Thanks - I sent you an email.

Thanks Roger. Mastercam 2017.

Hi,

I'm wondering if there is a CHook SDK function that will output a normal vector (or u/v parameter/tangents) for a given input point on a surface. I have looked at calc_surf_unit_norm, however it requires u, v parameters and the tangent vectors as input.

Thanks

Hi,

I've been searching the C-Hook SDK for a rectangular pattern function. I have been able to find the struct for params (SLD_PATTERN_PARAMS) but no function that takes these params as an argument. Do I have to use sld_extrude_from_chain in a control structure to create a pattern?

Thanks

Just checked the linker dependencies one more time and alas - I made a spelling error.

Everything works great now.

Thanks Roger.

After some tinkering, I was able to eliminate the Linker error #1104.

Now I am experiencing a different error:

Error	2	error LNK2001: unresolved external symbol "__declspec(dllimport) char __cdecl sld_extrude_from_chain(struct CHAIN *,struct SLD_EXTRUDE_PARAMS &,int,int *,char *)" (__imp_?sld_extrude_from_chain@@YADPEAUCHAIN@@AEAUSLD_EXTRUDE_PARAMS@@HPEAHPEAD@Z)	C:\Users\johnstonco\documents\visual studio 2013\Projects\CHookWizard3\CHookWizard3\main.obj	CHookWizard3

Yes, the include directory paths are correct.

Hi Roger,

I have tried with Mastercam 2017 and x9. MCGeomSld.lib is included in project dependencies.

Here is the actual linker error:

LINK: fatal error LNK1104: cannot open file 'mcgeomsld.lib'

Here's how I'm using the function:

CHAINS *chains=nullptr;
if (chain_1("Select a chain", &chains)==CHAIN_OK){
  SLD_EXTRUDE_PARAMS params;
  InitExtrudeParams(params);
  result=sld_extrude_from_chain(chains,params,0,nullptr,_T("NewExtrude"));
}

Where the InitExtrudeParams function defines all of the members of params.

Hi,

I have been playing with the C-Hook SDK Introduction examples by Mick George - in particular the SolidExtrusion CHook. I swapped out the DoExtrude() function call in the main method with a call to the TestSolidExtrude function. I am now getting a linker error saying: cannot open file 'mcgeomsld.lib'.

In another application I am using the sld_extrude_from_chain() function and also am running into linker errors. The call in my other application looks identical to Mick's function call.

Any thoughts?

Thanks
