When drawing a H-beam, the section preview is shown below:
As you can see, on one side of the web, the starting and ending points of the corner R form a θ angle of 90° with the circle center.
The image below illustrates the difference:
θ-related parameters are not available in the Draw Part. The web toolpath endpoint of drawn or imported parts is managed in:
User Preference Settings → User Preference (scroll down to Other) → H-Beam toolpath angle.
If parts have already been imported, even deleting all parts does not restore access to this setting. You must click New in the top-left corner before adjusting the setting in the User Preference Settings.
When θ exceeds the set limit, the system automatically whitens (not processed) that section of the toolpath to ensure safety. Here is a typical case.
Use the Optimize H-Beam Web Toolpath function to set this automatically.

After Optimization:
If the R size of the I-beam does not match the drawing exactly, and you want to shorten the web toolpath at corner R to avoid collisions during cutting, you can reduce the θ angle slightly.
Modifying this value is generally not recommended unless necessary.
After making changes, reset the value to default before reopening the software to prevent unintended toolpath issues in future operations.
This setting applies to all parts, so ensure that all parts in a batch are compatible with the adjustment.
The values in the image are for reference only; adjust based on actual conditions.
