CREO PARAMETRIC 6.0 – KATANA SWORD DESIGN_Part 4 – Scabbard Design

When a samurai doesn’t use his sword he let it in scabbard. The work design for this element goes as follows:

STEP 1.

Create new part in Assembly workbench as shown:

STEP 2.

In Model workbench, click on Sweep icon and then create the trajectory in a sketch on DTM3. Just project the upper top edge and extent the curve at tip and then create the sweep profile as shown:

STEP 3.

Fill in additional material on the inside groove with another Sweep feature. The trajectory curve is the middle arc created as concentric arc as shown:

STEP 4.

At the end of the tip side the scabbard must be closed. This is done also with a sweep feature as an offset of 2mm from the outer quillt as shown.

STEP 5.

Similarly with the closed end, create another sweep feature on the open side, also as a sweep of 2mm offset from the outer quillt. As shown:

STEP 6.

Create a sketch on the DTM3 made of a central curve as concentric arc with in the middle and add 6 datum points as shown.

STEP 7.

Create a new datum plane Normal to the previous sketched curve in the 1st datum point (Pct.1)

STEP 8.

Select the circular surfaces and create a 0mm offset for both.

STEP 9.

Keeping the previously created quilts selected, click the Trim icon and use the DTM4 as trimming element in the shorter direction as shown:

STEP 10.

Create another Sweep feature with the trajectory curve equally lenghthed (2.5mm on each side) from the 1st datum point (Pct. 1), then make an offset of 1.5mm from the initial surface as shown:

STEP 11.

Add a round of 0.5mm on side edges.

STEP 12.

In the model tree, select the last 2 features and in the pop-up menu click on Group icon to put these 2 feature together in a Local Group.

STEP 13.

Hold the previously created Local Group selected and click on Pattern icon to multiply the feature by the remaining 5 Datum points created at STEP 6.
