Hello, my name is Thom Tremblay from Concepts and Design.
00:05
In this course, we'll be taking a look at how you can reuse raster data to create 3D models.
00:13
The learning path will take us through importing raster data into AutoCAD,
00:17
processing the raster data to create vector data, bringing that data into a 3D environment,
00:24
and refining the sketch geometry created from it, and then building a 3D model.
00:32
In this video, we'll focus on opening the AutoCAD file using Autodesk Inventor to import the raster and vector data into a sketch.
00:41
We'll constrain the sketch geometry that's been imported, and then create 3D features from those sketches.
00:50
Autodesk Inventor has the ability to open or import data directly from an AutoCAD DWG file.
00:58
After selecting the DWG, use the Options button to access the File Open Options, and select "Import".
01:07
The DWG/DXF File Wizard will appear and will continue on to the next step.
01:13
In this step, you see a preview of the geometry and if you wanted to, you could select just the vector geometry using a window.
01:22
But to use the raster as a reference, we'll keep the Selection set to "All".
01:28
On the next tab, we can select how we want to treat the 2D data, as it's imported, and what we want to do with it.
01:36
We want to make sure that we create a New Part that is Projecting the wires to a 2D sketch,
01:43
so you will need to have the Wires selected in the 3D data options on the left.
01:48
Inventor detected that the model was drawn in inches.
01:51
We'll keep that, and we'll make sure that the template is set to a standard inch ipt file.
01:57
When we click "Finish", Inventor will bring in the sketch geometry as a new sketch.
02:04
You can see the raster data remains black, and the vector data is set to whatever the sketch geometry is, based on your appearance options.
02:14
I can get rid of the default Sketch1 that was part of the template and focus on sketch 0.
02:22
Because it's an Inventor sketch, you can immediately begin dragging components of the sketch and see the results,
02:30
creating constraints or displacing the geometry.
02:34
You can also add additional sketch constraints.
02:39
To speed up the process, we can use the Auto Dimension tool, deselecting the Dimensions, but keeping the auto Constraints.
02:47
The sketch will still require 32 dimensions to be fully constrained.
02:52
When we click "Done", it will add constraints to the sketch.
02:56
We can then begin to refine the rest of the sketch by doing typical pull and drag operations.
03:05
We can also use tools, like Extend or Trim, to build connections in the sketch.
03:13
Turning on the Constraint visibility, we can get a better feel for what needs to be done.
03:21
We can collinearity between the two sketches.
03:30
The circle in the sketch was brought forward to remind us that we need a hole there, so we can convert that construction geometry.
03:39
Now let's add a few dimensions.
03:42
The first dimension we'll add will be the overall length,
03:46
which is still close to the 6 inches we had scaled it to in the raster image in AutoCAD.
03:51
But placing that first dimension and changing its value will scale all of the vector elements in the sketch.
03:58
We'll add the other dimensions to the sketch, based on the raster image that was brought forward.
04:07
Now let's project the center point of the origin into the sketch,
04:12
so that we can drag the sketch down to that point, automatically constraining it,
04:18
and have it located based on the planes of the part.
04:23
Adding the last couple of dimensions and relocating things, now let's begin making 3D.
04:31
We really only need to use the sketch on the left.
04:34
But having the dimensions on the sketch on the right, based on the raster information, will help speed things along.
04:42
First, let's extrude the large rectangle, selecting the 3-inch dimension in the sketch on the right as the value.
04:51
We'll apply this and begin extruding the U-shape using the dimension in the search for that as well.
04:58
And we'll click "Ok" to hop out of the Extrude tool.
05:02
Looking at the feature that we'll need to create at the bottom, we'll use a different technique.
05:08
We could relocate the sketch or copy it.
05:11
But instead, let's create a midplane between two planes construction plane using the front and the back of the component.
05:22
Then we'll start the Extrusion and base it on this new construction plane,
05:28
creating it symmetrical with its distance based on the 0.98 value in the other sketch.
05:36
This will give us all of the primary features of our model.
05:40
We can then add the Hole features, based on the information in the raster sketch.
05:52
When we're done, we can just simply get rid of the third-party reference, which is the raster portion of the sketch,
05:58
without losing any of the information that was brought in to Sketch 0.
06:03
There are a couple of different ways to approach using raster information to create a sketch inside of Inventor.
06:08
But this is a creative one that leverages the power of the raster design tools inside of AutoCAD,
06:14
and the ability to easily reuse any AutoCAD data you already have to build 3D inside of Inventor.
