Uploader:     hakke gmx de (Andreas Winkler)
Type:         misc/sci
Version:      1.0
Requires:     AmigaOS 3.1+, 68030+FPU, MUI 3.8+
Architecture: m68k-amigaos
Distribution: Aminet
Kurz:         Betrachter für Sprint-Layout- und Gerber-Platinen

LayView shows printed circuit boards drawn with Sprint-Layout 6 (.lay6)
and boards given as Gerber + Excellon drill files (or a ZIP of them), the
files PCB makers work with. It is a viewer: it does not change the files.

Features
--------
- 2D view: all layers (copper, silkscreen, inner layers, outline), the
  ground plane with clearances and thermals, through-hole pads in their
  own color, color schemes (Sprint-Layout, Eagle, KiCad, dark, paper),
  top or bottom side, part numbers and values on or off, whole
  silkscreen on or off.
- Photo view: a side as the made board looks (solder mask, gold or tin
  finish, silkscreen).
- X-ray: all layers see-through, in 2D and 3D.
- 3D view: the board as made, from any side, with drill holes and edges.
  Wireframe while you drag, the full picture when you let go. Choice of
  mask color, finish and board thickness.
- PiStorm3D: on a PiStorm with a Raspberry Pi 4 the 3D view can be drawn
  by the Pi's graphics chip (minigl.library), a few ms per picture
  without antialiasing.
- Pan, wheel zoom, Fit, Zoom 100% (real size, for your monitor's size),
  turning in 45 degree steps or freely, a grid with rulers in mm or inch.
- Info window: board summary and a parts list; pick a part to find it on
  the board, or click a part on the board.
- Antialiasing (2x2, 3x3) on screens with more than 256 colors.
- Runs on RTG (CyberGraphX, Picasso96) and native screens, down to 4
  colors.
- Exports: IFF ILBM, PNG and JPEG pictures of the view; Gerber RS-274X +
  Excellon drill files (choose which, one ZIP if wanted); a 1:1 PDF, one
  page per layer (mirrored for toner transfer if wanted); parts list and
  placement files (CSV, as JLCPCB expects them).
- Gerber import (RS-274X/X2 + Excellon, from KiCad and other CAD
  programs); LayView works out which file is which layer.
- Settings are saved; a full AmigaGuide manual (HELP key).

Requirements
------------
- 68030 or better with FPU (68881/68882, or a 68040/68060).
- AmigaOS 3.1 or newer, MUI 3.8 or newer.
- About 2 MB of free memory for a typical board, more for big boards
  and the 3D view (with PiStorm3D about 6 MB more).
- Recommended: a graphics card and a screen with more than 256 colors.
- Optional: PiStorm + Raspberry Pi 4 with PiStorm3D's minigl.library.

Installation
------------
Copy the LayView drawer wherever you like. Double-click LayView, or
Shift-click board files and double-click LayView, or start it from the
Shell: LayView board.lay6. See LayView.guide.

Freeware
--------
You may copy and pass on LayView freely, also on CD-ROMs and other
collections, as long as the archive stays complete and unchanged.

This program is freeware. If you enjoy using it and would like to buy me
a cup of coffee, small tips are very welcome via PayPal, to the same email
address above - but they are never expected, and nothing in the program
is held back for anyone who does not.
