The Thicken/Offset command adds or removes thickness from parts and creates offset surfaces from partor other . When you select Output, you determine if the feature is a solid, a surface, or a new solid body. If you select Surface, the result is an offset surface. If you select Solid, the result is a thicken feature. If you select New solid, the result is a new body in a multi-body part. Each feature type is shown in the browser with a unique icon.
The following images show various thicken or offset solutions.
Thicken adds or removes material from the model and therefore changes its mass properties. When you add thickness to a surface, the model is converted from a surface to a part.
Thickenedand offset cannot be created in one feature. Thickness features and offset features have individual icons in the browser.
No. You cannot use Edit Feature to change an Offset Surface feature to a Thicken feature or vice versa. The feature type is determined by your selection of the output type. Offsets are surface features while thicken is a part feature. Each feature type creates an individual icon in the browser.
You can, however, thicken an offset surface. This operation places a thicken icon below the offset surface icon in the browser.
Surfaces must be adjoining to be offset at the same time. The offset result is a copy of the selected geometry (such as face, fillet, adjacent face, and so on).
Vertical surfaces can only be created from the internal boundaries of aface.
When importing complex surfaces, you can experiment with the file format. IGES and SAT files are commonly used formats when converting models you receive from a vendor, for example.
In a precise solution, each point of the original surface has a corresponding point on the offset surface. The distance between the two points is equal to the specified distance. An approximate solution enables Autodesk Inventor to deviate from the specified distance to find an acceptable solution.
You can control where the deviation is allowed to occur, as well as the accuracy of the approximation. Keep in mind that the more accurate the approximation, the longer it takes to compute. Approximate solutions are provided only when a precise solution does not exist and when an approximate solution can be found. If approximate solutions are not acceptable, you can turn this option off.
Each time approximation is used, the tolerance of the deviation is reported.
On the ribbon, click to:
Use the Automatic Face Chain option to select tangent continuous part faces. Use the Create Vertical Surfaces option to add sides between the original surface and the offset surface.
Thicken and Offset features are indicated by separate icons in the browser.
A thicken operation adds or removes volume from parts or adds thickness toto create parts or new solid bodies.
You can offset one or more faces from a part face or a. Offset surfaces do not add or remove mass.
If desired, you can create copies of surfaces with a zero distance offset, but not surfaces with vertical sides. This can be useful when you want to make a copy of an entire surface body or a set of individual faces from any solid model or surface.
Adds or removes thickness to faces of a part or acreates an offset surface from a part or , or creates a new solid.
Sets requirements for a Thicken or Offset feature.
Specifies faces to thicken or faces from which to create an offset surface.
|Solids||Selects the participating body if there is more than solid body present.|
Filters geometry so that selections are restricted to individual faces or a quilt. You can select multiple connected faces or a quilt, but not mixed faces and quilts.
Specifies thickness of the Thicken feature or specifies distance for the Offset feature.
When the output is a surface, the offset distance can be zero (to create a copy of a surface or individual faces from a solid model or surface).
Specifies if the feature is a solid or a surface. The default selection is a solid.
Specifies whether the Thicken feature joins, cuts, or intersects the solid part.
Join Adds the volume created by the Thicken feature to the solid part.
Cut Removes the volume created by the Thicken feature from the solid part.
Intersect Creates a new feature from the shared volume of the Thicken feature and the solid part. Material not included in the shared volume is deleted.
| ||New solid Creates a new solid body. This is the default selection if the thicken operation is the first solid feature in a part file. Select to create a new body in a part file with existing solid bodies. Each body is an independent collection of features separate from other bodies. A body can share features with other bodies.|
Extends the Thickness or Offset feature either direction or equally in both directions.
Automatic blending is a re-blending technology that automatically moves adjacent tangential faces and also creates new blends if required. It is active by default in the part modeling environment.
The illustrations below show a model with a Thicken operation performed with and without automatic blending.
No Automatic Blending
Automatic Blending Enabled
The Automatic Blending check box is only active when solid faces are selected for a Thickness operation. It is also active when the Thickness feature is extended in the positive or negative direction, but not when the feature is extended equally in both directions.
When automatic blending is enabled, the following Thicken functions are automatically deactivated:
Provides method for selecting chained part faces or creation of surfaces with sides. Also enables and sets characteristics of approximate offset solutions.
Automatic Face Chain
Use to select multiple tangent continuous faces to thicken. All selected faces thicken with the same Boolean operation and direction. Default setting is Off.
Create Vertical Surfaces
For offset features, creates vertical or "side" faces connecting the offset faces to the original quilt. Vertical surfaces are created only at internal surface edges, not at boundary edges of surfaces. Default setting is Off.
Vertical surfaces cannot join an offset surface to the solid part.
When no precise solution exists, allows a deviation from the specified thickness while computing the offset feature. A precise solution creates an offset surface where each point on the original surface has a corresponding point on the offset surface. The distance between these two points is the specified distance.
Select whether to allow an approximate solution, and then click the arrow to select the deviation type from the list.
Mean deviation is divided to fall both above and below the specified distance.
Never too thin preserves minimum distance. The deviation must fall above the specified distance.
Never too thick preserves maximum distance. The deviation must fall below the specified distance.
Computes using a reasonable tolerance and minimal compute time.
Computes using the specified tolerance. Considerable computation time may be required. Click the option and then specify a tolerance.
