# Split line,Offset surface and Thicken in SOLIDWORKS

Split line,Offset surface and Thicken in SOLIDWORKS.

1. ### Step 1:

In this tutorial I am going to show you 3 tools,Split line,Offset surface and Thicken.

We are going to start with split line.

First thing we need to do is to create a sketch which we are gonna use for splitting this surface.I am gonna start a sketch on Front plane so I can see my surface from the top.

2. ### Step 2:

Here is the sketch,I just used offset sketch tool to create it,but it can be different shape.

Things you need to be careful when you are working with split line are that if the sketch is fully inside your surface zone it needs to be closed,otherwise split wont work.I am going to show you some examples now.

This is not a closed sketch,it is just a line ,but this would work too because it gets trough entire surface.

This would not work and an error would occur because the line stops on the surface,splitting surfaces or faces or solid bodies cannot be done like this.

3. ### Step 3:

When we cleared that off we are gonna actually start the command so you can see clearly how this works,you can find it under Curves.

Select Projection,in the red box select the sketch and in the blue box we need to select the surface of the face which we want to split.

This will just split the face or surface,not bodies.

Here you can see what we have done.

4. ### Step 4:

Now we are going to use our second tool,Offset surface.

We will use it to to offset this part of the surface.You just need to select the surface,I am going to offset it for 10 mm,with the arrows you change the direction.

5. ### Step 5:

Here it is,it keeps the shape of the part where we used offset,it just becomes smaller.

6. ### Step 6:

Now lets add Thicken to these surfaces,you can find this tool on Surfaces toolbar.

We need to select the surfaces we want to thicken,this will ad actual thickness to them because surfaces do not have thickness.I selected the top surface which was formed after offset,I am going to type 10 mm because and select the direction because I want it to go back to the first surface.

We cannot do both in the same command so we are gonna do the same for the other surface.We have also got that Merge Result option,if you uncheck it it will form 2 bodies.

Here it is,I hope that you learned something from this tutorial :)
