In the last post in this Cabinet Configurator Tutorial, we added a new work plane, created the Plan sketch, then created the geometry that represents the plan version of the face frame. In this sketch, all geometry from front to back that is constrained to the projected points –such as the face frame, will not need dimensioning. The projected points will smoothly update to any changes in the parameters that dive the geometry they were projected from. Any geometry drawn front to back however, will require dimensioning.
We left off the sketch with the face frame constrained to the points that were projected from the elevation representation of same –which automatically gives it it’s thickness dimension. Looking at the Status Bar, you can see there is one dimension needed, which is the width. If you click and drag either of the ends of the sketch, you can drag it to a new width. Create a new parameter named Overall_Width, and give it a value of 36”. Dimension the front-most line with the new parameter, and you will have a fully constrained sketch…
In the last installment of this Automated Cabinetry Inventor Tutorial, we got all the way around the cabinet with our sketch, but there are still a few things to add. We need to get the applied toe kick in place, add a locator for the adjustable leg, and add the rail representations in the top nailer frame. If time allows, we will start on the variable sketches that will begin to describe the variation available to the base design.
Before we start sketching, we need five more parameters (to start) to define the kick and its location, and to define the rail width for the top nailer frame. Open the Parameter Editor, and if yours looks like the one below..
In the last installment of this Inventor Tutorial for automated Cabinet Design, we damn near finished working our way around the side elevation sketch, but still have the bottom to go. From there, we need to define the rails for this, the main version of the face frame.
The sketching begins with two parallel lines that are each coincident to the line that represents the back of the face frame and the line that represents the inner face of the back panel. Remember that every line in these cabinets either needs a horizontal or vertical constraint with a few exceptions that will be called out, so from this time forward, it’s up to you to not screw up.
In the last installment of this Cabinetmaking Inventor Tutorial, we created a couple parameters, sketched in the face frame profile, and dimensioned the new face frame using the new parameters. Today we will continue sketching. The features we will need to portray in this elevation slice are a top nailer frame, a back nailer, the back, the deck, the kick, and the face frame’s rails.
This unit will be designed to rest on a cleat on the wall in the back, and have adjustable feet in the front. The kick will be attached to the front legs with clips. I’ve never built one like this, but someone once described their shops build method as being very similar to this, and I thought it was a pretty elegant way to build a good cabinet without going broke –as so many cabinetmakers do every year.
Since we’re working our way around the cabinet in a clock-wise direction, we’ll get started today with the top nailer frame. The top nailer frame butts into the back nailer –which butts up against the back, so hopefully we can get to all of them. We’ll start by drawing a set of lines in exactly the same manor as in the last post in this Inventor Tutorial series…
In the first Inventor Tutorial in this series we went through a lot of the Inventor basics, and left off with a Layout Part with a couple parameters in it controlling a rectangle that describes the extents of our model straight down the middle. In this post we will start to refine the sketch to start representing the features of our cabinet.
We will begin sketching at the Centerpoint, and work our way around the model clockwise. We will add parameters via the Parameter Editor and apply them to the sketch as needed. I am hoping to make this cabinet configure to have, at a minimum, a bank of drawers and a door/pair of doors. We could –and may –go a lot further, but for starts, let’s leave it at that. Open up the Automated Cabinet Design.ipt, and get to the RIGHT view according to the View Cube…
In this, the first Inventor Tutorial in the Automated Cabinetry Configurator Blogtorial Series, we will begin with the creation of the Layout Part’s elevation sketch –but before we do that, I should briefly explain how our model will relate to the 3D space we will be modeling in.
Inventor uses a Right Handed Cartesian coordinate system, whereby your base plane is XY with the Y axis pointing up towards the top of your monitor, the X axis pointing to the right, and the Z axis pointing out of the computer monitor towards you. The model would come out the same no matter which coordinate system is used, but we need to stay on the same page if you want to end up with a working model at the end of this blogtorial.
In the video below I will go through the steps of starting the first sketch in the Layout Part. This part will control the size and location of everything in this model…
