How to increase SOLIDWORKS performance when working with downloaded Vendor models

Article by Vicky Guignard created/updated August 29, 2017

Working with downloaded Vendor models can be an issue, since these are often. STEP or .IGES files. You may not have full control over the level of detail included in the model. One of the main causes of slow SOLIDWORKS performance is due to the level of detail being displayed on screen. For vendor models, we usually only need the outer shell for representation and certain faces to mate to.

Per example, I have a downloaded a step file of an Automation Bottle Machine. I do not require the inside components as this will only be represented for spacial requirements in a plant layout. There are certain things you can do to simplify your imported file:

Simplify Imported File Technique #1: Delete internal components

When opening a step file from the open file window, under file type, I will select step file. The reason I am doing this is that after I will be presented with an options box. When selecting OPTION, you will be presented with this window. This is where you can specify how you are going to import your .step (or .iges file) as a multi body part, or an assembly file.

In this case, I want to remove ALL internal components from this step file. So, I will CLEAR the option to MERGE BODIES and CHECK the option to create separate parts for each body as shown in the image below:

When opening the STEP file, it will open as if it was an assembly, giving me assembly options!

First thing I will do is REMOVE THE INTERNAL COMPONENTS by using the Select Internal components filter from the advanced selection tools:

Then, I will simply Delete the selected components.

Simplify Imported File Technique #2: Create a SpeedPak Configuration

I could also open the .step file with the same options and then create a SpeedPak configuration of the assembly, selecting only the faces needed for mating purposes.

SpeedPak creates a simplified configuration of an assembly without losing references. If you work with very large and complex assemblies, using a SpeedPak configuration can significantly improve performance while working in the assembly and its drawing.

After the file has been loaded right-click in the configuration manager and select Add SpeedPak from the shortcut menu:

Create SpeedPak Configuration simplify imported file

Only external model faces are displayed increasing performance.

Simplify Imported File Technique #3: Create a Part with only exterior faces

Another option could be to simply save the assembly as a part and check the radio button stating show only exterior faces.
