How to hide lines on an arc?

[Anonymous]

HI! How can I hide the line on the arc when I use the PYRAMID command? I have tried to modify various parameters and failed.

This works if you want to keep it as a pyramid, but maybe there are other solution with RULED or SWEEP?

Add a 'fake' node before the curve (as close as you can get it), then change the status of the curve edges.

Thank you for your method, I converted the arc into a line.

Yes with many straight lines you can control their visibility (status) individually.
Just make sure you have enough lines for a smooth looking curve.
With an ARC you can just change the RESOLution value to increase/decrease the number of segments.
