Description
Descriere
Part Extrude extinde o formă la o distanță specificată, într-o direcție specificată. Tipul formei de ieșire va varia în funcție de tipul formei de intrare și de opțiunile selectate.
În cele mai comune scenarii, lista de mai jos prezintă forma tip de ieșire așteptat de tip de formă de la o intrare/input dată.
- Extruderea unui vertex (punct), va produce o margine liniară
- Extruderea unei margine deschisă (de exemplu, linie, arc), va produce o fațetă deschisă (de exemplu, planul)
- Extrudează o margine închisă (de exemplu, cerc) va produce în cele din urmă o față închisă (de exemplu, cilindru nedeterminat) sau parametrul „solid“ este „adevărat“, va produce un solid (de exemplu, un cilindru solid închis).
- Extrude un filament deschis (de exemplu, un proiect de fire), va produce o cochilie deschisă (mai multe fațete îmbinate)
- Extrudează un filament închis (de exemplu, Draft Wire), va produce în cele din urmă o coajă (mai multe fețe atașat) sau, în cazul în care „solid“ este parametrul „true“, produce un solid
- Extrudare fețetei (de exemplu, un plan), va produce un solid (de exemplu, Cuboid)
- Extrude un Draft Shape String, va produce un compus solid (șirul este alcătuit din litere, care sunt fiecare un solid)
- Extruderea unei cochilie de fațete, va produce un Compsolid
Examples of extrusion
Usage
Cum se folosește
- Select the shape(s) in the 3D view or in the Model tree
- Click on the
Extrude icon in the toolbar, or go to the Part → Extrude menu - Set the direction and length and optionally other parameters (see the following Parameters section for more details).
- Click OK.
The Model tree will list as many Extrude objects as there were selected shapes. Each input shape is placed underneath its Extrude object.
Task dialog

- OK: creates the extrusion, and closes the dialog.
- Close: closes dialog, without doing anything.
- Apply: creates the extrusion, but does not close the dialog. You can then select another shape in the list on the bottom, and create more extrusions. Clicking Apply may times creates many extrusions.
- 'Direction' radio buttons: set the way extrusion direction is computed.
- Reversed checkbox: reverses the extrusion direction.
- 'Select' button: click it, and then pick an edge in 3D view. That edge will appear in text field next to the button, in format "ObjectName:EdgeN". You can also type the link manually. Values X,Y,Z will be filled according to the edge direction.
- X, Y, Z buttons: click X button to set extrusion direction to +X axis. Click it again to set -X axis.
- X,Y,Z input fields: set or display the direction vector of extrusion. If both lengths are zero, the length of this vector sets the length of extrusion, and values are always in mm, regardless of unit preferences.
- Length fields: set length of extrusion. These input fields have unit support.
- Symmetric: spreads out the extrusion into both directions, so that the profile remains in the middle.
- Taper Outward Angle: positive angle means profile is expanded at other end of extrusion.
- Taper angle against: idem for the against direction.
- Create Solid checkbox: if checked, extruding a closed wire or edge will yield a solid. It is checked by default, if a closed wire was preselected before invoking Part Extrude.
- Shape list: here you select, what shapes to extrude. If multiple objects are selected, multiple Extrude objects are created.
Notes
Contra intuitive/Gotchas
Dialogul Extrude Parts nu are încă o previzualizare. "Aplicați" creează un obiect de extrudare de fiecare dată când faceți clic pe el, ceea ce poate fi util ca previzualizare. Cu toate acestea, acestea vor rămâne și un altul va fi creat când faceți clic pe OK.Undo can be useful to clean them up before clicking OK.
Comparison with PartDesign Pad
PartDesign Pad este, de asemenea, o funcți(e)onalitate de extrudare, dar există diferențe importante.
- Part Extrude always creates a standalone shape. PartDesign Pad fuses the extrusion result to the rest of the Body.
- Part Extrude can be placed anywhere in the model tree. PartDesign Pad can only be placed inside a PartDesign Body.
- Part Extrude can extrude any object that has a Part geometry (OpenCASCADE shape), except for solids and CompSolids.
- Part Extrude can extrude individual faces of other objects. PartDesign Pad will only accept either Sketch or faces of PartDesign objects as a profile.
Properties
See also: Property View.
A Part Extude object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:
Data
Extrude
- DateBase (
Link): The shape to extrude. - DateDir (
Vector): The extrusion direction. If DateDir Mode isCustomyou can edit this property, otherwise it is read-only. - DateDir Mode (
Enumeration): Sets how DateDir is controlled.Custommeans DateDir is editable.Edgemeans DateDir is obtained from an edge (line) linked by DateDir Link.Normalmeans DateDir is perpendicular to the plane of the input shape. - DateDir Link (
LinkSub): Parametric link to an edge (line) that sets the extrusion direction. - DateLength Fwd (
Distance): Length of extrusion along direction. If both DateLength Fwd and DateLength Rev are zero, the length of the DateDir vector is used. - DateLength Rev (
Distance): Length of additional extrusion, against direction. - DateSolid (
Bool): If true, extruding a closed edge or a closed wire will yield a solid. If False, a shell will result. - DateReversed (
Bool): Reverses the extrusion direction. - DateSymmetric (
Bool): If true, extrusion is centered at the input shape, and the total length is DateLength Fwd. DateLength Rev is ignored. - DateTaper Angle (
Angle): Applies an angle to the extrusion, so that sides of the extrusion are drafted by the specified angle. Positive angle means the cross-section expands. Inner structures receive the opposite taper angle. This is done to facilitate the design of molds and molded parts. - DateTaper Angle Rev (
Angle): Sets the taper for the reversed part of the extrusion (the part from DateLength Rev). - Date (Hidden)Face Maker Class (
String): Superseded by DateFace Make Mode (read-only). - DateFace Make Mode (
Enumeration): If DateSolid is true, the facemaker class to use when converting wires to faces, otherwise ignored. The options areSimple,Cheese,ExtrusionandBullseye(default).
