How to get info on machine groups and operations from the SDK.

[CaKiwi]

Hi everyone,

 

I have the following SDK questions:

 

1. Each operation listed in the toolpath manager has a description associated with it. How do I access these descriptions from the SDK?

 

2. To get a list of all operations in the current model, I can call

 

list_manager(OP_ID, "", LSTMGR_GET, (void **)&operaThis);

 

How can I get a list of all machine groups in the current model?

 

3. How can I tell which machine group an operation is associated with or how can I get a list of all the operations associated with a machine group?

 

4. How do I access the description of a machine group

 

Thanks in advance.

I'm assuming you're asking about op.comment.

Looks like the list_manager() function isn't used to get machine group data in X. I haven't played with the groups in X yet, so I'm of no help here. Did you find anything in Groups_CH.h that might help? I'm also of little help for questions 3 and 4. Hopefully someone else can help.

Hi Bullines,

 

Thanks for the response.

 

I had looked at op.comment but it does not seem to hold the description of the operation. For example, if I load the sample part contour-shallow - add cuts.mcx, it has 3 operations shown in the Operations Manager each of which has a description associated with it ("Without - Shallow", "Shallow - Add Cuts" and Alt - Floor Toolpath"). But the op.comment field for each is empty.

 

I will look some more in groups_ch.h to see what I can find for my machine group questions.

 

Thanks again.

There is group_list structure defined in the file groups_ch.h as well as some routines for manipulating group lists but I cannot see any routine for getting the list of machine groups.

 

Any assistance would be greatly appreciated

I would also like to know about this.

The only thing I have come up with so far is the grp_idn field in the cmn structure of the op structure of the op_list structure. I have a model with 2 machine groups, the first containing 3 operations and the second containing 1 operation. When I step through the operation list, the grp_idn field has values 2, 3, 4 and 6 respectively for each of the 4 operations. I am surmising that the 2 machine groups are in slots 1 and 5 and that when this number jumps by 2 we have started a new machine group. If this is all true (I need to try it out on a few more models), I at least know which operations are in which machine groups. If anyone has any better ideas, I would love to hear from them.

I've found that if I call the routine GroupsMachineGroup with a NULL argument I get an arbitrary member of a list containing all the machine groups and operations and I can then get to the head of the list by following the head_ptr of this member. Calling it with a member of that list returns the machine group of that member. The following code finds the machine groups in the list.

 

code:

---

int idn;

group_list *pGroup1, *pGroup2;

pGroup1 = GroupsMachineGroup (NULL);

pGroup1 = pGroup1->head_ptr;

//printf("%s - %s", pGroup1->name, pGroup1->ogi.pg1.comment);

idn = pGroup1->grp_idn;

pGroup2 = pGroup1->next_ptr;

while (pGroup2 != NULL)

{

do

{

pGroup2 = pGroup2->next_ptr;

if (pGroup2 == NULL)

{

break;

}

pGroup1 = GroupsMachineGroup (pGroup2);

} while (idn == pGroup1->grp_idn);

if (pGroup2 != NULL)

{

//printf("%s - %s", pGroup1->name, pGroup1->ogi.pg1.comment);

idn = pGroup1->grp_idn;

}

}

I've also found a routine GetMachineList() but I've had a problem linking with it. I'll let you know if this provides a simpler solution.

Kewl Keep it up

Add

code:

---

  extern DllImpExp group_list * group_list_ptr;

---

and you can access the pointer directly.
