PartDesign Legacy/zh-tw

零件坊為複雜實物提供建模工具，基於特徵編輯法以創造單一連續實體. 且與 速寫坊 緊密相連.

何謂單一連續實體？ This is an item like a casting or something machined from a single block of metal. If the item involves nails, screws, glue or welding, it is not a single contiguous solid. 實際例子如，零件坊不會用於木椅建模，但是可用於其零件建模（椅腳、肋條、椅座等等）. 零件組合則用 組合坊，物件坊 或 草圖坊.



Basic Workflow
The sketch is the building block for creating and editing solid parts. The workflow can be summarized by this: a sketch containing 2D geometry is created first, then a solid creation tool is used on the sketch. At the moment the available tools are: More tools are planned in future releases.
 * [[Image:PartDesign_Pad.png|32px]] Pad which extrudes a sketch
 * [[Image:PartDesign_Pocket.png|32px]] Pocket which creates a pocket on an existing solid
 * [[Image:PartDesign_Revolution.png|32px]] Revolution which creates a solid by revolving a sketch along an axis
 * [[Image:PartDesign_Groove.png|32px]] Groove which creates a groove in an existing solid

A very important concept in the PartDesign Workbench is the sketch support. Sketches can be created on standard planes (XY, XZ, YZ and planes parallel to them) or on a planar face of an existing solid. For this last case, the existing solid becomes the support of the sketch. Several tools will only work with sketches that have a support, for example, Pocket - without a support there would be nothing to remove material from!

After solid geometry has been created it can be modified with chamfers and fillets or transformed, e.g. mirrored or patterned.

The PartDesign Workbench is meant to create a single, connected solid. Multiple solids will be possible with the Assembly workbench.

As we create a model in the Part Design Workbench, each feature takes the shape of the last one and adds or removes something, creating linear dependencies from feature to feature as the model is created. Hence a "Cut" feature is not only the cut hole itself, but the whole part with the cut. As a new feature is added to the model, FreeCAD turns off visibility of the old features. The user usually should only have the newest item (feature) in the model tree visible, because otherwise the other phases of the model overlay each other, and holes are filled in by the earlier model features that didn't yet have those holes.

To toggle visibility of an object on or off, select it in the hierarchy tree and press the Spacebar. Usually everything but the last item in the hierarchy tree should be greyed out and therefore not visible in the 3D view.

The Tools
The Part Design tools are all located in the Part Design menu that appears when you load the Part Design module.

They include the Sketcher Workbench tools, since the Part Design module is so dependent on them.

Data


Every feature has a placement that can be controlled through the Data Properties table. It controls the placement of the part with respect to the coordinate system. NOTE: The placement properties do not affect the physical dimensions of the feature, but merely its position in space! If you select the title Placement, a button with appears to the right. Clicking this button, opens the Tasks_Placement options window.

An angle is set here, and the axis that the angle acts upon is set with the axis property. The feature is rotated by the specified angle, about the specified axis. A usage example might be if you created a revolution feature as required, but then needed to rotate the whole feature by some amount, in order to allow it to line-up with another pre-existing feature.

The exact value of rotation comes from the angle property (above). This property takes three arguments, which are passed as numbers in the x, y, and z boxes in the tool. Setting a value for more than one of the axes will cause the part to be rotated in each axis, by the angle value multiplied by the value for the axis. For example, with an angle of 15° set, specifying a value of 1.0 for x, and 2.0 for y will cause the finished part to be rotated 15° in the x-axis AND 30° in the y-axis.

This takes three arguments, which are passed as numbers to the x, y, and z boxes in the tool. Setting a value for more than one of the boxes will cause the part to be translated by the number of units along the corresponding axis.



PS: The displayed properties can vary, depending on the tool used.

There are two types of feature properties accessible through tabs at the bottom of the property editor:
 * : properties related to the "visual" display of an object.
 * : properties related to the "physical" parameters of an object.

View



 * : Indicates if a box showing the overall extent of the object is to be displayed. Value False, or True (Default, False).
 * : Indicates if the feature control points are to be displayed. Value False, or True (Default, False).
 * : Sets the accuracy of the polygonal representation of the model in the 3d view (tessellation). Lower values = better quality. The value is in percent of object's size (deviation in mm = (w+h+d)/3*valueInPercent/100, where w,h,d are the bounding box dimensions).
 * :Display mode of the feature, Flat lines, Shaded, Wireframe, Points [[IMAGE:Vue_DisplayModePartDesign_fr_00.png|96px]]. (Default, Flat lines).
 * : Lighting One side, Two side [[IMAGE:Vue_Lighting_fr_00.png|96px]]. (Default, Two side).
 * : Gives the color of the line (edges) (Default, 25, 25, 25).
 * : Gives the thickness of the line (edges) (Default, 2).
 * : Gives the color of the points (ends of the feature) (Default, 25, 25, 25).
 * : Gives the size of the points (Default, 2).
 * : Allows selection of the feature. Value False, ou True (Default, True).
 * : Give the color shape (default, 204, 204, 204).
 * : Sets the degree of transparency in the feature of 0 to 100 (Default, 0).
 * : Determines the visibility of the feature (like the bar ). Value False, or True (Default, True).

Data


Summary of the data below. Every feature has a placement that can be controlled through the Data Properties table. It controls the placement of the part with respect to the coordinate system. NOTE: The placement properties do not affect the physical dimensions of the feature, but merely its position in space! If you select the title Placement, a button with appears to the right. Clicking this button, opens the Tasks_Placement options window.

Specifies the angle to be used with the axis property (below). An angle is set here, and the axis that the angle acts upon is set with the axis property. The feature is rotated by the specified angle, about the specified axis. A usage example might be if you created a revolution feature as required, but then needed to rotate the whole feature by some amount, in order to allow it to line-up with another pre-existing feature.

This property specifies the axis/axes about which the feature is to be rotated. The exact value of rotation comes from the angle property (above). This property takes three arguments, which are passed as numbers in the x, y, and z boxes in the tool. Setting a value for more than one of the axes will cause the part to be rotated in each axis, by the angle value multiplied by the value for the axis. For example, with an angle of 15° set, specifying a value of 1.0 for x, and 2.0 for y will cause the finished part to be rotated 15° in the x-axis AND 30° in the y-axis.

This property specifies the base point to which all dimensions refer. This takes three arguments, which are passed as numbers to the x, y, and z boxes in the tool. Setting a value for more than one of the boxes will cause the part to be translated by the number of units along the corresponding axis.

The Label is the name given to the object (feature), this name can be changed as desired.

PS: The displayed properties can vary, depending on the tool used.
