Coons Patch

[kathy]

I'm working on the second molded part, and need to replace an imported surface with a Mastercam surface. In the first part, I used a coons patch, but in this part it ain't happening!

Any feedback for creating a coons patch? The geometry is a long, swept angle across an arc, down the side of the channel!

Thanks, Kathy

btw, I ended up using parallel surfacing with c'plane from the side and t'plane from the top. We cut the heck out of a 2x4, but the cuts were good. I'm all for a ftp site. If you could all see the parts i'm working on, it would make a whole lot more sense!

Kathy the pick order in selecting coons patch geometry must be done in the along & across manner.& in some cases i join broken geometry to cut down on the number of picks.

An open FTP site leaves it vulnerable for Warez use.

If Kathy wants to share her file, we'll take these steps:

1. Kathy to upload to ftp.emastercam.com/incoming using FTP software

2. Notify me by email of the file name

3. I'll transfer it to ftp.emastercam.com/Mastercam/Forum

4. A link to the file will be added to the topic

Kathy,

With you part in isometric veiw, you can create 2 coons surfaces. Use coons, auto and pick the the upper left corner first, than pick the bottom right corner and it will autochain. Do the same with the green geometry for 2nd surface. Let me know if this helps.

Yippeeeee!!!!

Bstall,

I clicked, and I clicked, and I clicked... yesterday afternoon with nothing.

After your response, I went back in and clicked, and it worked! I also just upgraded to 8.1 this morning. Would that have been a difference??

I sorta understand coons patch surfacing, but some of this work is trial/ error for me. I've really branched out in the past few months with cplanes, tplanes and all. I can't thank you all enough for all the help!
