Translating Ops With Surface Geometry

[DeuceNumeroUno]

I am making a c-hook using c# that includes translating the part along the z axis. After translating it, it shows an error when trying to regenerate the ops that use a surface as geometry. 

This is using SelectionManager.SelectAllGeometry and GeometryManipulationManager.TranslateGeometry

[gcode]

Are these solid surfaces, selected by clicking a solid face or faces?

I'm pretty sure such surfaces don't really exist.

They are derived from the solid each time you hit regen... and if they don't exist, you can't translate them

Solid surfaces are store as toolpath entities the way drill points are or chains, they contain parasolid ids for the toolpath api to lookup the geometry,

translating the geometry with a chook call and regenerating the operation should work, however,

 

if the op is using the nethook API, calling .Commit() on the solid could invalidate the associated toolpath entities. Sometime calling Commit(false) solves the issue, however i would recomment using the chook api for advanced operations like unified

in the older versions you could lookup the solid surfaces and other toolpath info by dumping the database

This template contains a c# example of translating geometry using the chook api with an interop dll, which will likely mitigate your issue

Sounds like that could help! Do I need access to the c-hook SDK to be able to view that example? Looks like I don't have permission to view the C++ downloads page on the mastercam website.

yes, you can ask the sdk team for access

My reason for stating this is because..

 

If you import operations from another file that use solid surfaces and select

"Import Geometry", neither the solid nor the solid surface are imported into the new file.

At least that has been my experience.

That's very true, however that's a limitation of the import manager not Mastercams API,

The Nesting Manager can import solids fine

Thank's, as you may have noticed, all I know about Mastercam's API is how to spell it. LOL!

You'd think that with all the effort CNC is putting into using solids to drive toolpaths, they put some effort into making

the Import Manager support solids as well

Seem to still be having the same issue using this method. Unified morph op says the translated geometry is not a surface and going into the parameters and then regenerating the op places the cuts where the geometry was originally. Here is my code:

            var geometryFound = SearchManager.GetGeometry();
            var geoIDs = new List<int>();
            foreach (var entity in geometryFound)
            {
                geoIDs.Add(entity.GetEntityID());
            }
            foreach(var geo in geoIDs)
            {
                Mastercam.IO.Interop.SelectionManager.TranslateSelectedGeometry(geo);
            }

you should use translate_silent

If I'm thinking correctly, the Mastercam.IO.Interop.SelectionManager.TranslateSelectedGeometry is using the translate_silent function.

 

bool SelectionManager::TranslateSelectedGeometry (int geometryId)
    {

    auto spEntity = std::make_unique <ent> ();
    bool succ = false;

    GetEntityByID (geometryId, *spEntity, &succ);

    if (succ)
        succ = MoveEntity (spEntity.get ());

    return succ;
    }

bool SelectionManager::MoveEntity (ent *entity)
    {
    bool succf = false;
    p_3d fpt = entity->u.sld.min;
    p_3d tpt;
    tpt.Set (fpt[0], fpt[1], fpt[2] + 1);
    translate_silent (&entity->eptr, true, 0, fpt, tpt, 1, 1, &succf, true);
    return succf;
    }

#pragma endregion
}

Are you calling Commit() on the solid ay any point?

You will need to eliminate all commit() calls on solids from .net
