845Re: [cc2-dev-l] How to get the selection point of an entity ?

__asm mov pPickPt, edi;
You have to be a bit careful with __asm statements. I often have to turn off optimization for the these parts in the release build.
You might be better off with asking for a point (RD_2DC) and then scan for the selected entity (if any).
You will need the function SetEachPickView() or SetEachPickViewEx(&PickedPt);
Do a DLScan and test interesting entities with if(EPick(pEntRec))
I'm trying to create a command that breaks a line to insert some drawing and I need the coordinates of the selection point.
I wrote a dynamic cursor that stores X and Y in global variables and it works fine except that it doesn't recognise midpoint etc modifiers.
The RDATA.H says that with RD_Pick1 you get the entity at esi and the pk point at edi. I know that esi and edi are ASM registers but am at a loss at how to retrieve the info with C++.
Thanks for any help...
