MdlLineString_create(dgnBuf, NULL, lsPoints, (ntmpcount+1)) Int LineStringDynamics(Dpoint3d *ptP,int view) If this function is not defined then user will be able to give a point //in the map as usual but will not see how his linestring is appearing //in the map at the runtime. Dynamic display function, it is passed a cursor coordinate as the //cursor moves in the map Void LS_Complete(Dpoint3d *point,int numView) Void LS_NextPoint(Dpoint3d *point,int numView) function definitions – if not added then it will not compile number of vertices to create a final linestring

number of vertices for the dynamic display of the linestring maximum 101 vertices – This is an array of coordinates The user will be also see the rubber band dynamic display of the linestring as he gives point. When user gives a right-click, the linestring placement will complete and a linestring will be generated. In the program a prompt will ask use to give a point, when user gives a point in the view, an array of points will be populated and a counter of the number of vertices will be maintained. The code is simple and self-explanatory but I will still add some description for you to understand. How to initiate a function on the right-click (Reset)Ĥ. How to initiate a function on a data clickģ. Remember that this code is only applicable to the older version (Microstation/J – version 7).Ģ. We will place a line string through a MDL program. Today we will do a simple program which will explain you a number of things in MDL programming in a simplified manner.
