Glass
Glazing and mirrors: panels with their edge work, holes, notches and corners, for cutting tables and water-jets. A drawing whose industry is Glass offers these tools in the toolbar and in Edit › Tool.
Tools
| Tool | Does | |
|---|---|---|
| Edge Allowance | A panel's cutting size: its finished outline oversize by the edge work's allowance (or undersize) | |
| Fitting Notch | A hinge, clamp or patch-fitting notch in an edge, its inner corners rounded | |
| Corners | A panel's corners rounded, clipped (dubbed) or notched | |
| Hole Pattern | Holes measured from an edge (a row or grid), or round a centre | |
| Cut-Out | A socket or switch cut-out set back from an edge | |
| Water-Jet Inlay | An inlay's piece and its opening, with a fit clearance | |
| Lead | A water-jet's lead-in and lead-out, off the part | |
| Room Outline | A room (or a wall) from its lengths and turns |
Holes near edges
Toughened glass can't be cut or drilled after it is toughened, and a hole too near an edge or a corner breaks it. File › Check Design (and every machine export) checks holes in a Glass or Stone and tile drawing with the design rule Holes too near glass and stone edges, with the distances EN 12150-1 sets for toughened glass, measured from the hole's edge (a round hole's, or a slot's: two half circles joined by straight sides, drawn as one polyline or as lines and arcs):
- at least twice the thickness (T, or 6 mm if the drawing hasn't it) from an edge: the panel's, a notch's (made with the Fitting Notch or Corners tool, or drawn) or a cut-out's;
- at least twice the thickness from the next hole's edge;
- at least six times the thickness from a corner: the panel's, or a notch's or cut-out's inner corner. A rounded corner is measured from where its sides would meet, as if it were sharp; a U notch's round end has no corner;
- and a hole at least as big across (a slot: as wide) as the panel is thick.
A second rule, Sharp inner corners in glass and stone, checks the inner corners of notches and cut-outs (and of the panel itself, as in an L shape): a sharp one would crack, so each must be rounded to at least the glass's thickness and at least 10 mm (0.375 in) - glass processors ask for the thickness, and from 9 mm to 1/2 in. Arcs and a polyline's bulges count as rounded corners; a U notch's round end is checked too.
The panel can be one closed outline or lines and arcs meeting end to end, and notches and cut-outs made with the tools (blocks) are checked as well. See Design rules.
Notches and cut-outs
EN 12150-1 leaves the limits for notches and cut-outs in toughened glass to the processor. Two more rules check what toughening plants commonly ask for (for example the factory standards to EN 12150-1 of glass processors, and the guidelines for toughened glass that UK processors publish):
- Notches too big in glass: a notch in the panel's outline - in an edge, or a corner cut away - may be at most a third of the panel's width across and a third of its height deep. The notch is measured over its box, from the panel's sides; a rounded outer corner isn't a notch.
- Cut-outs too near glass and stone edges: the glass between a cut-out (a closed shape inside the panel that isn't a round hole or a slot: a socket's or a lock's) and the panel's edges must be at least half the cut-out's width to its left and right, and half its height above and below it, measured to the sides of the panel's box. In stone, a cut-out (a sink's, a hob's) must have at least 50 mm (2 in) of stone round it, measured to the nearest edge.
These are starting points: ask your processor for theirs, and change the GLASS table in rules.js to match (see
Design rules).
Designs in the library
File › Run Parametric… has a Glass folder (see Run Parametric):
| Design | What it is |
|---|---|
| Mirror | A rectangular, rounded, clipped, arched, oval or round mirror, with a bevel line and screw holes |
| Shower screen | A fixed screen with its top corner finished, wall-clamp holes or notches and a bracing bar hole |
| Splashback with sockets | A splashback with single and double socket cut-outs set out along it |
| Glass door with hinge notches | A frameless door: two or three hinge notches, handle holes, a lock notch |
Order list
File › Reports… › Glass order list lists each pane as a glass processor orders it: width × height, thickness (the drawing's T), glass, shape (rectangle, notched, or shaped: send the drawing as a template), edgework, holes by diameter, notches and cut-outs by size, toughening or lamination, quantity, area and edge length; holes and cut-outs nearer the edge than twice the thickness are flagged. Save it as a web page to print, or as CSV (the panes' table alone, with CSV: the order list only) for a processor's order import. See Reports.
Machine profiles
Make It (File › Export › Make It, Ctrl+Shift+M, or the Make It button at the top of the window) writes the cutting table's DXF (Glass cutting table (DXF shapes)) and the Glass order list as CSV in one click, beside the drawing, after checking the design: see Make It.
File › Export › Export… lists this trade's formats first. File › Send Using Machine Profile sends the drawing to a machine in one click, with the format, options, layer names and pens it needs; those that come with the app for this trade: Glass cutting table (DXF shapes), Waterjet (DXF, cut and etch). See Export by Industry and Machine Profiles.
