C++ Toolkit - Get ProView Points/Vertexes

C++ Toolkit - Get ProView Points/Vertexes

Hello everyone.

I trying to put some dimensions automatically on a 2D drawing. I don't want that this dimensions cames from the 3D Model. I want to create directly on the drawing.

For that, i need to know some entities of the drawing, so i can give the attachments to the function ProDrawingDimCreate().

I need to know if you guys, know some way to visit entities like ProPoints or ProEdges of a specific ProView.

What do you suggest?


Many Thanks.

Re: C++ Toolkit - Get ProView Points/Vertexes

I did a similar project years ago. It was a CAD/CAM automation system written in ToolKit and API (in C#).  

Auto-dimension was included for the key feature location, implemented in C#. 

Here is My some samples code in C#. 

Hope this help

 

public bool CreateAxisPosiontDimension(TaskData task,string CsysName, string ViewName, string ParamName, string ParamValue,double PlateWidth)
{
IpfcSelection csysSelection,PointSelection;
IpfcModelItem item;
IpfcView2D selView=null;
IpfcView2Ds views;
CpfcPoint3D SelPosition;
IpfcModelItems Points;
CpfcPoint3D csysPosition,pointPisition;
IpfcTransform3D viewTransform;
CpfcVector2D Csys3DPosition,dimPosition;
IpfcOutline3D outline;

Many thanks for your help.

I will check your solution and use it in my problem.

 

Best regards.
