소개

이 자습서에서는 기술도면 작업대 페이지의 배경 템플릿으로 사용할 수 있는 SVG 파일을 만드는 방법을 보여줍니다.

이 자습서에서는 여러분이 잉크스케이프와 SVG, 그리고 프리캐드와 기술도면 작업대에 대해 어느 정도 알고 있다고 가정합니다.

우리는 가로 방향으로 US Letter 크기 용지에 맞는 간단한 템플릿을 만들어 보겠습니다.

이 자습서의 결과 사본은 아래에서 찾아 볼 수 있습니다.

$INSTALL_DIR/Mod/TechDraw/Templates/HowToExample.svg

여기서 $INSTALL_DIR은 프리캐드가 설치된 디렉토리입니다. 예: 

/usr/share/freecad/Mod/TechDraw/Templates/HowToExample.svg

기본 문서 만들기

1. 잉크스케이프에서 새 문서를 엽니다.

2. 문서 속성에서

3. Use the XML Editor to add a "freecad" namespace clause to the <svg> item.

Note that your editable texts will not work if you use "https://...", even though the wiki is reached via https these days.

Since SVG is a human readable format you can also enter the line above into the file with a text editor.

Inkscape: XML Editor adding the "freecad" namespace clause to the <svg> item

Create template drawing

4. Draw outlines, zone numbers, center lines, and other geometry.

5. Draw the boxes and lines for the title block.

6. Add and position your static text.

7. Add and position the text that will be editable.

8. You now have your finished artwork, that should look something like this:

Inkscape: tentative template layout

Create editable fields

9. Use the XML Editor to add a freecad:editable tag to each editable <text> item.

Inkscape: XML Editor adding the "freecad:editable" property to the desired <text> item

Adjust size of the SVG

10. Use the XML editor to adjust the viewBox attribute to match your page size in millimeters.

Inkscape: XML Editor adjusting the viewbox to match the page size in millimeters

11. Your template will now appear much bigger than desired.

Inkscape: tentative template layout exceeding the page size

12. We need to shrink it.

13. Use "Align and Distribute" or the X: and Y: spinboxes to position the artwork within the limits of the page if required.

14. Your template should now look right, just like it did in the finished artwork picture above.

Remove transformans on the SVG

15. Ensure that all your editable texts are "ungrouped" with Shift+Ctrl+g.

16. Select everything on your page, Edit → Select All, and then Edit → Copy (Ctrl+c).

17. Then delete the current layer, Layer → Delete Current Layer.

Note: if you deleted the layer already (in your layer panel is no layer listed) this step is not required. In that case you should select all (Ctrl+a), cut the selection (Ctrl+x) and paste it with the command in the next step.

18. Then paste, Edit → Paste in Place.

Note: This command prevents that the text positions are stored in transform tags. It's important that you do not use the normal paste command!

19. Your template should now look right and shouldn't have any unwanted transforms.

20. Save your template. When you use Inkscape, save it preferably as Plain SVG because FreeCAD can only handle the features of the SVG 1.1 specification. Plain SVG will remove any Inkscape-specific XML tags.

21. Try it in FreeCAD and TechDraw Workbench with Insert Page using Template.

Notes

Don't use Layers in Inkscape until you've mastered template creation without them. Layers and Groups can automatically insert unwanted transforms into your SVG file.

As a final step before using your new template, make sure to remove any transform clauses from the Svg code. Transform clauses will cause problems.

See a Stackoverflow discussion on removing transform clauses in SVG files.

If you do not see the green boxes for your editable texts, there might be something wrong with your document scale. Open your file in Inkscape again and confirm the values of the viewBox and the sizes are matching.

If texts appear offset in FreeCAD, you may need to remove the xml:space="preserve" attributes in the SVG file. See: https://www.forum.freecadweb.org/viewtopic.php?t=50897.
