When you have a new installation of SOLIDWORKS on your system you may notice that there are very few Profiles available in Weldments when you select a Structural Member.
The reason that SOLIDWORKS have not included all the standards and profiles in the standard installation is due to the size of the installation. That is why SOLIDWORKS provides you with a free download link in case you require other standards or profiles.
How to Download SOLIDWORKS Weldment Profiles
To access all of the standard profiles are available in SOLIDWORKS go to the SOLIDWORKS Task Pane and select the Design Library tab. From there expand the SOLIDWORKS Content > Weldments folder as shown below and it lists all the Standards that are available for download.
To download a particular standard click on it while holding the Ctrl (Control) key on your keyboard. You can download the file and save it at any location.
Once the downloading process is finished you can unzip the file. Now you need to place the unzipped files in the right location. Run SOLIDWORKS and go to Tools > Options and select the File Location from the System Options tab. In the File location select the Weldment Profiles option from the pull down menu. It also shows the default location of the Weldment profiles.
Now open your Windows Explorer and go to the location shown for Weldment profiles from the system options menu, then copy and paste the unzipped file as shown below.
Once you are done with the above step you will see the profiles for that standard. In this case we copied the ANSI Inch and now there are new types of profiles as shown below. After this all the profiles will automatically appear in the Structural member menu in the Weldments toolbar.
