It seems there are more of you who have been assigned a task 😊
I would suggest that you create a small application with a main procedure and a function that removes the redundant points.
In your main procedure you can update the obj for your table with the function. If you use the Selection as the table, you don’t need to ask the user what table to use.
And you can use the Input() function to prompt for the distance tolerance – or just hardcode it.
Remember to set the coordsys too
Use these statements:
First you need to create a loop that runs through all the nodes in your polygon
Use these statements and functions:
For each node in each segment, you will have to create a line between the node before and after, and calculate the distance from the node to this line.
Use these functions and statements:
If the distance is smaller than your tolerance, you need to remove the node.
Use this statement:
You may find the structure of the function OBJRemoveDuplicateNodes from the OBJLib helpful
Also there were some discussions on this topic last week on the MapInfo-L
Good luck – and feel free to come back with additional specific questions

Hello everyone,
How can i write my MapBasic code that erases redundant points along the edges on polygons and prints them to the screen?
