When we start out with a model we usually have every intention of keeping the SOLIDWORKS Sketch clean, simple and easily understood. With continually compressed timelines, even the most basic sketches can turn into a mess…very, very quickly.
Consider the case of a simple sketch involving a rectangular profile used to cut a groove into a shaft, as shown in the figure below.
Reduce SOLIDWORKS Sketch Entities
One method that can assist us in steering clear of messy sketches, is to keep the number of sketch entities as small as possible — by using advanced functionality within our most basic features. While advanced methods can not address a lack of time in the day, it may at the very least shorten diagnosis if you run into any issues involving the sketched feature and bring some elegance to your feature tree.
Typically, the need for this type of shape can lead one to think about a revolved-cut feature, and indeed that would be one method to go about creating the cut.
If it aligns with our design intent, we can simplify the number of sketch entities required by choosing another feature entirely; a cut extrude feature with a very simple sketch.
Using advanced feature options
Through the use of the “From option” set to “Offset” along with the “Flip side to cut option” within the cut-extrude feature, we can accomplish all that is required to define an identical shape to the original groove using the simplified sketch geometry.
Building upon this very basic technique within one feature, take a look at how much of the advanced functionality you employing when generating your own components and designs. We are confident that you can find some sketch related efficiency in some of your most basic features.
