cutting from the inside part of an object?
Hi All,
Have worked out how to cut bits objects away, however I can't see the simple way to cut away an outer edge. so say you have a square block and you want a round cut along one side, I can do it if its like so )_| but how do you do like this (_| the round bit begin on the edge. I think you call it quarter bead. |

Re: cutting from the inside part of an object?
Hmmm. Easiest way is probably to make a cylinder, cut away half. Make a divided cube--so you have points in the middle to join the cylinder center vertices to--and remove one face of the cube. Then merge them together. You can use Snap Vertices by Distance with a small distance to merge the points together so you don't have to snap them by hand.
That will give you something like this: |

Re: cutting from the inside part of an object?
Thanks again Lisa, so the long way is the only way, be nice if they could make a cut inside out function, not that I would see much use for it except for doing this.
found a site that had some objects to practice making so been trying ways to build them, plus getting my head around how the features work. cheers. |

Anytime!
Yeah, you might be able to do it with the boolean tools on the object menu, too, but I don't think you'd get as clean geometry in the end. |

Another way to do it is make a cylinder, select half of it,(red) extrude along normal, delete the surfaces you dont need,(red) selct the vertices counterclockwise and do a crtl+shift+s to create a ordered surface.(green)

Re: cutting from the inside part of an object?
I think my description of what I am trying to do is going of course
I am trying to cut the top and bottom curve of this object from a box. |

Would be easier to build the full curve and cut off the box section.

Re: cutting from the inside part of an object?
Anyone know a good web site where you can find simple objects to practice making that teaches you how to do those shapes?

Re: cutting from the inside part of an object?
Hmmm. I don't know of any sites off the top of my head, but I bet some college drafting classes might, and a lot of college classes put their materials online. I remember making odd shapes like that a lot in drafting class, although the class I took was pencil-and-paper.
For what it's worth, here's a quick video of how I'd tackle it: http://independentdeveloper.com/files/makecurve.wmv |

Re: cutting from the inside part of an object?
Thank you Lisa,
That video is very informative , have seen in a few seconds where I have be going wrong doing something else, I see its a bit of working out what the shape is then pull or pushing bit afterwards. Now try out following it as it played . edit been watching the video and I am a bit lost on how you are getting the vectors into a straight line. I see when you drag over them, they turn green, what I can't make out is do you press a key to line them up or what, can't get it to do that bit. cheers Last edited by HowDo; 8th August 2008 at 03:54 PM. |
