Kind of hard to explain.... when you make shapes with alot of sides (sphere cylinder etc.) if you move it then the lines get all messed up and the faces are all over the place
does this only happen to me?

Maybe you made it invalid.

no it happens alot... ill get pics up eventually i make the object then if i move it or duplicate it or anything it gets all messed up hopefully ill have screenshots up by tomorrow

Rotating can cause this effect. I tend to use snap-to-15-degrees option and usually rotate exact amounts like 90 degrees. This keeps and object aligned, but if you were to rotate a odd amount it'll tend to much things up. The other way to break objects up is to resize. Again, if you resize, try to evenly resize the sides by using the corner helpers. Moving an object shouldn't cause that much of an issue.

it shouldn't but it did...idk i tried to recreate it but i couldnt it seems to only happen for a certain size maybe? i think it was 56 all around but im not sure
the reason i need the spheres are for cannonballs for a cannon i made it is supposed to go up and down to 5 different angles and shoot but i cant make it move any ideas?

I stumbled across this today while looking for something else developer.valvesoftware.com/wiki/Hammer_Carve_Command_Usage#.22Do_not_carve.22 Just incase anyone is too lazy to go there this is what it says "Complicated Shapes Some brushes may appear to be valid yet will change after saving and reloading the map or running the clip plane tool. The reason is because the map file describes solids as a set of planes rather than as a set of vertices. A plane, by definition, is a flat surface extending to infinity in all directions. When Hammer reads the map file, it finds the places where three planes intersect and creates vertices at those locations. (This is why concave brushes are impossible.) The issue is that the numbers used to describe planes and vertices have a limited number of decimal points. Although the vertices may lie perfectly on the grid when a brush is created, the resulting planes may have many decimal places. If the decimal limit is reached, the planes will be slightly different. For complicated shapes such as spheres, this can generate an invalid brush very easily. Shapes with such issues may develop visible seams along the edges where it is possible to see through the brush." Makes sense to me

Interesting! Nice find

The reason it goes all horrible like that is because all of the corners must be on the grid once compiled. This results in not so spherical balls. To fix this, make the sphere and don't resize it.
The reason I tell people not to use the carve tool is because... *deep breath* ...if you have to ask, you're not going to be able to use it properly.
Perhaps it's a good topic to make a video on...

I think that this topic is more about resizing complex shapes, resulting in problems following the grid.

But do you see how many more brushes are created and how messy it is?

Here is an example that I ran into, that has nothing to do with resizing, or carving. The 'BEFORE' images were from work done entirely with the vertex tool, painstaking making sure that everything snapped to grid. (grid setting of 8) I saved the file, closed hammer, reopened hammer, loaded the file, and the result is the 'AFTER' images. No compiling, moving, resizing or other fiddling in any way. I know, because I thought I screwed up the first time, and manually fixed every vertex that was off grid, and tried again. Same result.

By chance does your shape you made have any concave surfaces? Because these would automatically reload the vertexes into different locations to remove them.
Try making your shape out of two blocks instead of one.

Yup, that must be the case, bending a face in two planes at the same time. I guess I am too accustomed to thinking of faces as made of triangular polygons that can be tweaked individually.
