: Why I am getting this extra part of lines and how to resolve it? Here i am getting extra line that i dont want.I tried scaling down the size of line but it did not help.So can you please

Why

Well, take two lines that meet at a point.
When you make them bigger, you're basically drawing two parallel lines around the baseline and filling whatever is between those lines with your stroke fill color.
So, the more acute the angle between your (base)lines, the farther the external parallels will meet, causing these spikes.

How

The Stroke panel has several corner options. Someone else already suggested that you go for a Round or Bevel join, but even if you select the regular join the Limit field will let you tell Illustrator how far this point can go before being automatically trimmed. Insert a value near to the line width and experiment a little.

You can change the stroke endpoint. If you do not have your stroke panel open you can go to Window - Stroke.

Select your path with the direct select tool. Go to the panel options and under Corner, select Round Join or Bevel Join



If you are worried about lines protruding, you can also create an outside shape and use that as a clipping mask.
