Blender 2.8 parametric modeling: Drivers, Custom Properties, and Shape Keys for 3D modeling

The use of parametric controls for 3D modeling in any software can transform your workflow and give you the flexibility to quickly change the shape of any 3D Object. In Blender, you won't find parametric controls as a default option, but using the right tools, it is possible to add those parametric options.

If you use Drivers, Shape Keys, Hooks, and Custom Properties, you will be able to create parametric controls that will help in architectural modeling projects and also animations. You will be able to add properties to objects that works based on a context.

Do you want to learn how to add parametric controls to objects in Blender 2.8? With the Blender 2.8 parametric modeling book, you will learn all the steps necessary to create such controls. The book covers all necessary aspects of the process, which will also involve some basic math to create expressions to control objects.[/vc_column_text][vc_row_inner][vc_column_inner][/vc_column_inner][/vc_row_inner][/vc_column][vc_column width=”1/2″][vc_row_inner][vc_column_inner width=”1/2″][vc_btn title=”Order paperback” color=”danger” align=”left” i_icon_fontawesome=”fa fa-shopping-cart” add_icon=”true” link=”url:https%3A%2F%2Fgeni.us%2F4CEL2N|||rel:nofollow”][vc_column_text]Paperback ships from:

Blender 2.8 and parametric controls

What will you learn with Blender 2.8 parametric modeling? The book has a practical approach to Blender 2.81 tools and features, using examples and guides to describe how you can perform the most important tasks related to parametric modeling.

Here is a list of all the chapters:

Chapter 1 – Preparing for parametric modeling
Chapter 2 – Drivers for connecting properties
Chapter 3 – Custom properties and Drivers
Chapter 4 – Shape keys and Hooks
Chapter 5 – Parametric walls
Chapter 6 – Parametric furniture models
Chapter 7 – Parametric stairs
Chapter 8 – Creating a parametric model asset library

Preparing for parametric modeling

In this chapter, you will learn the requirements about parametric modeling with Blender and some of the main differences between parametric modeling and BIM. Here is a list of what you will learn:

What is parametric modeling?
Differences between parametrical modeling and BIM
Rules to create parametrical modeling
Units set up for modeling
Using imperial units
Precision modeling with Blender
Controlling scales for modeling
Adjusting the origin point of 3D models

Drivers for connecting properties

The next step to get our models with parametric controls is to use Drivers in Blender to link all types of properties. In this section you find information about:

What are Drivers?
How to add Drivers to properties
Managing and reusing Drivers
Duplicating existing Drivers
Controlling properties of an object with Drivers
Adjusting origin points for Drivers

Custom properties and Drivers

You will learn how to add and set up those Custom Properties to create a custom control panel for any group of objects. You will work with expressions and also learn about operations that can help you make visibility controls:

What are Custom Properties
Adding and editing Custom Properties
Changing the precision and values for Custom Properties
Controlling multiple objects with properties
Using controls like switches
Apply a ternary operator for expressions

Shape keys and Hooks

In this chapter, you will learn how to add and manage Shape Keys to create parametric controls for 3D models. Besides Shape Keys, we will also learn how to work with Hooks to deform vertices of a polygon based on helper objects.:

How to work with Shape Keys
Adding and creating Shape Keys
Using Shape Keys for modeling
Options to manage Shape Keys
Connecting Shape Keys with Custom Properties
Using ternary operators with Drivers in Shape Keys
Apply Hooks for 3D model control

Furniture and external assets

What would be of an architectural visualization project without furniture models and assets? Do you want to learn how to handle and manage those assets in Blender? You will learn in this section:

How to import assets to Blender
Use the Append and Link options
Working with linked external libraries
Editing external libraries assets with furniture
Optimizing and fixing furniture models
Prepare furniture models for reuse in Blender

Parametric walls

The objective of this chapter is to demonstrate how you can create a wall model and add a couple of parametric controls:

Controls we can add to a wall model
How to quickly model walls for parametric models
Using extrudes and the context menu
Reviewing edge lengths of objects
Adding a height control to walls
Working with width controls for windows and doors
Create expressions for width control

Parametric furniture models

The use of parametric controls for furniture models will open a wide range of options for customization and settings for architecture. In this chapter, you will learn how to create such controls for a chair:

Planning controls for a chair
Organizing the model with hierarchies
Add visibility controls
Control the seat height and width
Adjust the backrest to follow all seat transformations
Control the backrest height

Parametric stairs

Our objective now is to create a parametric staircase that will demand more complex expressions and object setup. You will learn some new options regarding object setup, like the use of constraints to create hierarchies and also set the Empty controlling a Hook in a particular location. Here is what you will learn:

What controls makes a parametric staircase
Parenting with constraints
Preparing the model to receive Custom Properties
Creating a Step count control
Changing step width and height
Control a handrail model
Work with expressions and equations to adapt the handrail
