3d drawing tutorial in autocad

This is a invitee post past Andreea Georgiana. She is a CAD enthusiast who likes using the power of Computer Aided Blueprint to create absurd useful designs, from conception to 3D press. She has a 21-day AutoCAD course at tutorial45.com.

She says, "Being able to utilise Computer Aided Design software to bring your ideas to life is one of the things I totally disagree simply engineers should be able to do. With the numerous advantages of being able to move past the level of a 3D model to actually having the model 3D printed, anyone should consider learning at to the lowest degree the nuts of modifying a CAD model.

"Every bit a CAD hobbyist, wife and mother, I have found many cases where a customized solution designed myself has solved a problem in the exact manner I wanted, cheers to the power of CAD and 3D press. You tin discover some free tutorials here."

Earlier I showtime, here are 2nd and 3D images of the model you'll draw in this tutorial,

Use the images in a higher place to assist you in completing the 3D model.

Phase i: Depict the pipe (circles) and legs (lines)

Make sure the Quadrant and Midpoint in Objects SNAP settings are on. The upper parts of the legs are snapped to the left and right quadrants of the model. Later, y'all'll utilize the Midpoint OSNAP.

So follow these steps, following the image to the correct and below:

1. Draw 2 concentric circles with R20 and R14.
2. Draw a vertical line downward from the left quadrant of the outer circumvolve 24 units long
3. Draw a horizontal line of 8 units toward the left using the lower end of the vertical line you lot just drew as the starting bespeak.
4. Draw a vertical line of half dozen units down from the ending indicate of the previous line
5. Depict a horizontal line of 12.4 units rightward from the ending bespeak of the previous line
6. Draw a vertical line of 1.half-dozen units up
7. Describe a line of ane.6 units to the correct

At present follow these steps to trim and mirror the model:

1. Use the TRIM command to remove the unnecessary part of the circle. Use the 2 lines that run into the circle every bit the cutting edges and the part of the circle between them as the object to trim.
2. Now mirror this left side using the center of the circle to create the similar shape on the right side of the circle.
3. Trim information technology to complete this step using the TRIM control. You lot should end upward with an image similar to the one below

Stage ii: Pause the circles at the height

Follow these steps:

1. Use the Upper quadrant of the inner circle to describe a vertical line that crosses the outer circle. The length of the line does not matter.
2. Use the Showtime control with the Outset dimension set up to 1 units to depict 2 lines on each side of the original line.
3. Now delete the primal line.
4. Use the EXTEND command to extend the remaining lines to the inner circumvolve. You might need to zoom in to notice that they don't actually intersect with the circumvolve.
5. Use the TRIM command to trim the ii circles every bit shown in the image beneath.  Use the lines equally the cutting edges.

Stage 3: Add the summit

Follow these steps:

1. Apply the Beginning control to commencement the left line to the left and the correct line to the correct with an offset distance of 6 units.
2. Trim the new outer lines using the outer circle as the cutting border., Then trim the top part of the outer circle using the outer lines as the cutting edge.
3. Yous desire the outer lines to be 7.ii units long, as shown on the image beneath and and so and you need to shut the caput using a horizontal line.
4. One way to do this is to start the LINE command, type from on the command line and fix the showtime to 7.ii, moving your cursor upward. The draw the LINE horizontally to the left until it intersects the outer vertical line on the left. Then trim the parts of the line that extend past the new horizontal line and trim the function of the horizontal line between the ii inner vertical lines.

Stage iv: Add the bracing (triangle)

Design the fiddling triangle on the side of the model by drawing a vertical line of 24 units, a horizontal line of 8 units, and and then closing the triangle. For now, put it out to the side, separated from the main model. Yous can depict on top of the existing lines to start, close the triangle, then select each of the 3 lines and move them to the right.

Stage five: Fix for 3D conversion

Use the REGION command and select everything on the drawing area to form 2 regions.

At this betoken, if you lot aren't using a 3D workspace, y'all should switch to one. Click the lilliputian arrow to the right of the Workspace Switching icon on the lower-right corner of the AutoCAD window and choose 3D Modeling.

Phase 6: Change the view and extrude to 3D

Navigate in 3D using Gratuitous Orbit. Click on Free Orbit in the navigational bar at the right, click on your mouse, hold, and move until you get  a 3D view something similar the ane yous run across here. You can drag on the "orb" and its round handles to get the right view. A keyboard shortcut might work for yous: Hold down the Shift key and click and elevate with your mouse'southward middle (scroll) push.

Use the EXTRUDE control to extrude the model by 28 units and the triangle by half-dozen units.

On the Visualize tab,  in the Visual Styles panel, click the Visual Styles drop-downward and choose Shades of Gray.

Phase seven: Assemble the model

Follow these steps:

1. Using the View cube at the upper correct of the AutoCAD window, switch to the Meridian view (or go to the Visualize tab, Views panel, and click Superlative.)
2. Use a regular 2D mirror command to mirror right triangle so that you take ane on each side of the 3D model.
3. At present employ 3D orbit over again to get a view like yous see here.
4. 
5. Utilize the Movement command to motility the triangle from the midpoint of its upper edge to the midpoint of the 3D line on the circumvolve quadrant. as shown in the image here.
6. Turn the view once again so you tin come across the left side of the 3D model and move the left triangle in the same manner.
7. Starting time the Wedlock command, select the iii objects, and press Enter.

You lot have just merged the iii object to course 1.

Phase eight: Add mounting holes to the base

One nice thing with AutoCAD when you model in 3D is that you can all the same use the ability OSNAP and draw second lines that will help you design in 3D.

Follow these steps:

1. View the model so yous can create the diagonal lines shown on the image at the correct. Use the Endpoint OSNAP for the start and end points. You'll accept to alter the view several times as you draw the lines.
2. Create circles using the midpoint of each of the lines you merely created as the heart and a radius of 2.
3. Extrude the circles down and then the height goes completely through the model. Y'all can select and extrude them all at once.
4. Subtract the 4 cylinders from the model. Start the Subtract command, select the model and press Enter, so select all of the cylinders and press Enter.
5. Delete the diagonal lines.

Phase ix: Fillet the sharp corners

The FILLET command will assistance you round some of the sharp edges. Follow these steps:

1. Select the edges with the cerise marker.  To make it easier to select just the edge, on the Dwelling house tab, in the Selection console, cull Edge from the Filter drop down. (Y'all might encounter No Filter, Vertex or Face before you make this selection.)
2. Use the FILLET control to round their shape with a dimension of R = 0.eight units. To FILLET, starting time the command, select the appropriate edge, enter 0.viii, and press ENTER 2 times.
3. Repeat the process with the contrary edge.

Phase x: Add holes in the peak

This is the final phase. Follow these steps:

1. Draw the line shown on the epitome below using the midpoints of the two edges.
2. Create a circumvolve of radius ii units using the center of the drawn line.
3. Delete the line you but drew and create 2 lines using the quadrant of the circle and two edges you previously used. You might have to rotate the model to find the object snaps.
4. Now, use the eye of those lines to create 2 circles of radius 2.
5. Delete the lines and extrude the iii circles using the EXTRUDE control and make sure they go all the way through the model.
6. Subtract those cylinders from the 3D model using the Subtract command.

Congratulations!

You should finish up with the following model. You might demand to FILLET few more edges to accept your model look identical to the model on the exercise. I hope this has been helpful to you!
