Utiliser les techniques de zoom de SOLIDWORKS pour visualiser les modèles cachés

Article by Brandee Videcak updated May 13, 2024


Have you experienced any of these scenarios in SOLIDWORKS?

  • Opened an assembly and the model has disappeared, but all of your parts are still in the SOLIDWORKS FeatureManager Design Tree.
  • You see little specks on your screen, as if something is there but it is not a dust speck.
  • You rotate your model and the part disappears, or the model display becomes erratic.

Then you may be a victim to a stray component within your assembly.

Using a combination of different SOLIDWORKS zoom techniques and tools is a good way to tell if you have a stray or outlying component.


The first step that I always do is use the Zoom to Fit tool, located on the Heads-Up Toolbar in the graphics area, under View > Modify > Zoom to Fit, or selecting the ‘F’ key on your keyboard.

This will modify the graphics area to show all the components in the assembly. While using this tool, if your model becomes really small, to a point where the main model has disappeared, then there is a more probable reason to believe there is a stray component in your assembly.

Outlying Parts Within an Assembly

A stray component can happen from time to time when moving a component, adding a new component, or moving an overall assembly in the graphics area.

To be able to determine which component is an outlier, there are a few different techniques and steps to determine this.

Select the Component in the Assembly FeatureManager Design Tree

The first technique is to select the individual components in the FeatureManager Design Tree. This technique is useful when there are not too many components and sub-assemblies within your model, and it is easy to pick through each element.

When selecting or hovering over a component in the FeatureManager Design Tree, there are a few things that you will see. You will see either the component being highlighted, a boundary box appearing around the component, or move symbols. The move symbols are only visible on components that are not fixed in the assembly.

SOLIDWORKS Zoom to Selection

Another technique for models that have a smaller amount of components would be to use the Zoom to Selection tool. This tool can be found by right-clicking on one of the components in the FeatureManager Design Tree, and selecting the Zoom to Selection option. This tool will automatically scale the graphics area, and zoom the view to the specific component.

This gives the ability to zoom slightly out after using Zoom to Selection and to be able to go back to the first technique to see which component is not visible.

After using the above method, and you have been able to determine which component is an outlier, then you are able to suppress or delete the component from the FeatureManager Design Tree. In some situations, determining the outlying component is not as simple, and you need to use additional tools.

These additional tools would be beneficial when you have a model that has many components and sub-assemblies, and it is not easily determined the outlying component.


After using the Zoom to Fit option to first determine the overall scale and size of the assembly, you can use the Zoom to Area tool to isolate the overall main assembly. The Zoom to Area tool is very similar to the Box Selection tool, but it will only scale the graphics area to the selected area, and not select the components. This tool can be found in the Heads-Up Toolbar or under View > Modify > Zoom to Area to enable the tool.

Using Box Selection

Once you have used the Zoom to Area tool, and isolated the main assembly, this is where the Box Selection Tool can come into play. By using the Box Selection tool, by left-clicking in the graphics area and selecting the overall assembly, all the components will be highlighted in the FeatureManager Design Tree. Ensure the Box Selection tool is enabled by going to Tools > Box Selection and making sure it is selected on.

You can then scroll through the FeatureManager Design Tree and see which components are not selected, strongly indicating the outlying component.

This is where you can go back to the above techniques and narrow down the scope if the unselected component is a sub-assembly or an individual component. If the unselected component is a sub-assembly, then you will need to go through the same steps for the sub-assembly.

These steps and techniques will allow you to get your model cleaned up and make it easier to continue working on your model.

If after these steps, you are still unable to determine if there is an outlying component, or having difficulties determining which component is causing the behavior, if any, please reach out to our Client Success Support Team who is more than happy to assist you further!
