# Step-by-Step Guide to Creating the Internal Space for Your 3D Model: A Detailed Transcription
This guide is based on a detailed transcription of a video tutorial. The focus is on creating the internal space of a body in 3D modeling software, using sketches, cutouts, and transformations.
---
## Introduction
Good afternoon, dear friends. Today we will learn how to create the internal space for our 3D model. This process involves making auxiliary drawings, sketching cutouts, and ensuring proper dimensions for the final design.
---
## Step 1: Making Auxiliary Drawings
The first step is to make an auxiliary drawing on the side of the body. To do this, we will temporarily hide it on the face of the body. The top face of the body needs to be sketched so that we can avoid redrawing its edges. For convenience, you can use the elongated cutout element and the thin-walled element tool. These tools will allow us to create a protrusion for future roofs and immediately draw a contour for the body.
---
## Step 2: Creating Cutouts
To make a cutout at a distance of 3 mm from the surface, we need to use the reverse direction. This ensures that the cutout is inside the body. We will also create a new sketch on the same face and transform the objects using an elongated cutout.
- Select the edge and make a 3 mm indent from it.
- Check that everything is cut out correctly.
- Confirm and make another cutout on the same edge, following the contours of the main body of the lower part of the body instrument.
---
## Step 3: Adding Conditions and Dimensions
For this, we will create a new sketch and add conditions by selecting a point using the Ctrl key and holding a straight line. This will ensure that the width of the sketch size is observed.
- Select the line of interest to us and indicate a distance of 3 mm.
- The same element should be an elongated cutout at a distance from the surface.
- Indicate the target surface of the bottom of the case to confirm that we have received a niche for the location of control elements for the controller motors.
---
## Step 4: Checking Wall Thickness
After performing these operations, it is essential to ensure that the walls of the case are of sufficient thickness when printing. For this, we can use the cut tool and check exactly the cross-section of the part.
- Drag the right mouse button upward, select the dimensioning tool.
- Select the line of interest to us and indicate a distance of 3 mm.
- Check that there are no thin elements anywhere.
---
## Step 5: Placing Holes for Drive Components
Next, we will place the hole for the drive sprocket and attachment points for the main rollers and torsion bars. To do this:
- Return to the sketch for the part located behind the body.
- Change the conditions for the location of the existing sketch.
- Create a new reference geometry on the plane in front using the insert tool.
---
## Step 6: Creating Reference Geometry
For this, we will create an independent plane independent of the body. Measure the distance (45-48 mm) and build a reference plane at a distance of 45-48 mm from the edge on the plane in front.
- Create a new sketch on this plane.
- Draw circles using the equality relationship to give them the same diameter.
- Transfer these circles to the reference geometry.
---
## Step 7: Adjusting Sketches and Creating Arrays
We also need to adjust the sketches for the rollers. Note that the attachment points of the rollers on the left and right sides are offset from each other due to the suspension torsion bars passing through the body.
- Draw the rear roller on the same line, moving it 638 mm.
- Use the linear array tool to create a circle in accordance with an auxiliary drawing.
---
## Step 8: Beveling and Final Adjustments
Finally, we will make a sketch that repeats the bevel line. For this:
- On the right plane, create a sketch that transforms the point of the bevel.
- Draw the profile of the future cutout using dimensions and indicate an angle of 45°.
- Use the elongated cutout tool to bring the cutout to the top and apply changes.
---
## Conclusion
After performing all these operations, we will have created the internal space for our body. We can now review the final design and ensure that there are no errors in the cutouts or walls of the case. This concludes our detailed guide based on the provided transcription.
