Solidworks How to Add Plan Tangential to Drawing
Utilizing SOLIDWORKS Reference Geometry for Complex Designs
For basic SOLIDWORKS models, users can often consummate designs past leveraging only the default planes and available model geometry. However, as the complexity of designs increases, it frequently becomes necessary to create and utilize reference geometry to produce models with appropriate blueprint intent. Reference geometry includes planes, axes, coordinate systems, reference points, the eye of mass, and mate preferences. In this article, nosotros'll cover the basics of creating planes, axes, and coordinate systems to assistance yous throughout your design process.
Fly Reel Design
In this example, a fly reel is being designed, and and so far everything has been polish sailing.
At this indicate, nosotros want to create a rectangular cut on ane of the larger cylindrical surfaces of the fly reel, but there is no apartment surface to create a sketch. While kickoff options in the Extruded Cut command could be used to attain this, creating a airplane tangent to the surface will be more robust, and will upshot in better design intent should the design be resized in the future.
Features Tab
All types of reference geometry are considered features and can be found in the Features tab. To brainstorm creating a plane, access the Features tab of the CommandManager, select Reference Geometry, and then click Aeroplane.
New Planes
New planes are well-nigh always defined by existing geometry, and at that place are several combinations of entities that tin be used. Upwards to iii references can be used to define the aeroplane, with simple planes often requiring only one. Some common combinations include a single face, 1 edge, and ane point/vertex, or three points/vertices. An example of a plane defined by 3 vertices is shown below:
FeatureManager Pattern Tree
In our case, a plane is needed that is both tangents to the larger cylindrical confront and parallel to the Right Aeroplane. This requires the choice of 2 references. It should exist noted that the order of reference pick is non of import. Select ane of the larger cylindrical faces, then select the right plane from the FeatureManager Blueprint Tree. You may need to utilize the flyout FeatureManager to brand aeroplane selections if they are not visible in the graphics area. The preview of the plane should await as seen below:
PropertyManager
Detect in the PropertyManager that several options still be to reorient the airplane, even though the plane is fully defined. In some cases, planes may fail due to these options being set incorrectly, so we recommend trying a few of them before changing your reference selections.
In this case, set 2d Reference orientation to parallel. This will change the orientation with respect to the Right Plane. If needed, the Flip Offset choice in the Commencement Reference box could be enabled to create the airplane on the opposite side of the cylinder.
Once complete, the newly created airplane should appear every bit seen below, and a new feature should be added to the Design Tree.
Newly Created Plane
At this point, we are ready to add together a sketch on the newly created plane. A simple rectangular sketch was created through the utilize of a corner rectangle, attached to the edges of the cylinder with a height of 0.1 inches. Still, ensuring that it is properly centered on the reel is not particularly piece of cake. This could be done with a combination of the midpoint and/or coincident relations, simply depending on geometry, these may not exist readily available.
Reference Axis
An alternative is to employ a reference centrality. Axes are ordinarily used for revolved features and circular patterns, particularly when no convenient sketch entity or model edge exists for those features. In this case, we will use an axis to assistance u.s. in centering the sketch.
Fortunately, axes are significantly easier to fully define than planes, and the associated PropertyManager is fairly self-explanatory and is shown below.
It's important to call up that in order to exist used as a reference in sketches or features, axes (or any reference geometry, for that matter) must exist prior to creating the sketch or characteristic that references them. In this instance, we've already completed most of the sketch, so to use an axis for centering, we would need to leave the sketch and use the rollback bar to create the centrality higher in the Design Tree.
Yet, in that location is ane more play a joke on that can be used, specifically when working with cylindrical or conical geometry. Every cylindrical or conical characteristic is automatically created with what is known every bit a temporary centrality, which follows a direct path through the heart of the feature. To leverage these automated axes, they must be made visible from the Hide/Show Items menu in the Heads-up View Toolbar:
Once the temporary axes were revealed, the center axis was used in conjunction with i of the midpoints of either vertical sketch segment to create a coincident relation, centering the rectangle with respect to the connecting shaft. Finally, an Extruded Cut was created to produce the feature seen below:
At this signal, let'southward suppose we demand to determine the coordinates of the centre of mass of the part. Luckily, SOLIDWORKS readily provides this information automatically in the Mass Properties dialog. Click on Mass Properties in the Evaluate tab of the CommandManager to run into these results. Additionally, reference geometry for the heart of mass location can exist created from inside this dialog, or from the Reference Geometry dropdown in the CommandManager.
While this information is helpful, it'southward possible that yous may run into a situation where the centre of mass is needed with respect to some other location (perhaps relative to mounting hardware) for downstream applications such as stress simulation. When this is the case, coordinate systems can be created and used to show this information. Coordinate systems can besides exist exceptionally useful for employ with the Measure out tool when exporting SOLIDWORKS parts to another format, or in facilitating assembly mates.
To prove the middle of mass relative to the mounting location of the fly reel, we've sketched a construction line on the large circular face up from the eye to the left quadrant in order to adhere the coordinate system. From here, create a coordinate system by accessing Reference Geometry on the Features tab of the CommandManager and select Coordinate Organisation. The first selection sets the origin, and as such should exist the construction line endpoint at the center of the reel. The remaining selections set up the orientation of the axes and can use linear or planar selections. It is not necessary to set every management to fully ascertain a coordinate organisation, and the reverse button may be used to flip the direction of an centrality.
The resulting model and coordinate organisation tin be seen below:
Finally, this coordinate system can be used to represent the middle of mass coordinates relative to this location. Access Mass Properties once again, and this time, use the Report coordinate values relative to the dropdown window to select the new coordinate organisation. The center of mass coordinates will update to the advisable values, as shown below (specifically in the Z direction). Your results may differ depending on the orientation of your coordinate system.
In this article, we covered the basics of using reference geometry in the context of designing a fly reel. Reference planes were added to facilitate an extruded cut on a not-planar confront, and a temporary axis was used to align the rectangular sketch properly. Finally, a new coordinate system was created to decide the coordinates of the center of mass from a relative location.
