Overview

The Property Editor is one of the most important tools of FreeCAD and a main element while working with FreeCAD. The Property Editor allows managing the properties of the objects in your document.

Generally the Property Editor is intended to deal with just one object at one time. The values shown in the Property Editor belong to the active object of your active document (be careful of which document is really active if you work on multiple documents). If you did not select any element (or there are no elements), the Property Editor will be blank.

Not all the properties can be modified in any moment. Depending on the specific status, some properties will be shown as read-only.

The properties of an object are grouped in View properties and Data properties, and shown under different tabs.

Different objects may have different properties. However, some properties are common among all objects, for instance the position and the rotation of an object are Data properties that can be manipulated.

Property definition

A property is a piece of information like a number or a text string that is attached to a FreeCAD document or an object in a document. Properties can be viewed and - if allowed - modified with the Property editor.

Properties play a very important part in FreeCAD, since it is from the beginning made to work with parametric objects, which are objects defined only by their properties.

Custom scripted objects in FreeCAD can have properties of the following types:

Boolean
Float
FloatList
FloatConstraint
Angle
Distance
Integer
IntegerConstraint
Percent
Enumeration
IntegerList
String
StringList
Link
LinkList
Matrix
Vector
VectorList
Placement
PlacementLink
Color
ColorList
Material
Path
File
FileIncluded
PartShape
FilletContour
Circle


Function

The Property Editor has two tabs: the View tab and the Data tab.

  • The View tab provides access to the properties related to the visual display of the object
  • The Data tab allows modification of the physical parameters of an object.

Example of Part object properties

Properties

There are two types of feature properties, accessible through tabs at the bottom of the Property editor:

VIEWView : properties related to the visual display of the object.
DATAData : properties related to the physical parameters of an object.

View

Base

  • VIEWBounding Box : To view the occupation, and, overall, of the object dimensions in space. Value False, or True (Default, False).
  • VIEWControl Point : Value False, or True (Default, False).
  • VIEWDeviation : Sets the accuracy of the polygonal representation of the model in 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 sizes of bounding box).
  • VIEWDisplay Mode :Display mode of the form, Flat lines, Shaded, Wireframe, Points Vue DisplayModePartDesign fr 00.png. (Default, Flat lines).
  • VIEWLighting : Lighting One side, Two side Vue Lighting fr 00.png. (Default, Two side).
  • VIEWLine Color : Gives the color of the line (edges) (Default, 25, 25, 25).
  • VIEWLine Width : Gives the thickness of the line (edges) (Default, 2).
  • VIEWPoint Color : Gives the color of the points (ends of the form) (Default, 25, 25, 25).
  • VIEWPoint Size : Gives the size of the points (Default, 2).
  • VIEWSelectable : Allows the selection of the form. Value False, ou True (Default, True).
  • VIEWShape Color : Give the color shape (default, 204, 204, 204).
  • VIEWTransparency : Sets the degree of transparency in the form of 0 to 100 (Default, 0).
  • VIEWVisibility : Determines the visibility of the form (like the bar SPACE). Value False, or True (Default, True).




Data

Base DATAAngle : The argument Angle, indicates the angle that will be used with the option Axis (below). Here, an angle is defined. The angle on the axis is set with the option Axis.
The object takes the specified angle around the specified axis.
An example, if you create an object with a required revolution should be rotate functionality of a certain amount, in order to enable it to take the same angle that another element existing.

DATAAxis : This option specifies the axis/axes to rotate the created object. The exact value of rotation comes from the angle (see above) option.
This option takes three arguments, these arguments, are transmitted in the form of numbers, x, y or z. Adding a value, more of an axis, will the rotation to each specified axis angle.
For example, with a Angle of 15 ° : specifying, 1.0 for x and 2.0 for y, will rotate 15 ° and 30 ° in the y-axis and the x-axis (final position),

DATABase : This option specifies the offset in either axes x, y, or z, and accept any number as the argument for each field.

DATALabel : The Label is the name given to the operation, this name can be changed at convenience.

DATAPlacement : [(0.00 0.00 1.00);0.00;(0.00 0.00 0.00)] Summary below 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 options do not affect the physical dimensions of the feature, but merely its position in space!
If you select the title Placement Options Placement, a button with three small points appears, clicking this button ..., you have access to the options window Tasks_Placement.

DATAAngle : The Angle argument specifies the angle to be used with the axis option (below). An angle is set here, and the axis that the angle acts upon is set with the axis option. 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.

DATAAxis : This option specifies the axis/axes about which the created feature is to be rotated. The exact value of rotation comes from the angle option (above). This option takes three arguments, which are passed as numbers to either the x, y, or z boxes in the tool. Adding a value to more than one of the axes will cause the part to be rotated by the angle in each 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.

DATAPosition : This option specifies the base point to which all dimensions refer. This option takes three arguments, which are passed as numbers to either the x, y, or z boxes in the tool. Adding a value to 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.
