HI,

every line which you need to delete is inside the block. So what you need to do that is you have to select a line and a block and find out whether that line starting and end point inside of a block or not. if it is then you can delete that line. to find the algorithm and you can go through below link

I'm trying to work out how to do this too. was hoping there would be some simple code on a past solution i could copy. I don't know the answer, but this will help you, i think:

This is the .net Developer's guide. IT is your friend:

http://docs.autodesk.com/ACD/2010/ENU/AutoCAD%20.NET%20Developer's%20Guide/index.html?url=WS73099cc142f48755-5c83e7b1120018de8c0-22be.htm,topicNumber=d0e2452

You will need to read the parts concerning:

(i) blocktables, blocktablerecords,

(ii) selection sets

(iii) transactions.

A solution to your task would be: first identify the line (perhaps use a filter on a selection set) then remove it from the "model space".

Ok found the answer.

This example creates a lightweight polyline, then erases it.

In the .net developer's guide: http://docs.autodesk.com/ACD/2010/ENU/AutoCAD%20.NET%20Developer's%20Guide/index.html?url=WS73099cc142f48755-5c83e7b1120018de8c0-22be.htm,topicNumber=d0e2452

enjoy!
