Number of SOLIDWORKS Configuration Combinations Calculator

A configuration combinations calculator helps estimate how many possible product variants can be created when several options are combined. In SOLIDWORKS, this is useful when planning configurations, design tables, DriveWorks-style rules, or product families with many selectable choices.

What the calculator means

If a product has multiple independent option groups, the total number of combinations is usually found by multiplying the number of choices in each group. For example, 4 sizes, 3 materials, and 5 colors can produce 4 x 3 x 5, or 60 possible combinations. Add only one more option group with 6 choices and the total becomes 360.

This number is not always the same as the number of SOLIDWORKS configurations you should create. It is a planning number. It shows how quickly a product family grows and helps you decide whether the model should use named configurations, design tables, equations, custom properties, external automation, or a smaller set of released variants.

Why combinations matter in SOLIDWORKS

Configuration counts can grow quickly. A few option groups may look manageable at first, but the total number of possible configurations can become large enough to affect file size, rebuild time, drawings, BOMs, configuration-specific properties, and checking work. A part with 20 configurations may be easy to manage. A product with thousands of theoretical combinations needs a different strategy.

The count also matters for communication. Sales, engineering, purchasing, and manufacturing may all talk about product options differently. A simple combination count makes it easier to see whether every option can be sold, built, documented, and supported.

How to calculate combinations

1. List each independent option group.
2. Count the valid choices in each group.
3. Multiply the choice counts together.
4. Remove combinations that are not physically possible or not offered.
5. Decide how many of the remaining combinations need actual SOLIDWORKS configurations.

For example, suppose a bracket family has 3 lengths, 2 mounting patterns, 4 finishes, and 2 material thicknesses. The starting count is 3 x 2 x 4 x 2, which gives 48 combinations. If one finish is not available with one material thickness, the valid count is lower than 48. The calculator gives the first pass, but engineering rules decide the final usable count.

Do not create every possible configuration automatically

It is tempting to generate every possible combination in a design table, especially when the math looks simple. That is not always a good idea. Many teams only create configurations for common, released, quoted, or sellable combinations. Other combinations can be generated by a controlled model, a form, or a design table when they are actually needed.

Creating too many configurations can make the file harder to open, slower to rebuild, and more difficult to audit. It can also create confusion when drawings or BOMs reference old or unused configurations. Before adding a large table, ask which combinations are real products and which are only theoretical.

Watch for dependent options

The simple multiplication method assumes each option group is independent. Many SOLIDWORKS product families have dependencies. A large size may require a thicker material. A certain hole pattern may only be available on one length. A finish may not be allowed for stainless steel. These rules reduce the number of valid combinations.

For dependent options, calculate the broad count first, then subtract invalid combinations or split the product into smaller option sets. This is often easier to manage than forcing every rule into one large configuration table.

Configuration strategy tips

Use descriptive configuration names when people need to select them manually. Keep custom properties consistent so drawings and BOMs read correctly. For larger product families, consider design tables or configuration publisher tools so option logic is easier to maintain. If the options are part of a sales configurator or quoting workflow, keep SOLIDWORKS aligned with the same rules used outside engineering.

A configuration combinations calculator is most useful before the model becomes crowded. Use it early to estimate complexity, decide which combinations deserve named configurations, and avoid building a SOLIDWORKS file that becomes difficult to maintain later.
