Создание SVG-шаблонов

Создавать шаблоны для модуля чертежей (Drawing) легко и приятно. Смотрите также руководство по созданию шаблонов чертежей. Шаблон — это файл в формате SVG, который можно создать в любой программе способной экспортировать SVG, например Inkscape. Необходимо соблюдать только два правила:

  • 1 пиксель = 1 миллиметру.
  • Где-нибудь в SVG-код, там где будет размещаться содержимое чертежа, требуется вставить (например, в конец файла перед тегом </svg>) следующую строку:
 <!-- DrawingContent -->

In addition to these two rules, as of FreeCAD 0.14, Revision 2995, information about the Border and Title block can be added to the template for use by the orthographic projection tool. This information defines where FreeCAD can, and can not place the projections.

To define the Border, the following line must appear before the <metadata tag in the svg file.

<!-- Working space X1 Y1 X2 Y2 -->

Where X1, Y1, X2, Y2 are defined as:

  • X1 is the X axis distance from the left edge of the page to the left side of the Border.
  • Y1 is the Y axis distance from the top edge of the page the the top of the Border.
  • X2 is the X axis distance from the left edge of the page to the right side of the Border.
  • Y2 is the Y axis distance from the top edge of the page the the bottom of the Border.

To define the Title block the following line must be inserted before the <metadata tag and after the Working space tag.

<!-- Title block X1a Y1a X2a Y2a -->

Where X1a, Y1a, X2a, Y2a are defined as:

  • X1a is the X axis distance from the left edge of the page to the left side of the Title block
  • Y1a is the Y axis distance from the top edge of the page the the top of the Title block
  • X2a is the X Axis distance from the left edge of the page to the right side of the Title block
  • Y2a is the Y axis distance from the top edge of the page the the bottom of the Title block
  • X1a <= X1 or X2a >= X2
  • Y1a <= Y1 or Y2a >= Y2

XY Title v2.svg

The following is an example of the code that defines the Working space and Title block areas that are to be inserted before the <metadata tag. You needn't specify a title block, but if you do it must be defined on the next line immediately following the Working space:

<!-- Working space X1 Y1 X2 Y2 -->
<!-- Title block X1a Y1a X2a Y2a -->

In order to enable up to scale printing, the real word size has to be given in the width and height attributes of the SVG-Tag. The size of the document in user units, (px), has to be given in the viewBox attribute.

The following is to be formatted like the example below where:

  • xxx = pixel width
  • yyy = pixel height
width="xxxmm"
height="yyymm"
viewBox="0 0 xxx yyy"
  • Several custom attributes can be placed in templates. The list of currently supported attributes is available on the Svg Namespace page.

DXF templates

Since version 0.15, FreeCAD can reliably export a Drawing page to the DXF format. This system also uses templates. If a dxf file with the same name is found in the same folder as the SVG template used for a page, it will be used for export. If not, a default empty template is created on the fly.

Consequently, if you create your own SVG templates, and wish to be able to export the Drawing pages that you create with it to DXF, you just need to create a corresponding DXF template, and save it with the same name in the same folder.

DXF templates can be created with any application that produces DXF files, such as LibreCAD. You then need to edit them with a text editor, and add two additional lines, one at the beginning or end of the BLOCKS section, and another at the beginning or end of the ENTITIES section, which are where FreeCAD will add its own blocks and entities.

A very simple template looks like this:

999
FreeCAD DXF exporter v0.15
0
SECTION
2
HEADER
9
$ACADVER
1
AC1009
0
ENDSEC
0
SECTION
2
BLOCKS
$blocks
0
ENDSEC
0
SECTION
2
ENTITIES
$entities
0
ENDSEC
0
EOF

The above template doesn't contain any entity. If you create your DXF file with a CAD application, there will likely be much more content inside the HEADER, BLOCKS and ENTITIES sections.

The two lines that FreeCAD will be looking for are "$blocks" and "$entities". They must exist in the template, and they must be placed on their own line. You can choose to place them right after the BLOCKS or ENTITIES line, which is easier (just use the "search" function of your text editor to find them), or at the end, just before the "0 ENDSEC" lines (beware that there is one for each SECTION, make sure to use the ones relative to BLOCKS and ENTITIES). The latter method will place the FreeCAD objects after the objects defined in the template, which might be more logical.
