Description
The PartDesign Thickness tool transforms a solid body into a hollow object with at least one open face, giving to each of its remaining faces a uniform thickness. It adds a Thickness object to the document with its corresponding representation in the Tree view.
Base solid (A) → Solid with selected face to be opened (B) → Resulting hollow object (C)
Usage
Add a thickness
- Make sure the correct body is active. If required double-click it in the Tree view.
- Select one or more face(s) of the active Body.
- There are several ways to invoke the tool:
- Press the Thickness button.
- Select the Part Design → Apply a dress-up feature → Thickness option from the menu.
- The Thickness parameters task panel opens. See Options for more information.
- Press the OK button to finish.
- Remember:
- Since there must be at least one face for the feature, the last remaining face in the list cannot be removed.
Edit a thickness
- Do one of the following:
- The Thickness parameters task panel opens. See Options for more information.
- Press the OK button to finish.
Options
- Add face: Add faces to the selection by pressing the Add face button and selecting more faces.
- Remove face: Choose a way to remove faces from the selection:
- Select one or more faces in the list and press the Del key or right-click the list and select Remove from the context menu.
- Press the Remove face button. All previously selected faces are highlighted in purple. Select each face to be removed.
- Thickness: Set the wall thickness either by editing the value or by clicking the up/down arrows.
- Mode:
- Skin: Select this option if you want to get an item like a vase, hollow with only a single opening.
- Pipe: Not implemented. See this forum topic.
- Recto Verso: Not implemented. See this forum topic.
- Join Type:
- Arc: When non-tangential faces are offset, new faces that do not intersect are joined by a fillet with a radius equal to the defined thickness.
- Intersection: When non-tangential faces are offset, new faces that do not intersect are extended to meet at their virtual intersection.
- Intersection: This checkbox seems to be obsolete.
- Make thickness inwards: When checked, faces are offset inward.
Example
- Create a Pad from the sketch
- Create a second sketch on the XY plane
- Create a second Pad from the second sketch
As in the following pictures:

Properties
See also: Property editor.
A PartDesign Thickness object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:
Data
Base
- DataBase (
LinkSub
): Sub-link to the parent feature's list of selected edges and faces. - DataSupport Transform (
Bool
): "Include the base additive/subtractive shape when used in pattern features. If disabled, only the dressed part of the shape is used for patterning". Default:false
. - Data (hidden)Add Sub Shape (
PartShape
) - Data (hidden)Base Feature (
Link
): Link to the parent feature. - Data (hidden)_ Body (
LinkHidden
): Link to the parent body.
Part Design
- DataRefine (
Bool
): "Refine shape (clean up redundant edges) after adding/subtracting". The default value is determined by the Automatically refine model after sketch-based operation preference. See PartDesign Preferences.
Thickness
- DataValue (
Length
): "Thickness value". Default:1 mm
. - DataMode (
Enumeration
): "Mode".Skin
(default),Pipe
orRecto verso
. OnlySkin
is implemented. - DataJoin (
Enumeration
): "Join type".Arc
(default) orIntersection
. - DataReversed (
Bool
): "Apply the thickness towards the solids interior". Default:false
. - DataIntersection (
Bool
): "Enable intersection-handling". Default:false
.
Notes
- At least one face to be opened must be selected.
- If thickness goes inwards, the value must be smaller than the smallest height of the Body.
- The command may fail with complex shapes. In this context the surface of e.g. a cone has already to be regarded as complex.
- Additive Pipe or Additive Loft may work better to create complex shapes
- Known errors:
- BRep_API: command not done
- BRep_Tool: no parameter on edge
- Silently Fails
