Changing existing Radius Form ?

oliver_berger

Hello all

i am really bad with CAD, but i managed to draw a grip for a wheel a while ago. After 3D Printing and testing, i have to change the outside radius, to make it more round like the inside of the grip.
Sadly i can't figure it out how i can change it. Not sure if i have somehow first to add more material to it.
Or do i have to start from scratch ?
Not sure if i have to link my drawings or if you can find it.

Maybe someone can get me some directions.

Thanks

lana

Would this work ? https://cad.onshape.com/documents/5470abb4c32f28f9d3be0aab/w/3038949f539bf1924fb99cae/e/86264e14dbb52475e209c13e

Yes that is exactly what i wanted to do ! Looking at all the steps you did, i never would have guessed them. Guess it is too complicated to explain them to a CAD Noob like me ? CAD sometimes is really hard to understand as a beginner which only uses it for some hobby 3d printing projects. But really satisfying when i finally found out how to draw something i wanted.

Hi Oliver,

Sometimes it is easier to just do something in the product than explain it in words (and this one was pretty complicated).  Since Lana's copy of the document is public, you can press "make a copy" at the top to copy it back to yourself.  Once you have it copied back to yourself, You can use the rollback bar to step through each of the operations Lana did and see how the new part developed:

search for "rollback" on these help pages

It also may be helpful to hide your original part by pressing the eye next to "Part 1" in the parts list and to make the new part opaque using the appearance editor:

In general, these direct modeling operations on an imported model have a steeper learning curve than modeling from scratch and @lana is a CAD expert so don't expect to be able to do this on day 1.  Hopefully you can learn something new by going through her steps, or by watching some of our videos!

I will do that tomorrow ! Thanks a lot for the help to you all.
