Atelierul TechDraw (Desen Tehnic)
FreeCAD este în primul rând un instrument de modelare 3D. Există totuși momente când trebuie să realizăm desene 2D pentru documentație, contracte, permise etc. Banca de lucru tehnică de desen tehnic (TechDraw) este utilizată pentru a realiza desene tehnice de bază bazate pe modelul 3D. Fiecare desen este o pagină, iar o pagină conține multe vizionări ale obiectelor desenate. Lista obiectelor care pot fi desenate include Piese :: Caracteristici, PartDesign :: Corpuri, Aplicații :: Grupuri de piese și Grupuri de obiecte tip document.
Dimensiunile și zonele hașurate pot fi adăugate la vizualizări.
Rețineți că dacă obiectivul dvs. principal este producerea de desene complexe 2D, vă recomandăm să luați în considerare un instrument dedicat, cum ar fi LibreCad, QCad, TurboCad etc.
Pages
These are tools for creating Pages.
- File:TechDraw New Default.png New Default: Adds a new Page using the default Template.
- File:TechDraw New Pick.png New Pick: Adds a new Page using a selected Template.
Views
These are tools for creating Views.
- File:Techdraw-view.png New View: Adds a 2D View of a one or more Drawable Objects.
- File:Techdraw-projgroup.png New Projection Group: Invokes a dialog for creating Views of one or more Drawable Objects from multiple directions.
- File:Techdraw-viewsection.png New Section: Adds a cross-section View of one or more Drawable Objects.
- File:Techdraw-viewdetail.png New Detail: Adds a detail View of a portion of an existing View.
- File:Techdraw-annotation.png New Annotation: Adds a text block to a Page.
- File:Techdraw-draft-view.png New Draft: Adds a View of a Draft module object.
- File:Techdraw-arch-view.png New Arch: Adds a View of a Arch module Section Plane object.
- File:Techdraw-spreadsheet.svg Spreadsheet: Inserts a view of a selected spreadsheet into a drawing.
Clips
These are tools to create and manage clipped views.
- File:Techdraw-clip.svg Clip: Inserts a clip group into a Page.
- File:Techdraw-clipplus.svg ClipPlus: Adds a View to a clip group.
- File:Techdraw-clipminus.svg ClipMinus: Removes a View from a clip group.
Dimensions
These are tools for working with Dimensions. Linear dimensions can be based on two points, one line or two lines.
- File:Dimension Length.png New Length: Adds a Length Dimension.
- File:Dimension Horizontal.png New Horizontal: Adds a horizontal distance dimension.
- File:Dimension Vertical.png New Vertical: Adds a vertical distance dimension.
- File:Dimension Radius.png New Radius: Adds a Radius dimension to a circle or circular arc.
- File:Dimension Diameter.png New Diameter: Adds a Diameter dimension to a circle or a circular arc.
- File:Dimension Angle.png New Angle: Adds an Angle dimension between two straight edges.
- File:Dimension Link.png New Links: Links 1 or more Dimensions to 3D geometry.
Import/Export
These are tools for exporting Pages to other applications.
- File:Techdraw-saveSVG.png Save SVG: Saves a Page as an SVG file.
- File:TechDraw SaveDXF.png Save DXF: Saves a Page as a DXF file.
Decoration
These are tools for changing the appearance of Pages and Views.
- File:Techdraw-hatch.png Hatch Area: Applies a hatch pattern from a file to a Face.
- File:Techdraw-geomhatch.png Geometric Hatch: Hatches a Face using an Autodesk PAT specification.
- File:Techdraw-symbol.png New Symbol: Inserts an SVG symbol into a Page.
- File:Techdraw-image.png New Image: Inserts a png/jpg image into a Page.
- File:Techdraw-toggleframe.png Toggle Frames: Turns View frames and labels on or off in a Page.
Additional features
- Hatching: TechDraw supports a number of hatching techniques.
- Line Groups: default weights can be assigned to various line types.
Preference settings
The TechDraw module has a preferences screen to adjust default values.
Scripting
The TechDraw module features a Python API so you can use its functions in scripts and macros.
Limitations
- TechDraw drawings and Python API are not interchangeable with the Drawing module. It is possible to convert Drawing Pages to TechDraw Pages using Python (moveViews.py). It is possible to have both TechDraw and Drawing Pages in the same FreeCAD document.
- There are minor differences in specifying Editable Texts in Templates compared to the Drawing module. See forum discussion here.
- TechDraw is available starting with FreeCAD 0.17.
- Do not Cut/Copy/Paste TechDraw objects. This does not generally work out well.
Workarounds
- None required at the moment.
