January 2017 - this course is brand new. Enrol now to be the first to benefit and to get the instructors full attention!

If you're an interior designer you need this course!

  • Organise with layers, styles and scenes so that you can easily switch between architectural drawings and 3D design views
  • Produce electrician drawings, plumbing drawings and section cuts at the click of a button - all within SketchUp
  • Render photorealistic images with reflective surfaces, lighting and custom textures using Twilight from within SketchUp
  • Receive a full PDF copy of my published workbook that compliments this course, available on Amazon/Kindle/Apple Books but FREE to all course members

Its likely that you've used and liked SketchUp - the once-Google software now owned and operated by Trimble that is free at entry level and easy to use. SketchUp makes it easy to build furniture, buildings and entire towns all from your imagination or replicating reality. Perhaps, like me, you started your Interior Design journey by obsessively building and designing room after room in SketchUp.

Now its time to either go back to SketchUp or improve your experience of it - by harnessing the powerful system that harnesses SketchUp's Layer organisation, styles and scenes. This system means that you can switch between a designing view and a 2D plan, a wireframe and a cross section, a view of the clients home with existing items in grey and proposed changes in green, a view that shows only the internal fixtures of your design or one that shows only the walls. 

Without this system it is likely that the only way you could do these things was to copy your model and modify it for specific uses - deleting what wasn't needed in each one. But any changes in one model would need to be copied into others. This is of course highly inefficient and ultimately unworkable - the system covered in this course will revolutionise your workflow to use just one model to cover everything. Make the change once then just switch views to see the technical plans, elevations and sections with the new change reflected.

Its not only the organisational system we're covering. We're also going to learn how to use Twilight Render. This is a SketchUp plugin, again free at entry level, that works directly from within SketchUp to render photorealistic images. We're finally going to be able to: 

  • display bumpy textures without modelling the bumps into the model
  • have reflective surfaces such as mirrors and shiny surfaces
  • have realistic 'scenery' seen outside windows without modelling
  • create light sources that brighten your room as per your own lighting design and set up

All this will help you to make SketchUp your main or only software to do your Interior Design work. You'll be able to produces work at a new speed and efficiency. Small changes now no longer mean hours of extra work tweaking all the architectural drawings. You are just one click away from a plumbers plan to an electricians plan, a cross section and an ideal view set up ready to render.

Have a look at the free preview videos to see the system in action and I can't wait to see you inside the course!

Who is the target audience?
  • Interior Designers who wish to use SketchUp and/or Twilight more efficiently
  • Designers from other fields looking to branch into the Interior Design Sector
  • Design Students who wish to make their portfolio quickly and with excellent quality
  • Interior Designers who wish to switch their software to the cheaper but powerful SketchUp Pro and Twilight Pro

Heres a quick lecture explaining why it benefits you to get involved in the course discussion area plus how to get in touch and find me in the SketchUp 3D Warehouse.

Udemy Features & Student Engagement

Heres what you should already know before taking this course - please note that this is NOT a beginner SketchUp course, it is for improvers, and for those with a particular niche (Interior Design) to fulfil.

A little bit about me so you know why I created this course and why I'm qualified to teach it.

About Me

Links and instructions to install SketchUp & Twilight - both SketchUp and Twilight provide FREE versions of their software, not for commercial use. The entirety of this course can be completed with the free software, but by the end of the course you should be confident in purchasing the pro versions in the knowledge that you can use the tools appropriately for your future designs.

Installing SketchUp & Twilight

Heres how to download the course worksheets. Printing these sheets will make the course A LOT easier as it helps you recreate the steps you've seen in the course videos, and make targeted reminder notes as you go.

These worksheets are THE SAME content as my published book so rest assured you're getting a tonne of quality information all with the ability to print at home.

Template Setup
5 Lectures 21:57

Setting up the SketchUp model to you preference of imperial or metric measurements, snapping to a particular length when moving objects and precision settings.

Preferences setup

The 1st stage of the workflow set up - setting up a whole host of layers that we'll be able to use to categorise every object in our model.

Setting up layers

The second stage of the workflow setup - setting up different style options for different ways to display the model - from a 'normal' view with textures showing to a specialist view to check the geometry of the model faces are aligned correctly (extremely important when it comes to rendering our model).

Setting up styles

The final stage of the workflow setup - bringing styles, layers, camera angles and specific sections cuts together into Scenes. This means that at the top of your screen you have quick 'tabs' that you can use to easily switch between all sorts of technical and useful views of your model.

Setting up scenes

Creating A Room
7 Lectures 19:56

Learn how to bring in an image of the measurements you take on site. This makes it quick and easy to replicate the model. I provide a sample drawing to work from - everyone on the course is designing the same example room. Check the resources section of this lecture to find the PNG file with the site measurements.

Bring in reference image

Here we build and categorise the walls that make our existing architecture. Its the first time we see how to use our layers and organisational system properly.

Build walls

After the walls are built we add the rest of the existing architecture - in this case door, windows, floor and ceiling. This completes the 'frame' of the space you are designing for your client.

Build the rest of the 'existing' architecture

The simplest step in creating our design is importing furnishings from the 3d warehouse. This lecture shows how to organise the groups and layers so that the model works with the system we're learning.

Adding and organising furniture from the 3d warehouse

Some objects need to be drawn differently in 2d and 3d - for example a door in 2d is drawn with an arc to denote the swing of the outer edge, whereas in 3d it would not make sense to show this arc. In this lecture we discover how to make these types of objects work correctly in both views!

The door - how to model objects that are different in 2d and 3d

Twilight Render
7 Lectures 21:24

Woo hoo! We're going to do a render! This first step covers how you install and use Twilight in its simplest form.

Our first render!

The quickest way to adjust the render is to tweak the environment settings. This controls what imagery is shown in the background, and it adjusts the overall ambient light that reaches your model.

Editing the 'environment' - sun, sky and background

We're creating a mirror in this lecture - one that will actually reflect what it should reflect! It will introduce the learner to the different materials we can apply to a surface using Twilights built-in choices.

Editing materials - add a reflective surface!

Real lighting! In your SketchUp model! It's easy to add Twilight light sources to your model, and edit their settings to match real-world lights by finding their physical size, K-colour value and Lumens strength.

Adding and editing real lights to your model

By organising the lighting in a certain way, we're going to be able to generate 2d electrician plans with just one click.

Organising the lights within the model

Some surfaces are noticeably textured - tiles, bricks, wood, even specific paint effects. Instead of needing to actually create these textures in your model, you can apply a bump image to the surface using Twilight. We learn how to do this by creating a clay/terracotta style wall which is smooth in the model, but rendered with distinct texture.

Adding 'bump' textures to surfaces

Rendering our Model
5 Lectures 08:21

Our renders are never going to be perfect first time - heres where we learn how to adjust settings here and there, and how to add objects so that our renders look really realistic - to the point where you wonder if its a photograph or a model.

Tweaking the model settings and adding realism

The simplest (and my most used) render setting is a non-progressive render. We learn what this means and what number to go for.

Non-Progressive Rendering

For truly stunning photo-realistic, portfolio-ready renders it is likely you'll need to choose a progressive render. This lecture explains how to use them (and why you might not want to).

Progressive Rendering

The printable workbook that comes with this course explains these advanced settings in detail, but we learn a little about these settings in this short lecture.

Advanced rendering options

Final Section
3 Lectures 06:06

It takes less than 5 minutes to explain how to generate 2d architectural drawings from plans, elevations, sections and detail, to specific plans needed for Electricians and Plumbers in your Interior Design Project. THATs how powerful this organisation system is - hours of work in just a few clicks.

Producing architectural drawings - plans and elevations

Wow the bulk of the course is finished! Well done! I'm covering very quickly why you might find loads of bonus lectures in the future and asking students to ask questions and show-off their new portfolio.

Designer & Entrepreneur

Kim Debling owns and runs her design company Kestrel Design from the comfort of her home office. Her employees and freelancers all work from home too as she and they value the freedom and lifestyle this affords. She began and built her company over several years whilst working full time as an Air Traffic Controller. She is focused, dedicated and frantically entrepreneurial. She also has a thirst for learning and passing on her knowledge that perfectly aligns with what Udemy offers.

As an Air Traffic Control Officer she was a supervisor, instructor and examiner - guiding new Air Traffic Controllers as they come into the job and then signing them off as suitable to control solo. It was a rewarding experience - especially seeing under-confident new controllers shine and become more qualified themselves. Her calm, no-nonsense instructional delivery was honed during these years in this fast-paced but safety critical training environment.

Due to the stressful nature of the job, Kim started to become extremely interested in self-management of stress, self-improvement and the work-life balance. Over the years she has become passionate about regaining control over our own lives and working out what works for each individual. This is often reflected in her courses, social media channels and products.

Kim's day-to-day involves building websites, creating digital products, books, designing packaging and generally stretching her left brain hemisphere. Her honours degree was in Internet Computer Science and she has kept up to date with many skills and built upon them.

Kim is married to Steve, a helicopter pilot, is mum to baby Rose, and has two cats - Nala and Duchess.
