What is the start Point coordinates for each Line regarding to 0,0? ( We call that A for X and B for Y ).

What is the Angle for Lines? ( We call that Angle ).

How many line you need to create that base shapes shape?.

Honestly, this is very important for you if this is first time you are making *.pat file and if you are making complex hatch pattern.īecause you can understand what is happening in pattern, for example for each pattern you need to have information about separate item like below list: Ok, let’s talk about first item ( Tile 300×300 Grout 10 )Īt first i should tell you one important point, if you need to define any new hatch, my offer is try to draw that hatch with line in AutoCAD regarding to simple X,Y axis like to the below picture. I want to explain this with three different type of Hatch with three separate post in my blog, all dimensions are mm. Now i want to make it documentary and share this with you my friend, then every time i forgot something i can make review this post for myself.Īs you maybe know we can try to create *.pat file with notepad in our computer and after we wrote our codes we can save our files with.

With many try i understood more about *.pat file, but every time i didn’t try for create more than 1 or 2 years i forgot something.

I think that was around 12 years ago, i bought one book and i read one interesting thing about how we can understand what is happening in AutoCAD.pat file and how we can make decode that.įor that year, regarding to my experience and knowledge and also regarding to the explanation of that book, that was very hard for me to understand what is happening in *.pat file, but that was first start. I know this is not unique post but i’m sure this could be one of the useful post for all Revit or AutoCAD users,
