editing a solid

[notso]

I've got a parasolid that I've imported from UG and it turns out that I need to move a few holes around (threaded holes). When I try to select a hole to translate it (using "window tool") it doesn't move all of the geometry associated with the hole. Can any of you tell me what I'm doing wrong?

 

Thanks

What exactly is it not moving? Edge Curves, or an actual hole?

Try importing the solid with the Edge Curves checked off. Than run the Find Features option in solids. Try moving it now.

[robk]

Also don't forget to regenerate the solid afterwards

Hi Notso, AS robk said,

When you import a parasolid body in mastercam, it comes as dumb solid, i.e. there is no history tree. The arcs and lines created on the edge are not associated with the solid. If you want to move ahole in it do as follows.

Solid--»next menu--»form feature

select hole.

It will create new arcs at the edge of holes and extrude cut operation in history tree. These new arcs are now associated with the solid body. If you move them and then regenerate the solid it should change as per your requirement.

Good Day notso,

 

 

Do you have solids??

I dont think UG brings in history tree for solids.

 

You might be moving the edges and not the surface/

solid.

Thanks for the quick replys. After messing around w/ the different levels, I think I was only moving edges and not doing anything to the solid. I'll mess w/ it some more and let you know how it turned out.

Good Eve,

 

 

You need solids add-on in order to edit a solid.

 

If you move the hole, you can still use that

geometry for chaining or a drill geometry.

 

 

The best way is to have the hole moved in UG

and then (Import parasolid and )use the good geometry.

Cadist,

I don't have "form feature" as an option under solids-->next menu. I just have "find feature". I guess I should have mentioned that I'm doing this in Lathe level 1 w/ solids.

Sorry slip of tongue .. I mean slip of finger. teh mixed mc with ug.

Use find feature and let me know the result.

Cadist meant 'Find feature'.

 

You would then select Holes on the dialog box. This will create the edge geometry to 'cut' the feature. You can then move this geometry and regen the Solid.

[notso]

when I used the "find feature" and regened the solid, I still had stuff left at the original location. I also need to change the length and dia of a boss on the part. Any ideas on this?

[cadist]

Will you be more specific sir, which feature you actually wanted to generate. And what was left. If possible leave your file on ftp some one will definitely do it.

As far as boss part is concern find feature can not convert that.

You may have what they call a dumb solid. A dumb sold is still workable. Since you have the the edge curve it is still easy. use the edge curve and create a solid and add the body to close the whole. Move the geo into a new place with copy. Then cut another hole where the new one is.

notso,

 

There are several things you can do with the solid, even as a "dumb body" imported from UG. medaq gives some good advice, as well as Steve Biehl, and others. An imported solid is just referred to as a "brick". You can still perform other solid features to this solid. For Mastercam to work properly with solids, you need good, closed 2-D geometry for adding to, or cutting, a solid body. Once the solid feature has been added, or cut, to the solid "brick", the geometry is associated with that feature. Move the geometry and regenerate the solid and you will have a new solid shape. That's the beauty of Solids. "Find Features" is just another way to generate solid features on a "brick" without doing it all manually. HTH

Thanks for all of the input guys. I just ended up drawing the geom from scratch (not too complex). I will mess around with editing the imported solid again when I get more time.
