27-10. Example10 Depict 3D Object Inwards Autocad

For this AutoCAD 3D example I volition endeavour to exhibit pace yesteryear pace how to depict a 3D object that is shown inwards the motion-picture exhibit below. This persuasion of the 3D Draw is SE ISOMETRIC view. Note, In this event of tutorial I used: BOX, EXTRUDE, SUBTRACT, UCS, SE ISOMETRIC VIEW, FRONT VIEW, MODELING Toolbar,

First on the drawing refer to the angles as well as expect the 3D draw. We tin notice that this 3D object tin last drawn inwards several ways. We tin depict starting the 3D object (BOX - rectangular) as well as nosotros tin depict it maiden off inwards 2D alongside drawings, hence Extrude as well as Union etc. I volition start instantly alongside the 3D object hence I'm using the EXTRUDE ascendency as well as SUBTRACT command, subtract parts of the basic 3D object.

Well earlier the start of the drawing, let's larn written report which are all the views nosotros involve for a improve agreement of the 3D object itself as well as when nosotros are to subtract certainly parts from the basic ane that yous know how to follow the steps of this tutorial.

So nosotros receive got the next views on the object (Top view, Front persuasion as well as Right view).

Of course of written report these views may last dissimilar as well as everything depends on how yous started to draw. This persuasion of the 3D object (picture above) is SE ISOMETRIC view.

This is a expect at the 3D Draw (see paradigm below) is SW ISOMETRIC.

Step 1.

So let's drawing a 3D object alongside outer dimensions of 90x60x50 inwards SE ISOMETRIC. UCS is in  master WORLD position. If yous produce non know how to seat the UCS expect at the UCS Toolbar.

Now let's larn alongside the BOX command from the MODELING toolbar depict 3D object cuboid shape.

Command: _box
Specify maiden off corner or [Center]: [click, left mouse push clit on the desktop of the drawing]
Specify other corner or [Cube/Length]: L [we create upward one's hear that 3D object volition last drawn yesteryear dimension input]
Specify length <80.0000>: l [the length of 3D object]
Specify width <75.0000>: ninety [the width of the 3D object]
Specify summit or [2Point] <40.0000>: sixty [the summit of the 3D object]
Command: ESC

Now nosotros receive got a drawn 3D base of operations object.

Step 2.

If yous expect 3D draw of a finished sort yous tin notice that inwards 2 ways nosotros tin depict objects which nosotros volition take away (Subtract) from the base. We tin function over TOP view or FRONT view.

I worked over FRONT view. So considering the dimensions I drew 2 rectangles using the RECTANGLE command, at the ends of a 3D object which I volition later on expand the EXTRUDE command as well as and hence cutting off alongside SUBTRACT command.

Command: _rectang
Specify maiden off corner shout for or [Chamfer/Elevation/Fillet/Thickness/Width]:
Specify other corner shout for or [Area/Dimensions/Rotation]: D
Specify length for rectangles <10.0000>: 15
Specify width for rectangles <10.0000>: 60

Now I receive got a province of affairs similar this inwards the motion-picture exhibit below.

Step 3.

The side yesteryear side pace is to create a 3D object from our rectangle that nosotros volition extrude. Make certainly that yous receive got non touched position UCS. Then click on the EXTRUDE ascendency on the MODELING toolbar as well as and hence direct the rectangle as well as press travel into to type the value -30.

Why is the value inwards minus (negative)?
Minus (negative) because if nosotros expect at UCS position as well as hence nosotros uncovering that our Z axis positive inwards the contrary direction of what nosotros involve to extrude our rectangle. If nosotros larn below the plane, consisting of the X-axis as well as Z-axis (or Y axis as well as Z axis) as well as hence the value is minus (see COORDINATE SYSTEM).
Do non confuse the 2D coordinate system. In 3D drawing, nosotros also receive got a Z axis as well as it is e'er inwards combination alongside the X axis or the Y axis hence ane time again nosotros receive got ane plane. (XZ or YZ).

Why the value 30?
So receive got a expect at the dimensions of the drawing. If the full width of the 3D object is ninety as well as nosotros receive got a department that is dimensioned yesteryear the value of sixty as well as hence the calculation is uncomplicated (90-60 = 30).

Step 4.

The side yesteryear side pace is to take away a role of the base of operations object, using the SUBTRACT command. So nosotros subtract reddish 3D objects, from the base of operations of yellowish 3D object. So, click on SUBTRACT command as well as subtract reddish objects. If yous produce non know how, as well as hence yous receive got non read this spider web tutorial from the beginning. See the SUBTRACT command.

Now nosotros receive got this province of affairs every bit inwards the paradigm below.

Step 5.

The side yesteryear side pace is to subtract role of the basic 3D object on the other side. Of course of written report ane time again the same actions but this fourth dimension the view is RIGHT as well as nosotros blueprint rectangles of 40x20 (90-50 = 40, as well as dimension twenty nosotros seen on the finished drawing).

Command: _rectang
Specify maiden off corner shout for or [Chamfer/Elevation/Fillet/Thickness/Width]:
Specify other corner shout for or [Area/Dimensions/Rotation]: D
Specify length for rectangles <90.0000>: 40
Specify width for rectangles <60.0000>: 20

It looks similar this inwards the motion-picture exhibit below. Here, notice that I receive got drawn the rectangles straight to the SE Isometric View.

Step 6.

The side yesteryear side pace is the creation of other reddish 3D object, which volition later on extrude. Make certainly that yous receive got non touched seat of UCS. So, click EXTRUDE on the MODELING toolbar as well as hence direct the rectangle as well as after pressing the travel into keys, type the value -50. Study the motion-picture exhibit below as well as notice the direction of the Z axis.

Step 7.

The side yesteryear side pace is subtracting reddish objects from the basic yellow. So click on SUBTRACT command as well as subtract the respective objects. If yous produce non know how as well as hence yous receive got non read this spider web tutorial from the beginning. See the SUBTRACT command.

Now nosotros receive got the in conclusion layout of our AutoCAD 3D Draw.
