left at 0 the electrode is nominal and says so on its drawing.

📡 Sensors —
Watch a measurement and get a warning the moment a design change pushes it out of range.
🅰 Annotations —
Notes that travel with the part — tolerances, heat treatment, supplier, anything the shop needs. They export into the drawing title block.
📋 Bill of Materials
📝 ECO — engineering change log
Each change is journalled with its date, the affected parts’ measured volume and weight at that moment, and a viewport snapshot. Numbers are never reused; the log saves inside the document file.
✅ Design review — the pre-steel checklist
✂ Split insert
Draw open line(s) or polyline(s) in a sketch first — each must cross the WHOLE part. The kernel splits the solid along walls extruded from those lines; every region becomes its own piece part, filed in a folder, material inherited. Pocket a piece back with Indent / cut with part.
❋ Radial Component Pattern
Repeats the component around an axis through the centre you give. A full 360° spaces N copies at 360/N; a partial angle spreads them over it.
Centre A/B are the two axes crossing the pattern axis: Z → (X, Y) · X → (Y, Z) · Y → (Z, X).
⚖ Mass rollup
Kernel-measured volume per part; weight only where the part carries a real density — a part at “—” is listed but never guessed.
⋮⋮ Linear Component Pattern
Repeat the selected component along a direction — the copies keep the original's mates to the fixed part.
🌪 Injection simulation
💧 Cooling circuit
Cross-drills a real circuit into the plate you pick, with the end connectors, blanking plugs and nipples that make it a circuit rather than a row of holes.

🧲 Mold Design Tool
Premium
⚙ Parameters — draft, clearance, pin & lifter angles
Attach a STEP or a ProvenCad part, and it works out what the
tool has to be — and why. Classification rules from Gastrow, Injection Molds — 130 Proven
Designs; every millimetre from this part’s own geometry.
Fit checks:
▣ Build the forming components
closed
The side actions run out along their own escape first —
that is what an angle pin does in the first millimetres of opening — and only then do the
halves part. If a slide is going to foul the moulding, this is where you see it.
▤ Step 2 — the mould base
The plate size is the smallest catalogued one the insert
array fits in, the thicknesses come off the insert depths, and every plate is machined for the real
steel in it — the insert blocks and every slide or lifter over its whole stroke.
No article number is invented: a reference this app has not verified against the manufacturer’s
own sheet is printed with a “?”, and anything with no reference is named by what it is.
Each part of the base can be set to Auto — it then compares the standards this app has
real catalogue numbers for and keeps whichever gives the tighter, more precise fit — or forced
to one standard by hand, so a Meusburger plate stack can carry HASCO guide pillars if that is what
fits best.
