Picking a WCS

[CaKiwi]

Is it possible to allow the user to pick a WCS from the screen?

 

Alternatively, is there a way to get a list of the names of all WCS's in the model along with their matrix values?

 

Thanks

I think you need NamedViews/named_view_manager.

 

code:

---

 

#define VIEWARRAY CArray <view_ent, view_ent> ///< Array of view_ents

 

extern DllImpExp VIEWARRAY NamedViews; ///< Current array of named views

extern DllImpExp CArray <view_icon, view_icon> NamedViewIcons; ///< Current array of named view icons

extern DllImpExp MC_BOOL SetOriginOnSaveNewViewDlg; ///< Specifies whether to set the cplane or tplane origin when this new view is selected for use as a cplane or tplane

 

 

/**

*

* @par Purpose:

* function to add/get/delete/edit named views in the current db

*

* @param[in,out] vwp pointer to named view entity

* @param[in] mode VWMGR_ADD, VWMGR_RENAME, etc.

* @param[in] new_name new view name (for VWMGR_RENAME only) or "" (null string)

* @param[out] succf TRUE = view manager successful

*

*/

DllImpExp void named_view_manager (

view_ent *vwp,

short mode,

char *new_name,

MC_BOOL *succf);

Thanks for the response Takashi. I'm sorry I haven't got back to you sooner but I have been working on other problems.

 

I have experimented with using named_view_manager and found the using VWMGR_SELECT for the mode argument allows the user to select a view. However, the view structure returned has an m field which gives the X, Y and Z rotation of the view but does not contain the origin of the view. Is there a way to get this information?

 

Thanks

CaKiwi,

 

View Origin... World or View ?

 

In the view_ent struct there is this member ->

 

assoc_pt pts[4]; //< [0]=origin, [1]-[3] orientation all in world coordinates

 

This [0]=origin struck me as something I should look into.

 

Looking at the View info (via the View manager in Mastercam) I see this data ->

 

code:

---

View Id #       : 8

Name : NEW VIEW [8]

Comment :

Origin : X-0.36120188 Y-0.68597797 Z0.

Number : 20

Matrix : X0.36822397 Y-0.89244705 Z-0.26067102

: X-0.89244705 Y-0.26067102 Z-0.36822397

: X0.26067102 Y0.36822397 Z-0.89244705

Associative : Yes

pts[0]: ent_idn 11 , eptr 149716256 , method E

pts[1]: ent_idn 11 , eptr 149716256 , method E

pts[2]: ent_idn 9 , eptr 149716192 , method E

Color : 10

Used in toolpath : No

---

But when I looked at the X,Y,Z data in pt[0] of the view_ent I had these values ->

0.47919581977711789

0.50116812077418260

0.34674839070776653

 

Hmmm...

Doesn't match up with -> Origin : X-0.36120188 Y-0.68597797 Z0.

 

But wait!

In View Manager where is lists the Origin it says -> Origin (in View Coordinates)

 

I added this command to my code -> world_to_view (v.pts[0].pt, v.view_n, vpt);

and out comes the Origin values I was looking for in vpt.

 

Sweet!

 

code:

---

MC_BOOL MySelectView()

{

view_ent v;

MC_BOOL succf;

p_3d vpt;

named_view_manager(&v, VWMGR_SELECT, "", &succf);

world_to_view (v.pts[0].pt, v.view_n, vpt);

// vpt now contains the View Origin (in View Coordinates)

return succf;

}

Thanks for the help, Roger. It is working well for me

I try to make a plane to 100mm from TOP, what I miss?

code:

---

 		MC_BOOL succf;

ent e;

view_ent vEnt;

memset(&vEnt,0,sizeof(view_ent));

DB_LIST_ENT_PTR e_ptr;

p_3d TempP;

assoc_pt origin, xaxis, yaxis, zaxis;

char neveme = NULL;

 

TempP[0]=100, TempP[1]=0, TempP[2]=0; // Origin

copy_p_3d(origin.pt, TempP);

TempP[0]=110, TempP[1]=0, TempP[2]=0; // Xaxis

copy_p_3d(xaxis.pt, TempP);

TempP[0]=100, TempP[1]=10, TempP[2]=0; // Yaxis

copy_p_3d(yaxis.pt, TempP);

TempP[0]=100, TempP[1]=0, TempP[2]=10; // Zaxis

copy_p_3d(zaxis.pt, TempP);

 

vEnt.color = 12;

memcpy(vEnt.comment, "Plane - 100mm", 256*sizeof(char));

vEnt.rel_type = VREL_TOP;

vEnt.vw_method = VM_3PTS;

vEnt.type = -1;

vEnt.assoc = false;

vEnt.used_in_op = false;

vEnt.set_origin = false;

memcpy(vEnt.vname, "SZUKA", 41*sizeof(char));

vEnt.woff_n = 2;

vEnt.display = 1;

vEnt.pts[0] = origin;

vEnt.pts[1] = xaxis;

vEnt.pts[2] = yaxis;

vEnt.pts[3] = zaxis;

store_ent(&e, &e_ptr, 0, e.color, e.level, e.a, &succf);

named_view_manager(&vEnt, VWMGR_ADD, &neveme, &succf);

---

BTW, how can I rotate & save a plane?

Thanxx for any help & advice!

I assumed that '100mm from TOP' meant the you wanted the origin to be X0,Y0,Z100

 

Original code:

origin.pt is not correct => X100, Y0, Z0

and

The Matrix for the view is not defined

 

Get you this ->

 

code:

---

View Id #           : 8

Name : SZUKA

Comment : Plane - 100mm

Origin : X0. Y0. Z0.

Number : 19

Matrix : X0. Y0. Z0.

: X0. Y0. Z0.

: X0. Y0. Z0.

Associative : No

Color : 12

Used in toolpath : No

---

Corrected code:

 

changed:

TempP[0]=0, TempP[1]=0, TempP[2]=100; // Origin

 

and added:

 

// This is TOP view matrix...

// typedef p_3d matrix_33 [3]; ///< 3x3 matrix

vEnt.m[0][X] = 1;

vEnt.m[0][Y] = 0;

vEnt.m[0][Z] = 0;

 

vEnt.m[1][X] = 0;

vEnt.m[1][Y] = 1;

vEnt.m[1][Z] = 0;

 

vEnt.m[2][X] = 0;

vEnt.m[2][Y] = 0;

vEnt.m[2][Z] = 1;

 

origin.pt => X0, Y0, Z100

and

The with a proper Matrix

 

code:

---

View Id #           : 8

Name : SZUKA

Comment : Plane - 100mm

Origin : X0. Y0. Z100.

Number : 1

Matrix : X1. Y0. Z0.

: X0. Y1. Z0.

: X0. Y0. Z1.

Associative : No

Color : 12

Used in toolpath : No

---

Or you could something like this ->

 

code:

---

// Load a view_ent with the data from the specified view#

MC_BOOL GetView(view_ent *view, int view_n)

{

MC_BOOL succf;

memset (view, 0, sizeof (view_ent));

view->v_idn = view_n;

named_view_manager(view, VWMGR_GET, _T(""), &succf);

return succf;

}

 

// Make a new view based on an existing view

MC_BOOL MakeView()

{

view_ent vEnt;

memset(&vEnt,0,sizeof(view_ent));

int view_n = 1; // TOP

MC_BOOL succf = GetView(&vEnt, view_n);

if (succf)

{

vEnt.v_idn = 0; // So VWMGR_ADD will auto make a new id#

 

// Set what you want different than the original View

vEnt.assoc = false;

vEnt.used_in_op = false;

vEnt.set_origin = false;

memcpy(vEnt.vname, "SZUKA", 41*sizeof(char));

vEnt.woff_n = 2;

vEnt.display = 1;

vEnt.color = 12;

memcpy(vEnt.comment, "Plane - 100mm", 256*sizeof(char));

 

// Set the Origin Pt

vEnt.pts[0].pt[X] = 0.0;

vEnt.pts[0].pt[Y] = 0.0;

vEnt.pts[0].pt[Z] = 100.0;

 

named_view_manager(&vEnt, VWMGR_ADD, _T(""), &succf);

}

return succf;

}

*** BTW, how can I rotate & save a plane? ***

 

You want to crate a new View that is rotated from another (original) view ?

[Peter - Avivi CNC Solutions]

Thank you Roger!

It's explained well!

Yes, exactly. From TOP. Use matrix again?

[Peter - Avivi CNC Solutions]

Up...

[Roger Martin from CNC Software]

What input to you plan to use to rotate the 'original' view to create the 'new' view?

 

1> A 3x3 matrix

2> A rotation angle - about X,Y and/or Z

Like the 'Rotate View' dialog takes in.

[Peter - Avivi CNC Solutions]

Roger, the plan is angle, about X and/or Y axis.

Yes, like in the "Rotate View"

 

Many Thanxx!

Hi,
unfortunatly i can't get the list of all names of WCS's under 2017 no more?
Neither the

extern DllImpExp VIEWARRAY NamedViews; ///< Current array of named views

nor the named_view_manager(...) worked for me.
How can we get the mentioned list of WCS's under 2017/2018?

Thanks in advance

[CNCLaundry]

found it and the solution is
extern DllImpExp MastercamPlanes Planes;
