Choose Your Weapon: Loft vs. Boundary Surfaces


Choose Your Weapon: Loft vs. Boundary Surfaces

In this on-demand webinar, TriMech Application Engineers, Laura Weismantel and Jason Pancoast, break down whether loft or surfacing commands are the best weapon for your application.

About This On-Demand Webinar

In this on-demand webinar, we break down the best times to use loft surfaces vs. boundary surfaces, so you can choose the best weapon for your application. Surface modeling is a needed skill because unlike working with simple solid models, surface models offer more flexibility and customization. Similar to sewing a custom t-shirt, SOLIDWORKS surface modeling allows you to hand-pick fabrics and tailor stitches (u-lines and v-lines) until you get the model you want. How much control you want to have over this surface is ultimately what will determine if you use the loft or boundary surface command.

While sweeps and lofts are on the left side of the boundary surface spectrum with u-biased, algorithmic, more accurate, and less smooth surfaces, the surface fill is on the opposite side with less orientation control, automatic and more smooth results. Boundary surfaces fall in the middle of the two, balancing analytical and automatic and weighing u and v equally.

After explaining the similarities and differences between the commands, we walk through how to build and modify these surfaces in SOLIDWORKS. Some factors to consider when determining to use loft surface commands versus boundary surface commands include:

  • Start and end requirements
  • Profile accuracy
  • Surface smoothness
  • Inputs
  • Interpolating vs extrapolating transitions
