Your data has separate blocks for the airfoil and other components, so showing just the airfoil is pretty easy. There are a couple of options.

## Tell ParaView to not draw the body

Select the reader in the `Pipeline Browser` and open the `MultiBlock Inspector` (under the `View` menu). Uncheck all the blocks you do not want to see (everything except `airfoil` in your case).

## Create a new dataset containing only the blocks you want to see

Select the reader in the `Pipeline Browser` and then add the `Extract Block` filter ![Screenshot 2024-02-06 at 1.17.55 PM](https://discourse.paraview.org/uploads/default/original/2X/c/cd65ea4e32403cfc4b87ce9b46c2de34cd9af333.png). Uncheck all the blocks you do not want to see (everything except `airfoil` in your case) and click `Apply`.

This will create a new data set containing only the blocks you want to see. Even though yopu have added a new dataset, it does not take any more memory. The memory is shared with the source, so you don’t have to hold the blocks multiple times.
