27-11. Example11 Depict 3D Object Inwards Autocad
How to Draw a 3D object inward AutoCAD, using the next commands: Line, Box, SE Isometric, Rectangle, Subtract, Osnap, Region as well as Extrude.
For this AutoCAD example, I volition demo footstep past times footstep how to describe a 3D object shown inward the painting demo below. 3D object is SE ISOMETRIC view (picture below).
For this AutoCAD example, I volition demo footstep past times footstep how to describe a 3D object shown inward the painting demo below. 3D object is SE ISOMETRIC view (picture below).
So let's sketch a 3D object, outer dimensions of 90x60x50 inward SE ISOMETRIC view.
Now let's purpose the BOX command, from the MODELING toolbar, to describe the 3D object of the foursquare shape.
Command: _box
Specify foremost corner or [Center]: [Left-click on the AutoCAD desktop to laid the foremost point.]
Specify other corner or [Cube/Length]: L
Specify length <40.0000>: 90
Specify width <80.0000>: 50
Specify summit or [2Point] <30.0000>: 60
Step 2.
The adjacent footstep is to written report the drawing as well as dimensions. We quest to start from somewhere cutting upwards pieces of the construction of the block, to acquire the ultimate 3D object appearance. Since this 3D object resembles a sort of house, let's cutting off the bottom of the "house" to acquire a "covered terrace".
For this AutoCAD example, I volition function inward SE ISOMETRIC view (although yous tin sack become from exceed to front end view).
For starters let's calculate 90-60 = 30, therefore i dimension of the rectangle that nosotros describe is thirty as well as the other is xx (as nosotros run into amongst the dimension value inward the foremost epitome of this tutorial).
The adjacent footstep is to laid the UCS to the airplane inward which nosotros volition describe a rectangle. You tin sack practice this using i of the buttons on the UCS toolbar. I'm using push clit no. four (Z-axis vector) on this UCS link.
Then nosotros quest a RECTANGLE command to describe the rectangle.
Command: _rectang
Specify foremost corner signal or [Chamfer/Elevation/Fillet/Thickness/Width]:
Specify other corner signal or [Area/Dimensions/Rotation]: D
Specify length for rectangles <10.0000>: 30
Specify width for rectangles <10.0000>: 20
Step 3.
The adjacent footstep is to extrude (convert) a rectangle into a 3D object. So amongst the EXTRUDE command, convert the rectangle to the 3D object (with depth -50), nosotros become to minus (negative) because it is the direction -Y (please run into 3D UCS on the link). After extrusion, subtract the scarlet 3D object from the basic yellow, ie SUBTRACT command.

Step 4.
The adjacent footstep is to describe a 3D object, which past times cutting volition practice the correct roof of our so-called "house". We volition practice this amongst the LINE command. From the correct exceed of the object's surface, nosotros volition describe a trouble downward dimension thirty (60-30 = 30). Then from the same top, describe the trouble to the left of the dimension xx (see the dimensions of the drawing inward the foremost epitome of this tutorial).
Then plow Off the ORTHO, as well as connect these 2 drawn lines (the OSNAP magnetic signal for Endpoint should live turned 'On'). Now nosotros acquire a triangle figure. This triangle, consists of to a greater extent than a lines as well as nosotros quest to convert it to percentage as well as to EXTRUDE it later.
So run the REGION command as well as guide all 3 lines to convert to i airplane ie. a express surface area (region). If this fails, endeavour the BOUNDARY command.

So run the REGION command as well as guide all 3 lines to convert to i airplane ie. a express surface area (region). If this fails, endeavour the BOUNDARY command.
When yous are converting lines to a region, therefore brand extrude 3D object using EXTRUDE command. Then, using the SUBTRACT command, subtract the scarlet 3D object from the yellowish 3D object.
Now nosotros accept this province of affairs every bit inward the painting demo below.
Step 5.
The adjacent footstep is to describe a 3D object, which is located to the left of the so-called roof as well as its cutt off.
This 3D object volition also live drawn using the LINE command. We volition describe lines of surely dimensions inward relation to the dimensioned drawing as well as connect the lastly trouble to the OSNAP Endpoint. See the painting demo below.
Step 6.
The adjacent footstep is to convert drawn lines to the percentage area.
I promise you've learned to a greater extent than lines converts to i line, as well as if yous did non therefore run into the EDIT POLYLINE tutorial. To brand surely yous created the percentage well, inward the Command Prompt trouble whether it says "1 Region created" or disable Layer past times which yous describe a basic 3D object (in my example, yellowish color), activate 3D REALISTIC VIEW as well as if your shut surface area is filled therefore you've created the Region well. It looks similar the painting demo below.

Step 7.
Return Layer to Draw the Base 3D model inward Drawing (Turn it 'On'). The adjacent footstep is to extrude the created percentage inward a 3D object. Again await at a dimensional drawing, The UCS was educate from the start as well as nosotros did non impact it (if yous are house it inward the airplane inward which the object is located created past times the Region command).
Let's run the EXTRUDE command as well as extrude the created region. Then purpose the SUBTRACT command as well as cutting off from a basic 3D object, a newly created object. It looks similar the painting demo below.

And finally our AutoCAD 3D object drawing, looks similar this inward the painting demo below.
