Introductory Tutorial #06: Extrude, Array & Twist

Extrude is a common function in all 3D design applications.  But, like other commonly available features found generally in all 3D package and Moment of Inspiration, MOI seems to go beyond the norm by proving additional, not so common, capabilities.

EXTRUDE

Extrude allows us to pull a 3D object from a 2D shape.  In its simplest form, it allows us to give depth to a 2D shape by extending that shape upwards for downwards.  A circle, for instance, can be EXTRUDED to become a cylinder.  A square can be EXTRUDED to become a box.

EXTRUDE - TO POINT

Moment of Inspiration allows us to extrude a shape in ever smaller increments until the shape comes to a point. Instead of a circle being extruded to a cylinder it can be extruded to form a cone.  By default, EXTRUDE TO POINT operates at 90 degrees from the plane of the object being extruded.  But, by selecting UNLOCK, the point can be placed anywhere in space.

EXTRUDE - SET DIRection

Rather than being restricted to 90 degree extrusions, Moment of Inspiration allows us to select a straight direction in which the extrusion will travel.   Combined with ARRAY, this can be used to create some very interesting and complex shapes.

EXTRUDE - SET PATH

While EXTRUDE - SET DIR is restricted to a straight line, EXTRUDE - SET PATH permits us to draw a path which will be used to direct the extrusion's travel.  This allows us to extrude more organic kinds of objects.

EXTRUDE - TAPER

This is a new capability in Moment of Inspiration.  Currently, it is only available to owners of Moment of Inspiration that download the MOI 3.0 Beta.    It permits the user to select an extrusion angle and distance.  It's great for creating bases and expanding shapes.

Here is a tutorial that covers each of these EXTRUDE capabilities.

Introductory Tutorial #05: Revolve & Rail Revolve

One of the joys in using Moment of Inspiration is that it seems to go beyond mere functionality when it comes to features standard to most 3D design packages. 

REVOLVE is common to every 3D package I have ever explored.  In every package, we get the ability to create a profile and then revolve that profile around an axis to create a 3D object.  Moment of Inspiration has that feature without some of the confinements in other packages.  But, it goes well beyond simply revolving circularly around a simple axis. by allowing us to select a RAIL to guide how that revolve is to be performed.  This allows for more interesting and complex revolve results.

It is this kind of versatility that makes Moment of Inspiration a real joy to use.

Introductory Tutorials #4a & 4b: Boolean Functions

Boolean Functions are extremely powerful in Moment of Inspiration.  In fact, it was probably this aspect of design that first sold me on Moment of Inspiration above other 3D design products. 

I try to keep my tutorials under or around 10 minute in length.  So, even at the introductory level it took two sessions to even begin to explore the richness of Boolean functions available to designers.  These functions fall into four categories: Difference, Union, Intersection and Merge.  And, each of these functions work on both 2D and 3D features.  And, they all require at least 2 different objects to be selected.

BOOLEAN DIFFERENCE

Boolean Difference requires the selection of two or more different objects in two different categories. It subtracts material from a "Base Object(s)" based on the characteristics of the "Subtraction Object(s)".  It is typically used to cut holes or remove portions of an object using a complex shape. 

BOOLEAN UNION

Boolean Union also requires the selection of at least two different objects.  They must be touching.  That is because they are combined into a single object. 

BOOLEAN INTERSECTION (ISECT)

Boolean ISECT or INTERSECTION is a very interesting function.  It creates a NEW object by doing something that can best be described as a reverse difference.  The parts of those selected objects that do NOT intersect with each other are removed.  And, a new object is created that encompasses only the area in which both original objects intersected.

BOOLEAN MERGE

Now it REALLY gets crazy.  This command KEEPS the parts of the selected objects that did not intersect.  Generally, the result is a new object for each of the selected objects.  But, then it also creates an intersection object!  For two original objects, this generally results in 3 new objects being created.

Here is the first of our explorations into Moment of Inspiration's Boolean functionality.  In this case, we cover just UNION and DIFFERENCE to create a housing for something like an automobile thermostat.

All of the BOOLEAN Functions are explored in this second half of this tutorial.

Seeing the functions at work is worth a thousand words!

Introductory Tutorial #3: Cookie Cutter from Circles

Our third introductory tutorial for Moment of Inspiration (MOI) explores how simple circles can be used to create an animal shaped Cookie Cutter.  MOI's command set makes this task a breeze!

Video Response to a User's Question

One of the great things about having the internet and YouTube is that it gives us the ability to answer tough questions very quickly and easily.

A MOI user posted a comment in response to my 2nd tutorial asking a specific question regarding how to do something.  Fortunately for them, it happened that I actually knew that answer!  It could just as easily gone the other way resulting in TWO of us being completely baffled.  LOL!

They wanted to split a single cylinder into two branches like a "Y".  So, here is at least one way to accomplish that task.

I post it here so that others might also benefit.

While it seems simple enough in this video, when we are first faced with learning any 3D application, ALL of us are overwhelmed by completely unfamiliar concepts and tools.  I had NO idea what SWEEP or LOFT were supposed to be able to do when I first started learning Moment of Inspiration. 

So, don't be discouraged.  It will all make sense before long.  :)

MOI Introduction #2: Naming Objects

It may seem odd to immediately jump into a tutorial about the importance of naming objects in Moment of Inspiration so early in the learning curve.  But, there are good reasons for doing so,

Because the basic design strategy is to use 2D drawings to create 3D objects,,, and, these 3D objects often obscure these original 2D drawings, we need a way to access them even when they are obscured.

But, the power of naming goes well beyond that.  It provides a way for us to completely control what objects are ultimately sent to the STL file for printing and which are not.  Very often, we might want to select a single object in a group of objects for printing.  There is no way to do this, beyond completely deleting objects from the design, unless they are named.

So, it's a good idea to understand the importance of naming objects very early in the learning curve to make it second nature as we design,

While it is not the primary focus of this video, we also cover more interface customization capabilities and some 2D to 3D operations like EXTRUDE and REVOLVE as well as the SELECT ALL command.

MOI Intro #01: Setting Preferences

When I first began using Moment of Inspiration, I searched for tutorials suitable for helping me get started.  And, believe me, I needed VERY basic tutorials!

What I found, beyond the three tutorials on the Moment of Inspiration web site, were a lot of videos showing incredibly cool things that can be created with MOI.  And, I also found any number of tutorials without the benefit of supporting narration.  I don't do well trying to follow mouse selections when learning a new product.  I need someone to talk to me.  :)

So, now that I have been using MOI for awhile, I thought I would create the kinds of tutorials that I had been hoping to find.   Simple and narrated.

The first tutorial, in a new series of introductory videos covering the basics of Moment of Inspiration, is now on YouTube.

Setting up our working environment to best suit our preferences is very important to getting the most out of Moment of Inspiration.  Customizing the grid and the Axis lines is covered.

Using the Split Views and Full Views is also described.

I look forward to hearing from you for feedback to help me deliver the kind of help you would like to see.  You can comment here or on YouTube.  Together, I think we can move much more quickly into doing incredible things with Moment of Inspiration.

Welcome to the Moment of Inspiration User Blog

Moment of Inspiration (MOI) is a unique 3D design application.  It combines some of the precision capabilities of a Computer Aided Design (CAD) program with some of the more free flowing design capabilities of the more organic 3D design applications.  And, it packages all this power in an interface that I have found to be relatively easy compared to other 3D packages.

While I am by no means an expert in MOI, I have come to really appreciate it.  This blog is dedicated to helping people explore Moment of Inspiration during the free trial period and quickly get up to speed should they select it as their 3D design application of choice.  Hopefully, all of us with get better, together, as we explore all that MOI can do for us.

My principle use of MOI is to create items to print on either a RapMan 3.2 or Cube 3D printer.  So, the tutorials will primarily reflect that purpose.

In the near future, I plan to create some tutorials specifically related to learning Moment of Inspiration.

But, in the process of exploring 3D printing, I created some videos that incorporated MOI as the design platform.  So, we'll get started with this blog by posting those.

VASE - FIRE 

While this is technically NOT a tutorial, it does demonstrate an object that was created using MOI (beta 3.0) and printed on a 3D printer.  The great news is that MOI is so powerful that this was done in a very short design session using the "Twist" function.

CUBE CARTRIDGE HOLDER

The Cube 3D Printer uses a cartridge based filament feed system.  This video demonstrates creating three different versions of a 3D printed rack to hold spare Cube cartridges.  Once again, MOI's power to be both precise and easy to use made this task a real joy.

3D TEST DESIGN

This video demonstrates creating an STL file that is designed to test a 3D printer's accuracy.  It's important that we print test objects with a new 3D printer to see how each individual printer might interpret and print a particular dimension.  If we want a specific inner or outer size, we may need to design smaller or larger than the required dimension.  MOI's accuracy is very helpful in this regard.

These are just just a few samples of the kinds of things that can be created in Moment of Inspiration.  In the near future, we hope to create some tutorials specifically designed to introduce this wonderful program to new users and potential users.

NOTE:  I have no official link to Moment of Inspiration.  I am simply a user that appreciates what this 3D application can do for me.
