Designing a sofa in your 3D Model through SketchUp

by global

In this article we are going to discuss how SketchUp enables us to furnish our Interiors through live furniture modelling. Furniture is a broad topic; it can be couches tables sofas cushions, beds, cabinets, Roll Top desks etc. Furniture is one of the essential requirements of every home it makes your life simpler and gives you comfort in the house. Comfort is vital for our rest, furniture not only enhances the looks of any home or office but, it also offers the best comfort for rest and relax.

The importance of furniture is felt by everyone. One of the things that complete one’s house is furniture. These live load elements become a necessity and rather the most crucial part of designing an interior space. The evolution of furniture from their basic utility to them being a luxury symbol and their beautiful designs are taking a leap in today’s world. Furniture brings about changes in the space and its functionality. The range, variety of designs and type of furniture are making every dead and dull area a lively experience.

To incorporate the furniture, say here a sofa in the 3d model, start the base on the ground, by drawing the rectangular components of Sofa in 3 pieces. Create an arc on the corner of the component, use a standard arc to create a perfect arc, now in the middle sections grab the points and do the arc.

Creating Structure of the Sofa 

Double click on both the ends to make it a component and save the diagram, just rotate 90 degrees and select an average looking sofa, make the bottom section 9.5 inches. Now the next way is to triple click to separate the component, make the cushions and arms separately to add details to your work. Draw a reference line and draw a rectangle, just extend the base to 5’ and 28” to model the back of the sofa. Double click and make it a component by saving it at the back of the couch.

Creating the Arm of the Sofa 

Click and make the arm by pulling 4 inches and pull it through and make a new component and save it by naming “The Arm”.

Rotate Keys 

When you move you get the rotate keys, scale the components and lengthen the sofa. 

The next step is to offset the arc of the sofa by double click and right clicking it, then save the file and name it as back of the middle in front portion and make it a component and save the component by naming it “Bottom of the middle”.

Now the initial pieces of the sofa are crafted, and it it’s time to take the basic decision, about how much we want the arm hold, back of the chair and other pieces separately or as one piece.

Add Minute details to the Sofa 

The next important procedure is to explode the sofa in per piece, so that the minute detailing can be done. Add on the cushions on the sofa by putting 4.75 inches, make it as a whole component by saving as side cushion1.

Add Cushions 

Repeat the steps by adding the cushions on the sofa make it as a whole component by saving as side cushion2.Explode the arc and, triple click it on one component, grab the surface by clicking Control + C. Push Pull to the cushion height and save it as component Cushion Middle.

Customise the default tool bar, the best function in Sketchup is one customise the design of the furniture’s. Now add in the cushions, make a 4-inch cushion and pull it up press it 2 inches into the back of the crowd. Triple click and make it a component and save it as side back cushion 1. Next step is to Push/Pull and extend the cushion triple click and make the component side back cushion 2. It’s time to soften the edges of the cushions.


FredoCorner performs the rounding of the edges and corners of 3D shapes along a 2D profile, in 4 modes: Round, Bevel, Subdivision Mesh and Chop Corner. FredoCorner also includes a Repair tool to undo any generated shape rounding.

Go to the tool pallets and then go to FredoCorner. The use of FredoCorner is to take the geometry and helps in rounding the corner. Fredo corner acts as a follow me tool. Now take the second cushion and soften every single edge by using FredoCorner.

 Adding Texture to the Sofa 

SketchUp has a unique specification, if you want to add on texture to your furniture you can do that by selecting the texture button.

Creating Legs for the Sofa 

Draw the legs of the sofa 3X3 inch square and add on the geometry, make it component and save it as a foot. Copy it on four sides of the couch, and then add four more legs on the arc of the sofa. Copy the foot and add on the extension of the sofa, so now the sofa has got its legs. Basically, sofas with legs allow people the advantage to stoop down less, making the act of sitting less strenuous, especially for individuals with leg, hip, or back injuries, or for the elderly.

Adding Materials on the Sofa 

In SketchUp we can Revamp the furniture by changing the colour of the fabric texture of the cushions and also one can add cup holder to the arm of the sofa.

SketchUp’s work area is a window into a three-dimensional world where one can build just about anything. It can be as big as the Empire State building or as small as an iPod. By using SketchUp just design the house inside and out, and build all the furniture for each room.
