This is the second version of my original sling bag design Linked here
Updates:
Dart pattern optimized
Center zipper lengthened
Flush handle added
Additional hypalon and webbing loops added for future expandable storage (water bottle holder?!)
Foam padded wings to contour the body when wearing on hip.
The first update was the pattern for the darted front pocket.
Due to the asymmetrical darts from top to bottom on the original bag, the darts are sitting inwards and there is tension pulling on them causing an uneven appearance on the entire front panel when at rest. (V1)
The fix was aligning the apex of the darts in a trapezoid, that allowed the fabric to conform in a more natural manner reducing the collapse of the dart at the apex. (V2)
The width of the main compartment was increased to keep the internal volume similar to the original.
From this angle you will also notice that the zipper for the main compartment is longer, allowing you to open the pocket up further.
The reasoning for the V1 bag featuring a shorter zipper path was due to the location of the Fidlock. If the Fidlock was placed any lower, the bag would be top heavy causing severe usability problems.
3d pattern making using Rhino
As my ongoing search for tools to improve my skills continues, I decided it was time to enter the 3rd dimension...
Using the measurements from V1 I created a rough model within rhino with the intent of flattening for pattern-making purposes VS modeling for visualization purposes.
Interactive model below:
I started in Rhino, building the surfaces and curves frame with an understanding of seam placement to separate out the surfaces.
Pattern is unwrapped using commands in rhino and exported to illustrator (1st image)
I cleaned all the open/intersecting lines and joined the darted panel (2nd image)
The last step is the standard seam allowance and pattern notes (3rd image)
