Click once on the Sketching tab,
Once the P appears then click once on the mouse. Next, move the mouse over to the right so it lies somewhere on the positive x axis; Prior, to clicking again make sure that a C appears.
You should now have a line that starts at the origin and terminates somewhere on the positive axis.
At this point, the dimension of the line needs to be specified, so click once on the Dimensions tab, . Then, click once on the Horizontal button, . The next step is to click somewhere on the y axis and then click on the endpoint of the line (the point that lies upon the positive x axis). Now, raise the cursor (which should now be a horizontal line and a pencil) above the line and click once; You should see a dimension labeled H2 above the horizontal line as shown below.
Now, the length of the line will be manually edited. Underneath the "Sketching Toolboxes" there will be a column called "Details View". In "Details View there is a subcategory called "Dimensions: 1". Change the numerical value of H2 to 4 meters and press enter.
Line Body
The next step is to turn the line that was drawn into a line body. In order to do this click on Concept which will be on top of the Design Modeler window, then click on Lines from Sketches, as can be seen in the following picture.
Next, click on the blue horizontal line that you drew. The blue horizontal line should have changed from blue to yellow as can be seen below.
In the "Details View" column a yellow box to the right of "Base Objects" should be highlighted in yellow. Click on the yellow box and then click apply. Then, click on the "Generate" button which has a lightening bolt on it and is located on the top left portion of the Design Modeler.
