Change level

[Jure Klemencic from Camincam]

Hi,

 

this must be a very simple question for programming in C# API 1.0: how to move all the objects to a given Level x?

This is how I started:

code:

---

 Mastercam.GUI.SelectAll(); 

---

Now what?

 

Thanks.

I'm certainly not an expert (or even very knowledgeable ) on this older (v1.0) NETHook API.

 

This seems to work ->

 

code:

---

/// <summary>

/// ChangeLevels

/// Moves the currently 'selected' (Point, Line, Arc) entities to the specified level.

/// </summary>

/// <param name="level"></param>

public void ChangeLevels(int level)

{

bool ok = true;

int found_id = -1;

 

// Only look at 'selected' items

MC_SELBIT selMask = MC_SELBIT.Select;

 

// The 'type(s)' of entities to search for in the database

MC_ENTMASK entMask = MC_ENTMASK.Point_ID | MC_ENTMASK.Line_ID | MC_ENTMASK.Arc_ID;

 

// Start at the beginning

int start_id = Mastercam.DataBase.GetDBStart();

do

{

ok = Mastercam.DataBase.DBSearch(ref start_id, ref found_id, selMask, entMask);

if (ok)

{

CEntRef eRef = new CEntRef(found_id); // Reference to the Entity

eRef.level = level; // Set the level to...

}

} while (ok);

}

Roger, thank you very much.

 

Today I remembered that some time ago I was able to program code like this, but then I forgot a little...

 

Your code works well. But the way you get the references to all entities seems a little odd to me. I've done it in an other (also odd way:

code:

---

public static int[] AllEntities()

{

CEntRef[] entList;

int eptr;

int[] allEnts = new int[10000];

int i = 0;

int[] levels = Levels.GetVisibleLevels();

foreach (int level in levels)

{

entList = Levels.GetLevelEnts(level);

foreach (CEntRef ent in entList)

{

eptr = ent.eptr;

allEnts

= eptr;

i++;

}

}

return allEnts;

}

---

I'll appreciate any comments to my code.

Jure,

The difference in the methods is probably because of the way the problem is approached.

You stated you want to change the levels of the selected entities.

So, how to do that? I (not knowing how!) thought...

“I want to go thru the database, retrieving just the selected entities and change the level of each of those entities.”

If there was a method to load up the CEntRef[] entList array with all the currently selected entities, your use the foreach would be an elegant solution. But, a built-in method that does that does not exist. ;(

(At least I don't think one exists. I did state that I'm not very experienced in using the NETHook v1.0 API)

Therefore you see my solution to "walk" thru the database.

 

As for using a modified version of your method, to solve the “change levels” problem.

If you wanted to “move” all of the entities on the Visible Levels to a new level, you could do something like shown below.

*Note how the the "problem" has been restated!

code:

---

       /// Change the level of all the entities on all the currently visible levels

public void ChangeLevels(int newLevel)

{

int[] levels = Levels.GetVisibleLevels();

foreach (int level in levels)

{

CEntRef[] entList = Levels.GetLevelEnts(level);

foreach (CEntRef ent in entList)

{

ent.level = newLevel;

}

}

}

Roger,

 

thanks for your generous comments.
