Creating a Surface from a Mesh Feature in SOLIDWORKS 2018

When a *.stl or *.obj file is imported into SOLIDWORKS, the 3D model opens in a tessellated or meshed form. All faces are broken into some triangular faces. Round faces will have more segments than flat faces. In SOLIDWORKS 2017 a *.stl file could be converted into solid body, however, it will still be tessellated. New in SOLIDWORKS 2018 is the Surface From Mesh tool, it lets you manipulate a mesh object that you imported from an *.stl, *.obj, *.off, *.ply, *.ply2 or *.3MF file to create surfaces and solids. The Surface From Mesh tool works best on mesh files with regular prismatic geometry such as planes, cylinders, cones, and spheres. The tool may not be appropriate for highly irregular meshes such as those created from a 3D scan of an organic shape. Because the feature only creates surfaces, the recommended workflow is to trim the surfaces to form a solid. Import Tessellated Model To…

Expanded use of the Perpendicular Mate in SOLIDWORKS 2018

SOLIDWORKS Perpendicular Mate

Like many enhancements that come along during any SOLIDWORKS release cycle, it seems like the ability to add a SOLIDWORKS perpendicular mate between a complex (Non-analytic) surface and a linear entity, may get overlooked rather easily. UNLESS this is the exact feature you have been waiting for! A number of years ago I bumped into a designer who was working on a biopsy device to extract bone biopsy samples, and their example (although graphic) came clearly to mind when I was investigating this new feature.   The customer would regularly have 3D scanned data of the most non-analytical type surfaces there are – us humans! They were hoping for an easy method to mate the central axis of their designed device, perpendicular to the surface of the bone scan – in preparation for animations and illustrations. It takes a great number of enhancements to make up each release of SOLIDWORKS,…

How to use SOLIDWORKS Surfaces as Reference Geometry for Mates

SOLIDWORKS Surface Reference Geometry

Dummy/reference surfaces can be utilized for various design situations in SOLIDWORKS. Due to the fact that the surfaces have no thickness and do not contribute to the weight or mass properties of the parts or assemblies. Surfaces are useful as reference geometry and can then be hidden from view.  In this blog as describe an example of using dummy surfaces as reference geometry for a mate in an assembly. SOLIDWORKS Surface Reference Mate Example Mating spherical joints in SOLIDWORKS can be a bit of a challenge depending on the required settings and final application. In the following image a handle and a base plate are shown which are connected with a ball joint. A specific movement is required for the assembly. The handle can only move as far as it hits the sealing/edge of the base. The ball on the end of the handle must  always be tangent to the bottom of its seat in…

SOLIDWORKS 2017 Streamlines Surface Trimming Workflow with Offset On Surface

SOLIDWORKS Offset on Surface Midway

Among the many new features in SOLIDWORKS 2017 are features that “Clean Up” or simplify the entire process of creating some types of models — the SOLIDWORKS Offset on Surface tool is one of these. Let’s see how this tool can be put to use. Take a look at the following example of this complex surface from which we would like to remove the center and leave a “Ribbon” around the outside of the shape. Use of the SOLIDWORKS Offset on Surface tool will permit us to easily generate a complex 3D sketch that exactly matches the surface. The resulting 3D sketch can then be used for a trim operation in order to finish up the feature.

SOLIDWORKS 2017 Wrapping sketches over complex surfaces

SOLIDWORKS Wrap Feature

Every year an exciting new version of SOLIDWORKS comes out with shiny new features that have been requested by users. SOLIDWORKS 2017 is definitely no exception with plenty of new tools to geek out about. In this blog we’ll be discussing the enhanced SOLIDWORKS Wrap feature in 2017. If you saw our first teaser video for SOLIDWORKS 2017 you might of guessed that it relates to the Wrap feature. The SOLIDWORKS Wrap feature has always been a great way to project sketches onto 3D geometry, up to SOLIDWORKS 2016 we have only been able to Wrap sketches over Cylindrical and Conical shapes, well with the added functionality in SOLIDWORKS 2017 you can now wrap over complex surfaces as shown in the figure below: SOLIDWORKS Wrap Feature The user interface for the Wrap feature has an added button to indicate that the text you are using can be wrapped around a complex surface. Simply select this option when using…

New methods of converting Surface into Solid with SOLIDWORKS

When working with surfaces in SOLIDWORKS you would typically be converting Surface into Solid using the Knit Surface or Thicken Surface feature. But with the latest versions of SOLIDWORKS you now have the ability to create a solid using the Boundary Surface or the Trim Surface features, provided the surface features can create a closed volume from the inputs. The ‘Create Solid’ option now included with these features was formerly called ‘Try to form solid’, and in previous releases, you often had to use the Knit Surface tool to combine the surface manually before you could convert the surface into a solid. Converting Surface into Solid using Trim Surface Let’s have a look at a simple example of creating a solid using the Trim Surface feature. Here we have a cell phone button design comprised of two surface bodies (shown in the surfaces folder in the tree). I want to generate a solid model from the two surfaces. I should be…

Creating Swept Rods & Tubes in SOLIDWORKS 2016

Swept Feature Example

The SOLIDWORKS Sweep Feature has been enhanced for the SOLIDWORKS 2016 release. There is a new Circular Profile option to create a solid rod or hollow tube along a sketch line, edge, or curve directly on a model without having to sketch. This enhancement is available for Swept Boss/Base, Swept Cut, and Swept Surface features. Enhanced SOLIDWORKS Sweep Feature In this example I’ll create a swept rod onto a pool slide surface without creating a circular profile sketch: To start I’ll select Insert > Boss/Base > Sweep. Pick the new Circular profile option from the PropertyManager. Specify a size for the profile in this example I’ll enter 50mm. Then pick a path for the sweep, in this example I’ll pick an edge of the slide surface, a preview of the sweep will be displayed: Pick OK and the swept feature will be added to the model as shown in the example below: Learn more about the Sweep Feature…

SOLIDWORKS 2016 Flatten Surface Tool Enhancements [VIDEO]

The SOLIDWORKS Premium 2016 Flatten Surface Tool provides more control and more variations of surfaces that can be flattened. You can flatten any face, surface, or set of faces with internal geometries such as holes or extruded cuts. You can select curves and sketches on the surface to flatten. You can also select curves, sketches, and edges on the surface to be relief cuts or split lines. When you select these entities in the graphics area or the FeatureManager design tree, they display in the Flatten PropertyManager. Check out the video below to see the SOLIDWORKS 2016 Flatten Surface Tool in action: To flatten a surface: In an open part, click Flatten (Surfaces toolbar) or Insert > Surface > Flatten. The Flatten PropertyManager displays. Select faces in the graphics area or from the FeatureManager design tree. Then select a vertex. A preview of the flatten surface appears. You can also choose to include relief cuts or not. In…
