Creating Stitch in Alias – mainly for visualization Modeling a stitch in Alias helps designers to visualise their design in a much more compelling way.

Modeling a single stitch

A quick model can be generated using Surfaces -> Torus with the sweep set to 180 degrees and then applying non proportional scaling tool.

Fig 1

On the desired surface , create the path for the stitch by projecting a curve . Using Transform -> Duplicate Place tool , - Select the target object ( surface created previously ) ; click Accept Targets - Specify the number of duplicate stitch models & distance between them - Select the destination COS as created before ; click Accept duplicate Place

Define the path of the stitch

As seen in Fig 3 , the orientation of the stitch on the desired path is not what was desired. To adjust the orientation, rotate the target model by 90 degrees along Z axis as shown . The surface stitches change orientation as shown in Fig 4

With the construction history active, query Edit the objects on the path and select Elevate on the bottom right side of screen to adjust manually to the desired location visually . The stitch surface model also can be taken to a visualisation software application like Autodesk Showcase to generate a compelling visual imagery .
