Patterns using Blocks?? (Useful for AutoCAD LT users without Superhatch)

Hi,
In one of my previous posts I had mentioned about MINSERT command. This post will explain how to use a minsert block effectively for creating fill-patterns (like hatch) in AutoCAD. 
AutoCAD LT does not support Superhatch command. So, unless you are good at defining pattern files, I think, this method what I explain here is the best alternative one could think of.


Say, I have a special type of roof tile of 200mm x 300mm, which is like this;




Here is the roof where I want to fill the pattern of this tile;


Let us see how it is done.
Create the block of the Roof tile. (Here I created it by naming it as "Roof Tile") Keep the basepoint at the lower
Create polyline boundaries for the four slopping sides of the roof.
Use MINSERT command and create a minsert block. (Don't know? Please see my previous post).
Here is my command window for your reference;


The minser block now should look like this;


Use the XClip command to clip the minsert block. For this, type XC and press Enter key. Pick the minsert block, rightclick and choose the option "New Boundary" and again choose the option "Select Polyline", now pick the polyline boundary for the slopping side. Done...

Now copy the same minsert block and rotate it by 90 degree and place it over the next slopping side of the roof. Use the polyline to clip the block. Now take copies of the block and rotate then and do the clipping for the other two sides too.






Wait for more... Have a nice day friends…!!
