SOLIDWORKS – Creating Internal Volume – Combine (Subtract)

EmailFacebookLinkedInTwitterShare

Previously there have been a few CATI blogs written regarding the process of finding the internal volume of a part. Such methods include the commonly known Intersect command to achieve this task as well as the Delete Face command. This blog will touch on one more approach to that end goal which might prove useful to your circumstance. An alternative approach to identifying the internal volume of a part in SOLIDWORKS is by use of the Combine feature, specifically Combine […]

In this blog, I will describe how to create an internal volume of a part using the delete face command as an alternative to the intersect command. An alternate method is sometimes needed in cases where the intersect method fails and there may not be time to troubleshoot, so a manual method is needed. Initially it may be difficult to understand why deleting faces can help create an internal volume, but it does one key thing for us: it separates […]

One of the key functionalities of the ‘Intersect’ command is to create geometry using an enclosed volume. This is a simple method for finding the internal volume of complex parts, the first step is to cap all inlets and outlets that lead to the internal volume: If your various inlets and outlets are planar, you can use the ‘planar surface’ command to cap that opening. There can be multiple openings assigned to a single ‘planar surface’ command. Additionally, if you […]
