The images below show two 3D printed components that can be used to give plastic bottles a second life.
The first part can be used to make a simple sprinkler, while the second part can be used to transform a larger bottle into a makeshift mudguard.
The SolidWorks “Mirror Part” feature can be used to create an equal and opposite version of an existing part. Parts that are linked by a Mirror feature can be updated quickly, as any changes to the parent model will be reflected instantly in the linked part.
Mirrored parts can either be managed as separate files or as separate configurations within the one file. The drawings below look at several ways that Mirrored parts can be referenced within an assembly.
There are many ways to layout and structure manufacturing drawings in SolidWorks. A typical product will comprise multiple levels of custom parts, assemblies, sub-assemblies, OEM components and multi-bodied parts.
The image below shows one way of structuring manufacturing drawings under a top level General Assembly drawing.
The flow diagram below shows a method for investigating User Needs by looking at the specific tasks that the product will have to perform. These headings would have their own category in the PDS, as shown in the lower image.
Aligning a fastener in a slot is a typical task in CAD modelling, and with SolidWorks there are number of different ways to do it. This post will look at some different methods that can be used for “mating” a fastener in a slot, trying to identify the method that is most stable and easy to edit. Click the images below to view them at full size.
The CAD model below shows four fasteners aligned in slots, using four different sets of mates:
The middle-right fastener is constrained with two Symmetry mates, one acting in the X-Axis and one acting in the Y-Axis:
The top-right fastener has a Concentric mate aligning the cylindrical surface of the fastener with the centre point of the slot feature sketch (below-left).
The middle-left fastener uses a horizontal Symmetry mate, like the fastener before, except this time it is used in combination with a vertical Width mate (below-right).
The final lower-left fastener uses a coincident mate to align the Temporary axes of the fastener and the slot feature (below-left). This is the best method I have found so far, but it relies on the slots having a temporary X-Axis, which relies on the slot being created in the right way.
The above-right image shows two slots – one that’s been created with a “Straight Slot” sketch feature and one that’s been created with a combination of line and arc sketch features. It can be seen that the “Straight Slot” feature has a Temporary Axis through its centre, whereas the slot created with line and arc features does not. I’d be interested to know if this is different in SolidWorks 2014.
