- Open the file Jacket_vent for this exercise. (Download the practice files before starting this tutorial.)
- To do so, navigate to the CLO Tutorial folder, which was previously added in the Introduction to CLO tutorial, within the Library. Go to C_Details, then b_Constructing a Vent. Double click on the file, Jacket_vent, or drag and drop it into either the 3D or 2D Window.
Using the Fold Arrangement Tool to Fold a Vent
Tracing a Fold Line
- The Fold Arrangement tool can only be applied to Seamlines and Internal Lines. Thus, Chalk Lines and Baselines must be Traced as Internal Lines in order to fold them.
- The fold lines are marked by purple Baselines on the Patterns. Select the Trace tool from the 2D Toolbar and click on both Baselines to Trace them as a single Internal Line.
- With the Baselines selected, hit the Enter key to generate the Internal Line.
- Since the Patterns have been Symmetrized, the Baseline only needs to be Traced on one of the Patterns. Symmetrically Pasted Patterns mirror one another, so if one of the pair has an Internal Line added to it, the other will reflect this change.
Folding a Vent
- Hover the mouse over the 3D Garment Display icon (the first icon of the Vertical View Toggle Menu) and a horizontal row of icons will appear. Select Show Internal Lines to display the Internal Lines on the garment.
- Select the Fold Arrangement tool from the 3D Toolbar.
- Click on the newly created fold line and the Fold Arrangement Gizmo tool will appear. If parts of the Fold Arrangement Gizmo tool are difficult to access, rotate around the Avatar until the tool is fully visible. Use the arrows to fold one side of the vent. Repeat for the other side.
Assigning a Fold Angle
- To fold the vent more precisely, assign a FOLD ANGLE to the fold lines. - Select the fold lines on the 2D Patterns with the Edit Pattern tool from the 2D Toolbar. Navigate to the Property Editor. Under Fold, set the Fold Angle to 0 degrees.
- Click on the Simulate icon in the 3D Toolbar to drape. When the Patterns are folded correctly, turn off Simulate.
Sewing a Vent
Establishing Sewing Lines
- Sew parts of the vent to refine its shape.
- Sew the top segments of the vent together. Then, sew the bottom of the vent on the wearer’s left to the wearer’s back left pattern of the jacket. Be mindful of Directional Notches. As the jacket back Patterns have been Symmetrically Pasted, the Sewing Lines established on the left side are reflected onto the right.
Changing Sewing Line Type
- There are two types of Sewing Lines: Flat and Turned.
- If overlapping Patterns are sewn with Flat Sewing Lines, there is a higher chance of collision and Simulation instability when they are folded together. To prevent this, change Flat Sewing Lines to Turned Sewing Lines within the Property Editor.
- To do this, select the Edit Sewing tool from the 2D Toolbar. Click on a Sewing Line and navigate to the Property Editor. Click the drop down arrow next to Sewing Line Type. Select Turned Sewing.
- The vent will now lay flat.
- Click on the Simulate icon in the 3D Toolbar briefly to reflect the newly added Sewing Lines.
- To hide the Internal Lines, navigate to and hover over the 3D Garment Display icon again. Select Show Internal Lines and the Internal Lines will no longer be visible on the 3D Garment.
