CATIA - Import and process ASC files
There are many complicated file formats for reading and writing 3D mesh data. However, if you work only with 3D points in your 3D geometry application, then the ASC file format is a convenient way to read, write and display point data. ASC stands for ASCII and the files have an extension of .asc. This is a text file format, where each line has the XYZ coordinates of one point, each coordinate separated by whitespace.
CATIA V5 can process ASC files, but it does require a lot of time!

Step 1: Import and process ASC files
Here are the steps on how to import and process ASC files in CATIA V5:
- Import the ASC file into CATIA V5. To do this, go to the File menu and select Import. In the Import Files dialog box, select the ASC file and click Open.
- The ASC file is imported as a point cloud. To process the point cloud, go to the Part Design workbench and click on the Create tab. In the Point Clouds group, select the appropriate command.
- In the Create Point Cloud dialog box, select the point cloud that you want to process. Click OK to process the point cloud.
The following are some of the commands that you can use to process ASC files in CATIA V5:
- Create Point Cloud - This command creates a point cloud from the selected ASC file.
- Filter Point Cloud - This command allows you to filter the points in the point cloud based on their properties, such as their X, Y, or Z coordinates.
- Smooth Point Cloud - This command smoothes the points in the point cloud.
- Resample Point Cloud - This command resamples the points in the point cloud, reducing the number of points.
- Create Surface from Point Cloud - This command creates a surface from the selected point cloud.
