How to create presents with a ribbon in SOLIDWORKS
- Create a Sketch of the desired shape and extrude out to form a basic box.
- Sketch a cross to create a split line to detail the ribbon later on. This could also be done with a 3-D sketch or individual sketches on each face which are then extruded.
- Once the 4 sides have been detailed sketch out the ribbon shape for the top. As this will be designed to look as if it’s being pulled in by the bow it will taper in towards the centre. (Note: You can use a mirror or circular pattern here to speed things up)
Once sketched, extrude out to 1mm.
- Sketching on either the right or front plane, Draw out the exterior shape of the knot for the centre of the bow. Use surface extrude and extrude equally in both directions.
- Repeat the same process for the bow and the bow trail to give the basic shape for one side. We can add detail and mirror the bow later on. Note: These sketches were created using splines.
- You can see below how the surface extrude was created for the angled bow trial. The spline was sketched on a new plane which was created by referencing perpendicular faces of the box. Doing this forms a new plane angled at 45degrees between each selected face.
- Once each section of the bow has been completed, we can look at adding detail to each surface. To start we will re-shape the trail of the bow. In this example a new sketch was drawn on the top plane of the shape we wanted to trim the bow to. This sketch was then surface extruded to intersect the bow. This can then be used to cut the bow using the trim tool in surfacing. Below you can see the before and after.
- Now that we have the correct shape for each surface, we can use freeform tool to create a natural looking ripple effect. To manipulate the surface we need to add either curve lines, curve points or both. These are used as points or lines to transform the surface.
- Once you are happy with the finished surface, repeat the same process for the other two surfaces we have created.
- All of the surfaces are now complete. These surfaces need to be converted into a solid. For the bow, use the thicken feature to give it a thickness of 1mm to match the flat ribbon we drew out on the top of the box. For the knot, use 2 surface fills for both open ends to highlighting the setting to knit surfaces and create a solid.
Once the surfaces have been converted to a solid, we can mirror the result and combine bodies to form the finished bow.
- Now the shape is complete, use fillets to tidy up the edges of the box
- The present is complete! For the final touch we can add some colour.
Bonus: You can create multiple configurations and display states to produce different sizes and colours from a single part. Enjoy your presents!
