Civil 3D – Part Builder Part 4

We will pick up where we left off from Part Builder Part 3.

Open our saved part “Wingwall sloped” from the last session.  Adjust the view so that you have something similar to the following image:

It’s time to speed things up a bit, so as I refer to procedures, I will once again detail them, and thereafter I will just state that it needs to be completed. 

Note: Halfway through I realized some changes needed to be made, in order for this process not to be more confusing than it might already appear.  If I missed any odd things in the images, or got out of sync with the variable names, please notify me, and I’ll do my best to correct them.

In this session we will create another offset plane, and additional profiles and transitions. Before we do, it would be prudent to create the remaining profiles that will be referenced to our (current) Right Plane. These will be the locations that the extending walls project into, the “tie in” points.  You should be fairly familiar with the basic procedures, Lord knows you’ve had tons of time to practice since my last post, we will pick up the speed a bit.

Civil 3D – Part Builder Part 3

We will pick up where we left off from Part Builder Part 2.

Open our saved part “Wingwall sloped” from the last session.  The image below should be representative of what we had before.

Model Parameters

The Model Parameters are the nuts and bolts variables that control the size of the part. The parameters are either dimensions or offsets that are controlling the size and angle of features, or parameters that the user has defined. Expand the collection heading, and you should be able to see all the parameters stored in the part, as well as the values currently assigned.  Lets create some user defined parameters to help us in our equations.

Right click on the Model Parameters collection, and select ‘Edit…’

The Model Parameters dialog will appear, allowing changes, additions, and deletions to the existing parameters.  On the right you will see buttons, all of which are self explanatory, with the exception of the ‘Calculator…’ button.  This allows you to pull variables form a list (without having to remember and type them), and evaluate the result of a proposed equation.  Any time you need to map a parameter to another, you can use this feature instead of typing if you wish.
