Using Geodesic Offsets on Complex Curves in SOLIDWORKS

My architect friend was recently commissioned to design a community center. His client’s mandate was that the building had to be pointing to a monument on the other side of the world. My friend did not see this as a problem and proceeded to design the structure. When he presented his project, the client was appalled because it seemed like the building was pointed in a totally different direction. My friend tried to explain that he used a geodesic path to point the building in right direction. He said that if he used the Euclidian method, the building would be pointing infinitely into space, or he would have to point the building into the Earth. It became a heated debate between my friend and the client and suffice it to say he ended up not getting the commission in the end. My friend may have been able to make his…

SOLIDWORKS 2018 3D Sketch Mirror

For a long time, I’ve liked 3D Sketching, but I’ve always missed one important function: Mirror. I love using Mirror in a 2D Sketch, and the function is as old as SOLIDWORKS in a 2D Sketch. But how about a 3D Sketch Mirror? My friends, the long wait is over! SOLIDWORKS 2018 finally has 3D Sketch Mirror. Wondering what it is like? Let’s take this example: Anyone who has taken the SOLIDWORKS Advanced Part Modeling course will immediately recognize this spring. During the lesson, we used a Fit Spline to eliminate the tangent edges, but when we apply the mirror, we get an edge at the mirror plane due to the fact that the faces are not continuous. Avoiding this edge is a lot of extra work! Let’s see how we can do this differently in SOLIDWORKS 2018. I delete the mirror feature knowing that if I can do the…

Using a solid model as reference geometry for creating a SOLIDWORKS Weldment Sketch

There are a lot of techniques for creating a SOLIDWORKS Weldment Sketch on the web and in the help file. Despite that fact we are often asked what is the easiest and most effective method of creating a Weldment Sketch. In this blog article, I will show you a quick method of using a solid model as reference geometry when creating your 3D Sketch. The following image depicts a 3D solid model created by a boss extrude with a draft angle. Having the basic knowledge of SOLIDWORKS part modeling helps to quickly create the required shapes. This solid body represents the shape of my required weldment. Convert Edges to a 3D Sketch Now that we have a solid body created, start a new 3D sketch and then run Convert Entities to select and convert all the edges of the solid model into the active 3D sketch. In this case, every single edge has…

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.

Marble Roller Coaster Create Start of Loop (Part 6 of many) [VIDEO]

Create Loop Start To read the previous article of this series, CLICK HERE. Many people believe that the shape of the loop should be circular, the problem with a circular loop is that it has an abrupt change in curvature and in the case of a loop causes a significant loss of speed at the top of the loop.  The shape that we should use for this loop is a clothoid. For more information on clothoids see here: http://www.math.hmc.edu/~gu/curves_and_surfaces/curves/clothoid.html This shape starts with 0 curvature and then spirals, which is the perfect shape for a loop because the marble will not hop, and it will not lose a significant amount of speed.  However this shape is very complex to model in SolidWorks, we can generate coordinates and create a curve.  But even getting the coordinates is a fairly complex task.  As a simple workaround I will demonstrate sketching by tracing…

SOLIDWORKS Weldment Bounding Boxes

This functionality has been long time requested by SOLIDWORKS users like you, as a quick way to determine the smallest box you can package your model in. Watch this video and tell the good news SOLIDWORKS brings to your colleagues from the estimating and shipping departments. They will love you for that! Update: After I finished creating this video I realized that this new functionality will be priceless for users involved with 3D Printing by minimizing the support material and the printing times. I am pretty sure you have spotted the same opportunity, but, just in case you are in doubt, I will try to prove this point next week with a second video on how to use the new bounding boxes enhancement for saving time and money while 3D…

Routing: How the “Flip Relation” Option Can Speed Up Routing Sketch Edits

Occasionally when modifying a routing sketch (or other 3D sketch) you may run into a scenario where a spline tangent needs to be flipped or reversed.  See the image below. Well, thankfully there is a way to quickly flip it.

3D Sketching Techniques – Insert points and Connect the Dots

This method assumes that you have a list of points that you wish to sketch to.  Start a 3D sketch as usual.  Using the “point” tool on the sketch toolbar, drop in the needed number of points.  Click on each point in turn in the model window and set the point location in the PropertyManager, once the point coordinates are set, add a fix relation to each point.  Once all the coordinates are set, you can now start the line or spline tool and click on each point to achieve the desired sketch path.
