Title blocks

titleblock() in src/dd_titleblock.scad draws any block from three lists. The files in templates/ are ready-made blocks built on it.

All title block coordinates and sizes are in line widths, not model units. A block 290 units wide is 290 * DIM_LINE_WIDTH across: 7.25 at the default scale. A block therefore grows with SCALING_FACTOR, and its size is not tied to the sheet.

Templates

include <DraftSCAD/ddtemplates.scad> provides these. Each has its origin at its top-left corner and extends right and down. Each takes fill; when it is true, a white slab is drawn behind the block so a sheet grid does not show through.

titleblock0

titleblock0(part_details, doc_details, org_details, fill = "true")

A block 290 wide and 140 tall, in line widths.

Parameter	Contents, in order
part_details	Title, material, finish, weight, part number
doc_details	Drawing number, created by, reviewed by, date of issue
org_details	Logo text, organization name, organization address

include <DraftSCAD/ddtemplates.scad>
include <DraftSCAD/dimdraft.scad>

part_details = [ "My Sample Part", "Stainless Steel", "N/A", "2.5", "123" ];
doc_details = [ "33-2", "D. Smiley", "C. Brooks", "2013-3-31" ];
org_details = [ "My Logo", "Canny Machines", "Org Address, phone" ];

titleblock0(part_details, doc_details, org_details);

It is the block at the lower right of the Canny Machines example.

revblock0

revblock0(revisions, fill = true)

A revision table 121 wide, in line widths, with one row per revision. Its height is 15 * (2 + n) for n revisions.

revisions is a list of [revision, date, initials]:

include <DraftSCAD/ddtemplates.scad>
include <DraftSCAD/dimdraft.scad>

revisions = [
    [ "1a", "2013-4-1", "ds" ],
    [ "1b", "2013-4-2", "ds" ],
];

revblock0(revisions);

titleblock1

titleblock1(fill = true)

A block 330 wide and 100 tall, in line widths. Its contents are fixed sample text and cannot be set from outside; it is a worked example to copy from. It is the block in the Don Smiley example.

titleblock

titleblock(lines, descs, details, color = DEF_LINE_COLOR, text_color = DEF_TEXT_COLOR)

Draws a block from a list of lines and two lists of text. descs is meant for the small captions in each cell and details for the values; the two are drawn the same way.

Every entry in lines is [x, y, orientation, length, width]:

Field	Meaning
x, y	Start point
orientation	DIM_HORZ runs right from the start point; DIM_VERT runs down from it
length	Length of the line
width	A multiplier on the line width: 1 is normal, 2 is double

Every entry in descs and details is [x, y, orientation, text, size]:

Field	Meaning
x, y	Left end of the text baseline
orientation	DIM_HORZ, or DIM_VERT to rotate the text 90° anticlockwise
text	The string to draw
size	A multiplier on the text size: 1 is normal

include <DraftSCAD/dimdraft.scad>

// a single cell, 100 wide and 20 tall, with a caption and a value
lines = [
    [ 0, 0, DIM_HORZ, 100, 1 ],
    [ 0, -20, DIM_HORZ, 100, 1 ],
    [ 0, 0, DIM_VERT, 20, 1 ],
    [ 100, 0, DIM_VERT, 20, 1 ],
];
descs = [[ 3, -7, DIM_HORZ, "Material", 0.75 ]];
details = [[ 3, -17, DIM_HORZ, "Stainless Steel", 1 ]];

titleblock(lines, descs, details);

To make your own block, copy templates/titleblock0.scad and edit its column and row positions.

Planned change. Title blocks are to be generated from parameters, without hand-written templates: #3.
