Some defects after extrude

Post by MrCedric »

Hello :)

Happy to find your tool and a totally newbie on it :oops:
Like I mention in the title I made an extrude from a SVG imported, but the result has some weird faces :o . I don't understand why.
I hope you could help me, please find below the screen capture below :

Hi and welcome to the forum!

This is probably only a visual defect. You can decrease in the View attributes the values for AngularDeflection and Deviation - at the cost of more rendering time and a less responsive display.

Yes it seems that there is no reason to have this strange polygon.
I hope you are right, because the price for the cnc cut is not low :roll:
I have tried to find a way to change the view attributes but impossible :oops: :oops: :oops:

Right click in the Properties panel and select "Show all" or whatever the translation might be. Then added options will be available.

Experiment with Angular Def and Deviation. You can upload your file and I'll do some experimenting on it if you like.

Drag/drop onto the form where you type your reply is the easiest way.

It are indeed the named attributes:
- select the body
- switch to the View tab at the bottom
- change the value of Deviation to 0.01

Looks perfect here:
