3 D Geometry Modifying 3 D Geometry Thin/Surface : – The Thin/Surface feature has two distinct applications: • Create thin solids (Thin). • Create simplified shelling (Surface). – Selections available from Details: • Faces to Remove: selected faces will be removed from their bodies. • Faces to Keep: selected faces will be kept, while unselected faces are removed. • Bodies Only: the operation will be performed on the selected bodies without removing any faces. – When converting solids into thin solids or surfaces you can specify a model's thickness in one of three offset directions: 1. Inward 2. Outward ANSYS Workbench - Design. Modeler • Training Manual 3. Mid-Plane December 17, 2004 Inventory #002176 5 -3

3 D Geometry Modifying 3 D Geometry… Notes on Thin/Surface: – The Thin/Surface feature

3 D Geometry Modifying 3 D Geometry… Notes on Thin/Surface: – The Thin/Surface feature supports thickness > 0 if the selected faces are part of surface bodies. – This allows for the “thickening” of an imported surface. • Mid Plane Option: – This does not mean midplane extraction. – Bodies will be hollowed, such that the inner and outer walls of the bodies are offset equal distances from the original faces. – Example : Resulting offset is in both directions.

3 D Geometry Modifying 3 D Geometry… Fixed Radius Blend: – The Fixed-Radius feature

3 D Geometry Modifying 3 D Geometry… Fixed Radius Blend: – The Fixed-Radius feature allows you to create blends on model edges. – You can select or preselect 3 D edges and/or faces for blending. • Face selection applies blend to all the edges from that face. – When preselecting, additional options are available from a RMB context menu (face edge loop selection, smooth 3 D edge chain) – You can edit the blend radius in the Detail View. Clicking Generate completes the feature creation and updates the model. • Variable Radius Blend (same as above plus): – Use the Detail View to change the start and end blend radius for each edge. Also, the Detail View can set the transition between blends to smooth or linear. Clicking Generate completes the feature creation and updates the model. • ANSYS Workbench - Design.

3 D Geometry Modifying 3 D Geometry… Chamfer: – The Chamfer feature allows you to create planar transitions (or chamfer face) across model edges. • You can select or preselect 3 D edges and/or faces for chamfering. • If a face is selected, all the edges from that face are chamfered. – When preselecting, additional options are available from a right mouse button context menu (face edge loop selection, smooth 3 D edge chain) • Every edge on a face has a direction. This direction defines a right and left side. – Chamfer is defined either by two distances from the edge for the planar transition (chamfer face), or by a distance (left or right) and an angle. – The type of chamfer is set up in the Detail View along with the distances and angle. • ANSYS Workbench - Design.

3 D Geometry Advanced Features Two Advanced Feature Properties described in this section apply

3 D Geometry Advanced Features Two Advanced Feature Properties described in this section apply selectively to the 3 D Features: 1. Target Bodies: Extrude, Revolve, Sweep, Skin/Loft, Slice, Import & Attach. 2. Merge Topology: Extrude, Revolve, Sweep, & Skin/Loft. • Target Bodies: allows users to specify which bodies are operated on during a Cut, Imprint, or Slice operation. – By switching the value of the Target Bodies property from “All Bodies” to “Selected Bodies”, the user can select bodies through another Apply/Cancel property called Bodies. Cut operation applied only to Selected Bodies ANSYS Workbench - Design. Modeler • Training Manual December 17, 2004 Inventory #002176 5 -20

3 D Geometry Advanced Features… Merge Topology Detail property for Extrude, Revolve, Sweep, &

3 D Geometry Advanced Features… Merge Topology Detail property for Extrude, Revolve, Sweep, & Skin – A Yes/No detail option that gives control over feature topology. >Yes: optimizes the topology of feature bodies. >No: leaves the topology of feature bodies unaltered. – The default setting for Merge Topology differs depending on the 3 D feature you are using: • Extrude: default is Yes • Revolve: default is Yes • Skin/Loft: default is No • Sweep: default is No Note: In version 7. 0 and earlier Merge Topology is a read-only property whose behavior is, inner profile faces are merged but outer profile faces are not. This means that features created in 7. 0 and older versions cannot be changed • ANSYS Workbench - Design. Modeler • Training Manual Example follows. . . December 17, 2004 Inventory #002176 5 -21

3 D Geometry Advanced Features… Training Manual Merge Topology = >Yes Merge Topology =

3 D Geometry Advanced Features… Training Manual Merge Topology = >Yes Merge Topology = >No • Setting the value to >Yes optimizes all topology of the feature body. It is however, recommended to leave this setting as >No (default) for the Skin/Loft and Sweep features. • Use caution when changing the value of the Merge Topology property. • Once other features depend on this, faces and edges may appear or disappear and cause failures and invalid selections for subsequent features.

3 D Geometry Advanced Tools… Normally, a 3 D solid feature operates like this: 1. Create the bodies of the 3 D feature (e. g. , an Extrude feature) 2. Merge the feature bodies with the existing model via Boolean operations: Add Material, Cut Material, Imprint Faces • The Freeze feature allows you to control the second step acting as a separator in the construction history as displayed in the Feature Tree. – Bodies created from features before a Freeze will become frozen – Frozen bodies are denoted by the ice cube icon next to the body’s branch of the Feature Tree – All frozen bodies are ignored by Add, Cut, or Imprint Material operation for any features following the Freeze – An example. . .

3 D Geometry Advanced Tools… Training Manual Unfreeze allows one to selectively “remove” the freeze from single or multiple bodies (freeze is a global operation) • Assembly notes: – By default if you import an assembly from a CAD package the assembly will remain as separate parts in DM without freezing – Any subsequent 3 D modeling operation however will result in a merge of any touching bodies in the assembly • This can be avoided with the Freeze and Unfreeze tools ANSYS Workbench - Design.
