Manually Selecting the Parts in the Loop and Selecting Interacting Surfaces
In the New Stackup dialog box, under Assembly, if Select appears in the box, you must manually define the part loop and interfacing features. The part associated with the start feature of the Stackup is automatically included in the loop. The part appears transparent in the graphics window.
1. Select the next part in the loop - the part that mates with the first part. The selected part becomes transparent.
2. Select all parts in the loop ending with the part associated with the end feature in the Stackup definition. After the part loop definition has been completed, the number of selected components or parts appears, and all parts are hidden except the first two parts in the Stackup definition. The first part is displayed with normal visibility and the second part is transparent.

• If you select an incorrect part, you must select all the parts in the loop again.
• Select the alignment pins or fasteners that are used to position the parts to one another. The assembly shift through these parts is calculated if the loop definition includes the parts.

3. Select faces, edges, vertices, datum planes, axes, or points to define the assembly constraints between the features. Select features from the first part that is referenced in the prompt. The second part is displayed transparent for reference and may not be selected. The total and remaining numbers of mating faces and points appear.
After you select the feature from the first part, the first part becomes transparent and the second part becomes fully visible. You are prompted to select a feature of the second that mates with the first. After this second feature is selected, the first part is hidden and the third part is shown with transparency to help you select the next feature on the second part. This process of showing the part from which you need to define an assembly constraint feature and showing the adjacent part with transparency continues until you select all necessary assembly constraint references.

If you want to change any of the mating features, you can click  and start the process again.If one of the mating features is a slab or slot, click  to select two parallel surfaces with opposing outward normal to define the slab or slot feature. |
4. After all mating features have been selected, the display will change to show all components in the loop as transparent and all mating features will be highlighted to provide a visual confirmation of the Stackup loop.
5. Click OK to complete the Stackup definition.
