Auto Detect Thin Solids
Click Refine Model and then click the arrow next to 
Control. Click 
Thin Solid > . The Auto Detect Thin Solids dialog box opens to automatically detect and create a thin solid AutoGEM control for your part or assembly model.
Control. Click Thin Solid > . The Auto Detect Thin Solids dialog box opens to automatically detect and create a thin solid AutoGEM control for your part or assembly model.The Auto Detect Thin Solids dialog box opens with the following options:
• Components—This collector is available only in assembly mode. Select assemblies or individual components in an assembly for which you want to create thin solids automatically.
• Thin Solid Detection Method—Detects thin solids based on the model features. You can also use the model geometry to detect thin solids. The following options are available in this section:
◦ Use Geometry Analysis—When you clear this check box thin solids are detected based only on feature creation. Feature creation methods that implicitly pair surfaces in your model include:
▪ Thin Solids
▪ Shells
▪ Ribs
▪ Ears
▪ Thin protrusions
▪ Sheet metal
▪ Plastic ribs
When you select Use Geometry Analysis check box, the model features as well as the model geometry are used to detect thin solids. This makes detection slower, but more pairs may be detected.
◦ Characteristic Thickness—When you select the Use Geometry Analysis check box, searches for all the thin solids with a thickness less than the value specified for Characteristic Thickness. By default, Characteristic Thickness is blank if the sim_auto_pairing_thickness configuration option is not set. Type a value greater than 0 for Characteristic Thickness. This value is retained for a session.
 | The geometry analysis method of thin solid detection only creates thin solids with a constant thickness. |
• Properties—Defines thin solid properties.
◦ Split Surfaces—Controls whether or not the automatically-detected thin solid controls are created with split surfaces. This check box is cleared by default. The state of the Split Surfaces check box on the Thin Solid Control dialog box also changes accordingly.
If you select Split Surfaces, all the automatically-detected thin solids are created with split surfaces. The Split Surfaces check box on the Thin Solid Control dialog box is selected.
If you clear Split Surfaces, the automatically-detected thin solids are created without split surfaces wherever possible. For the remaining thin solids, the surfaces are split.
The Split Surfaces check box is cleared when you create a thin solid pair using Auto Detect Thin Solids under the following conditions:
◦ Exactly one surface is on the top and bottom side of each of the auto-detected pairs.
◦ The top and bottom surfaces of the auto-detected pairs have the same contours and edges.
If either of the above conditions is violated, then the Split Surfaces check box is selected to create a thin solid pair.
