Today we will be looking at a great new enhancement that has been rolled out with the new release of SOLIDWORKS 2018; the ability to mirror 3D Sketch entities. While mirroring 2D sketch entities has been possible for well over a decade, it can be invaluable in the way a designer goes about creating a model. 3D sketch entities, on the other hand, have remained impossible to mirror – until now. New in SOLIDWORKS 2018, 3D sketch entities can be mirrored, drastically improving the way parts are created using 3D sketches.
To show this feature, a set of handlebars will be designed for this chopper. Utilizing the mirror entities tool in a 3D sketch will assist in accomplishing this task with far fewer steps than before.
Layers have been available for many years in SOLIDWORKS, allowing users to assign drawings entities to them and control many visual aspects including visibility as well as line color, thickness, and style. New in SOLIDWORKS 2018, hatches can be added to layers, providing even greater flexibility when working with cross sections or adding hatches manually. In this article, we’ll cover how to create layers, assign hatches to them, and control hatch color. For added flair, we’ll be working with the deadly, motorized fidget spinner shown below.
Hatches are only available in drawings, and can be manually applied to closed contours/regions or automatically generated by cross section views. A quick cross section of the model shown in Figure 1 results in the drawing view shown below.
Figure 2 – Cross Section of Fidget Spinner Assembly
Before assigning the hatches to layers, the layers must first be created. Click Layer Properties to access the Layers dialog (as this command is not available in the menus or CommandManager by default, use the Search Commands option or enable the Layer toolbar in order to access it). If using a default template, a single FORMAT layer will be shown. Click New to add a new layer, optionally changing the name or adding a description. The remaining column icons can be used to toggle the layer visibility, printing, color, line style, and line thickness, respectively. In this example, 5 additional layers have been created with adjusted colors.
At this point, the hatches can be assigned to the created layers, and will inherit their visibility, print, and color properties (line style/thickness settings do not apply to hatches). Click a hatched region to reveal the Area Hatch/Fill PropertyManager, then (if necessary) click the Apply To dropdown to specify which portion of the view will be assigned to the new layer. Selections include the whole component, the selected region, the entire view, or a single body. Finally, click the Layer dropdown to select a new layer for the hatch. A checkbox under the Options group box can be selected to apply the changes immediately, or cleared to defer the changes until the Apply button is clicked.

If desired, the Material Crosshatch checkbox can be cleared to override the default material hatch pattern and make adjustments as needed. Simply click OK to save all changes. At this point, any further changes to layer properties will be reflected by the hatches assigned to them. If all hatches are added to a single layer, their visibility, print status, or color can be adjusted simultaneously in just a couple clicks.

Tabs and slots are commonly used to align interlocking sheet metal components, and the new Tab and Slot feature in SOLIDWORKS 2018 allows for corresponding tabs and slots to be created in one operation. This is definitely easier than using a complicated design library feature or separate extrude, cut, and pattern features.
The required selections for the Tab and Slot feature are the edge to add tabs to and the face for the slots. The tabs can be offset from either end of the edge. The spacing can either be set with an equally spaced quantity or spacing length. The length of the tabs needs to be specified and the height of the tabs can be defined with different end conditions. Fillets or chamfers can be added if needed. And the clearance between the tabs and slots can be specified.
Some other notes about the Tab and Slot feature:
Two linked features are created in the FeatureManager Design Tree (one for the tab and one for the slot).
It can be inserted at any position along the slot body.
Groups can be used to manage multiple edges.
It works with planar and cylindrical geometry.
The bodies do not need to be in contact.
It works on regular, non-sheet-metal solid bodies as well.
SOLIDWORKS does not synchronize property values between models and drawings on its own. For example, if a drawing note or field uses the $PRPSHEET method to link to a model property, the value present at the time the drawing is saved is cached inside the drawing. This is viewable in eDrawings. If the linked model property is changed while the drawing is closed, the new value will not be viewable in eDrawings. The eDrawings viewer can only access the properties of the immediate document it is viewing. To get these model properties to stick in the drawings we either need to make sure we always have the model and drawing open and editable at the same time, or employ an outside method of synchronization.
Properties in PDM
SOLIDWORKS PDM uses variable attributes to map data card variable values to the Custom Properties of our SOLIDWORKS files. This is a bidirectional link that will write to the file if the card value changes. You will observe in PDM that edits to card variables with these attribute mappings established require the file be checked out and will increment the version of the file on check in, since those edits are in fact changing the file. These attribute mappings are where we can establish a link between the model properties and the drawing properties. Examine our example variable and its attributes.
You will note that a CustomProperty attribute for all SOLIDWORKS extensions is accompanied by a $PRPSHEET attribute for drawings. Under very specific conditions these settings will copy the model variable value to the drawing variable, writing it into the drawing’s Custom Property. This link is global to the variable for your entire vault. If you require that some drawings do not carry the values of their models this link will not work, and you may need to look at other methods of synchronization, or use another variable.
The specific conditions enabling this synchronization are:
The drawing must contain a note linking to the model properties
The data card for the model and the drawing must both contain the variable to be linked
The drawing must be saved in the proper context
These are some possible contexts for saving or check in your drawing:
Save the drawing from SOLIDWORKS in a vault folder with the PDM add-in enabled
Save the drawing from SOLIDWORKS in a vault folder with the PDM add-in disabled
Save the drawing from SOLIDWORKS outside the vault
Check in the drawing from Explorer
Context #1 is the only one that synchronizes these variable values. When using the one model to many drawings option where each drawing represents one model configuration scenario #1 will still always synchronize. This is due to the drawing data card only populating the @ tab with one model configuration’s properties.
If one model produces many configurations where a single drawing file uses multiple sheets to show a single configuration per sheet the trick to maintaining proper links is to set each sheet’s properties to look at a specific view. See the screen capture below.
The variable mappings inside SOLIDWORKS PDM will not assist in this type of configuration-per-sheet link. You will notice the drawing data card has a tab for each sheet, but the referenced model’s configuration properties will not appear there.
Scenarios #2 and #3 will not perform the synchronization. No amount of rebuilding or saving will match the drawing’s custom property with the model’s custom property. The drawing may appear correct, since the notes are pulling from the model’s properties directly. But the eDrawings preview may be incorrect if the drawing has not been opened and saved with the new model property value.
Forcing the Issue Outside PDM
CUSTOMTOOLS Professional is a SOLIDWORKS add-in that provides the synchronization in either direction, from model to drawing, and from drawing to model. This works independently from your PDM environment, so users will need to follow standard vault editing procedures to ensure write access is available, and enabled.
Synchronizing these properties through the data cards in PDM can have some advantages, especially when it comes to searching for those values. Since the drawing sheet tabs typically contain no data specific to them apart from manual entry a special add-in must be employed to carry out this operation. The HAWKWARE team created just such a tool, called Sync Card Variables.
The bounding box is an indispensable piece of reference geometry in SOLIDWORKS, representing the smallest area or volume in which a design can fit. While available in weldment and sheet metal models for many years, creating a bounding box for a standard part has required convoluted workarounds – until now. New in SOLIDWORKS 2018, bounding boxes can be created for standard parts with just a few clicks, enabling you to quickly find the maximum dimensions of your design and use the automatically-generated file properties as needed. To emphasize the utility of the bounding box, an organic shape will be used.
Figure 1 – Standard SOLIDWORKS Part with Organic Geometry
Finding the maximum extents of the design shown above would be an exceptionally difficult task without the use of a bounding box. To create one, simply navigate to Insert -> Reference Geometry -> Bounding Box in the dropdown menus. In the PropertyManager, you’ll find two methods for creating a bounding box. While both methods result in the creation of a 3D sketch and file properties, Best Fit will generate the absolute smallest box in which the design can fit, regardless of orientation, while the Custom Plane option allows for the selection of a planar element to define one of the directions of the box. Additional options allow for a preview of the bounding box, and inclusion of hidden bodies and/or surfaces.
Once created, the bounding box exists as a feature in the Design Tree, and can be edited, suppressed, or hidden like any traditional feature. As changes are made to the model, the bounding box will update parametrically while preserving the original settings, but beware when using the Custom Plane option, as model changes may result in a missing reference.
Creating a bounding box for a part also generates a number of file properties automatically, which can be linked to drawings, or otherwise used just like manually-added properties. Click File Properties in the standard toolbar, then the Configuration Specific tab to view these new properties, which include the length, width, height, and even volume of the bounding box.
It should be noted that for multibody parts, creating a bounding box using this method will include all bodies (unless hidden). As such, it’s not currently possible to create separate bounding boxes for each body individually using the new Bounding Box command. However, there are multiple workarounds available to accomplish this, including saving the bodies to discrete part files, leveraging configurations/display states to show a single body at a time, or following the established workaround for creating bounding boxes prior to 2018. Please see our video on this workaround for more information.
As seen here, SOLIDWORKS 2018 allows for the creation of a bounding box and file properties for standard parts in just a few clicks, and this capability is just one of many exciting new enhancements this year.

Have you ever wanted to create a pattern of an object in an assembly, but also have every instance slightly rotated from the last? In models such as a spiral staircase, it can be time consuming to create all the features separately to achieve one simple task. For example, first a circle would have to be sketched. Then, a Helix and Spiral would be needed to create the curved shape. After that, a Curve Driven Pattern could be used as the final step. Now with SOLIDWORKS 2018, an enhancement to the Linear Pattern feature in assemblies has been created that allows this to be done in one step!
In 2018, when creating a Linear Pattern, you have the option to add a rotation to each instance simply by checking the Rotate instances box. Select your number of instances, rotational reference as well as the increment angle and you can create various patterning possibilities with different outputs. You also have the option to align rotated instances to the seed instance by checking the Align to seed box. This not only will save time in the creation of your design, but also make it easier to modify in the future by not having to adjust multiple features.
Figure 1: Rotated stairs with 20 degree increments
Here are a few examples where I used this new feature in some of my designs. I hope you found this informative. Comment below with ideas for designs you could use this new and cool enhancement on.
Today, we’re going to be diving into a SOLIDWORKS 2018 new enhancement on a widely used SOLIDWORKS feature – Pack and Go! We’ll see how we now have an option to ‘Include suppressed components’ in our Pack and Go in 2018!
First off, what is Pack and Go?
Pack and Go, if you’ve never used it, is a lifesaving feature! It allows you to gather all the referenced files for your drawings or assemblies, and either add them to a specified folder or add them to a zip file!
This is useful for a variety of different situations – some of which are, but not limited to:
Creating copies of whole assemblies, including referenced parts, while being able to append a prefix or suffix to the new files
Sending drawings and assemblies to a vendor or customer, ensuring we grab all the files necessary for vendor or customer to open them!

Today, we’re going to be diving into a new SOLIDWORKS 2018 sketch enhancement when working with arcs and splines – reverse endpoint tangency! We’ll see the various situations where this new tool can help complete both simple and complex sketches.
Before 2018, when sketching a tangent arc or making two splines tangent to each other – this would happen:
The arc or spline would flip the opposite tangency you were aiming for. Do you remember how you fixed it? Often, I found myself having to delete the arc and spline and recreating them.
Hello (again if this isn’t the first blog you’re reading from me), and welcome to my article on some key enhancements with flattening routes in SOLIDWORKS 2018. In case you aren’t familiar with it, routing is a module that lets you create 3D models of pipe, tube, and electrical routes and is available in SOLIDWORKS Premium. Flattening is the way to represent electrical routes in a 2D fashion for drawings. It’s not this kind of flattening.
I have the routing add-in turned on and I’m working on an electrical harness with a few branches and connectors.
I’ve already used the Flatten Route command and have 2 different styles of flattened routes in the Feature Manager Tree. These are saved as configurations that you can switch to once they are created.
I’m going to start with an annotation flattened view that shows all of the connectors and wires but isn’t to scale. The first enhancement I want to show off is the ability to right-click on a connector or segment and view the connected segment or connector respectively.
This can help you easily identify what goes to where and to make sure things are connected the way you want.
The second enhancement that I’m going to cover is that you can now move around the entire route in its flattened state. To show this, I’ll switch over to the manufacture view in which the harness is to scale and there is a form board outline.
From Figure 8, you can see that the harness isn’t fitting into the outline of the form board. Prior to SOLIDWORKS 2018, to change this you would need to right-click and select Edit Flattened Route to change the X and Y positions. Now, when you right-click you can select the command Move Connected Route Segments.
Once you are in this mode, an XY indicator shows up in the graphics area allowing you to drag the harness to where you want. Alternatively, key in values in the Property Manager.
If you choose to drag it, a ruler shows up that helps you move things a set distance. This is a nice shortcut to help you get things positioned perfectly.
The Advanced Hole command made its debut in SOLIDWORKS 2017, allowing users to create complex multi-step holes in a single feature. Despite already being an impressive time saver in the design process, the command has seen significant improvements this year. New in SOLIDWORKS 2018, callouts can now be added to Advanced Holes with minimal effort. In this article, we’ll investigate how to add these annotations to an existing model. It should be noted that Advanced Holes created in SOLIDWORKS 2017will not be capable of generating callouts, and must be recreated in SOLIDWORKS 2018.
