How to trimm or cut a curve

[Mr. Matthias Krueger 0]

Hello,

 

I want to trimm the smaller black circle at the point where the dot is (s. attached picture). Is there a possibilty? Because I need one closed curve to creat a surface later.

Or maybe I can creat a new circle. But I don't know how to get the end angle.

 

Thank you for your help.

Hi Matthias,

 

See the attachment:

 

• Find the intersection between the two curves via intersection point
• Create an image curve and ...
• Use the intersection parameter (via a command) for setting up a subcurve

 

Cheers

HI Matthias,

 

Another option would be to set the start angle of the circle to the corresponding angle which again you can derive from the tangent of the line pointing to(or from) the center of the circle. E.g. yourCircle.setStartAngle(yourline.getTan(2,1)+90) or similar, depending on the orientation of the line and the circle.

 

Cheers

hi sir,
can you please share how to cut or trim surface as i shown in the figure.
thankyou in advance

If you use a BRep, then you can simply trim by any principle axis, see screenshots below.
