I recently tried to re-create Willy Wonka'due south Everlasting Gobstopper, and let me tell you that simple looking trivial piece of candy was non then uncomplicated to model. No wonder Mr. Slugworth was trying to steal the hole-and-corner! I tried budgeted information technology with several different techniques and, in the end, the results I desired required 3D sketches. I would similar to hand you the SOLIDWORKS gilt ticket to the secrets I learned and discoveries I made while working with 3D sketches to model this fictional candy.

Creating Geometry

In a 3D sketch, new geometry can be created in 3 dimensions past referencing bodies, planes, surfaces, or vertices which already be. This tin be equally elementary as converting edges or clicking on vertices for starting and ending points of the geometry. In my Everlasting Gobstopper model, I used the edges of a solid body to create construction geometry in 3 dimensions. I then used the midpoint of this construction geometry to sketch the centerline geometry for a loft to make the candy branches.  I found creating the centerline free mitt, without anything to reference, the nearly challenging part near using a 3D sketch.

When creating free hand geometry in a 3D sketch, I think the most of import affair to understand is that sketch geometry is inherently second. This means that even though three dimensions are potentially available, it will default to simply using two when geometry is outset created. After information technology is created, the geometry is then able to be dragged and positioned in three dimensions. I used my cursor feedback to take advantage of this.

When I created my 3D sketches for the candy branches, I paid particular attention to my cursor and space handles. The cursor identified the axes labels comprising the plane I was currently working on. The space handles displayed arrows mimicking the global coordinate arrangement where I final clicked and highlighted in red the two axes creating the plane I as currently working on. If I needed to switch orientations, I used the tab primal to rotate through the three plane options. These two items helped me to orientate the geometry when I was initially placing it in my sketch. Once placed, I repositioned the end of the geometry to make the branches look more than organic.

Some other available selection to help y'all take advantage of the default two dimensional inclination of sketch geometry in a 3D sketch is a 3D sketch plane. A 3D sketch plane is a 2D aeroplane that only exists inside the 3D sketch. When activated, sketching will happen exclusively on that plane and y'all will get behavior like to when working in a second sketch. To add a 3D sketch plane become to Tools>Sketch Entities>Plane. To utilise an existing aeroplane in a 3D sketch, select the plane and become to Insert> 3D Sketch On Plane or double click on the plane. I didn't utilise this technique in my model, but I thought it was worth mentioning.

Relationships

Automatic relationships are still indicated through the xanthous flags adjacent to your cursor in a 3D sketch. However, in a 3D sketch you volition find there are fewer instances and types of relationships that tin be added automatically. In my Everlasting Gobstopper 3D sketches, my employ of an existing torso and construction geometry did not require me to add any additional relationships. Withal, I establish information technology helpful to review all the different types and necessary selections for relationships in a 3D sketch considering they are unlike.

All the existing relationships that y'all can have in a 2nd sketch are still available. Still, some of these relationships volition have additional options or requirements in a 3D sketch.

There are too additional relationships that but become available to you lot in a 3D sketch.

Dimensioning

Once I had the centerline for my Everlasting Gobstopper processed branch in the correct position, my last footstep was to add dimensions, which would fully define the sketch. Fully defining a sketch is an import best exercise that should ever be followed, specially in 3D sketches.

When calculation dimensions in a 3D sketch, by default you will start out with the absolute value. If you lot would similar the dimensions to only be along ane management, yous can use the tab fundamental to switch to but forth ten, forth y, or forth z. By continuing to striking tab will cycle you dorsum through the options starting at absolute once more. The cursor will update to tell you which direction the dimension is along.

Working with a 3D Sketch can be challenging, however, it is a useful tool. Similar my Everlasting Gobstopper, there may exist times when a 3D sketch will be necessary and I hope now you volition be more comfortable working in this sketch state with SOLIDWORKS. If you don't believe me, just mind to the Oompa Loompas!

Oompa loompa doompety doo
I've got a model claiming for you
Oompa loompa doompety dee
If you are wise you'll listen to me

What do you get when you effort something new
Modeling as much as yous engineers do
Why 3D sketches are not so hard now
Not when CADimensions showed you how
You volition actually like the wait of information technology

Oompa loompa doompety da
If you 3D Sketch then yous will go far
You lot volition model in happiness also
Like the oompa loompa dompety doo!

Happy Modeling!
