Ok Guys, I’ve got a problem with this part. I want to pattern Extrude2 around Extrude1 but nothing I try works like I want it to. I’m going for a “ripple effect” on the outside of my part. Seems this would be a natrual curve driven pattern but like I said - it’s not working for me and I don’t know why not. What am I doing wrong? Thanks

I certainly do seem to have problems with that. I’ll try it through the website.Attachment - toothbrushholder01

Well I took a different approach to the problem this morning and got the curve driven pattern to work. Evidently that command doesn’t work well with ellipses? Regardless I now have a new problem and I know this has to be easy as hell to do but what I want to do is cut extrude the inside out of it. I can shell it but that’s not what I’m after. I want a smooth inside surface (without the pattern) and since I used arcs to construct the initial sketch I want to reuse that existing geometry but the program doesn’t like anything I try to do towards that end.Attachment - toothbrushholder02

Create the shell before adding the grooves.

BTW, in this case the Offset Curve option gives a better result than the Transform Curve option.

Well CBL, I finally got it done. It may not be exactly right as far as the dimensions go but it’s a pretty reasonable facsimile of the real thing. The dome had me scratchin’ my head for awhile but I figured that out too. Thanks for the tips!Attachment - toothbrushholder021

That looks good. I have two suggestions though;
1) Move the Extrude3 feature (bottom recess) above the Shell feature. The bottpm is very thin.
2) As suggested before, use the Offset Curve option (instead of the Transform function) to keep the grooves symmetric around the profile. To see the difference the options make, look at the Top View when changing the options .

Thanks CBL, I took your suggestions and moved the Extrude3 feature above the Shell. I also had noticed that the bottom was thin but hadn’t thought of moving the features around to “fix it”. I also used the Offset Curve option for the CrvPattern - a small difference but it helps. Thanks for your help and suggestions - appreciate it. I’ll learn this damn software yet! Next up - the matching soap dish. Wish me luck.
