- I believe you can achieve your goal if you consider working with Configurations.
- Setup each configuration to be specific to one Airfoil
- Then enable the respective configurations when willing to work on each Airfoil
Step 1: "CONFIGURATION NAME1" is "NACA 2412" and import all the XYZ curves related to this Airfoil (Say 2 of them)
Step 2: "CONFIGURATION NAME2" is "NACA 2418" and import all the XYZ curves related to this Airfoil (Say 2 of them)
You can specify the Curves for each configuration as below.
First of all Import the Curves into Solidworks (say 4 of them; 2 for each Configuration)
Then Right click on each curve and select the Configuration Names where it has to be Suppressed as shown in below screenshot.
Select the Checkbox to configure where the selected curve has to be Suppressed;
Below Curve 1 is Enabled for only CONFIG1 Configuration, hence it is Suppressed in CONFIG2
So in your Case, You will have 2 curves in each Configuration which you would be using in Loft Feature.
Hope this helps.
