Creating 3D Isometric view of various structural elements in AutoCAD

1.Aim & Introduction

Aim

This challenge aims to let the student utilize the tools in Autocad to create a 3D sketch. It aims to help the student familiarize with thedifferent 3D commands present in the AutoCAD software. This challenge aims to correlate the 2D drawing into 3D sketches

Introduction

The AutoCAD software provides different tools. used in this challenge is as described below:

Line- creates line object

Polyline- creates rectangle line object

Rectangle- creates rectangles object

Circle- create circle object

Trim-Cut unwanted lines or shapes with the provided cutting edges

Extended- Extend lines to opposite corners

Move- Move objects to particular locations

Copy- Copy obejects to particular locations

Rotate- Rotate selected objects to a particular angle with respect to base point

Array- Copy an object in a set path linearly or polarly

Join- Joins separated line objects to a particular angle with respect to base point

Dimlinear(DLI)- provides vertical or horizontal linear/ straight dimensions

Dimligned(DAL)- Provides dimensions with respect to the angle of the object

Dimangular(DAN)- Provides angular dimensions between two line objects.

Quicklinedimension(QDIM)-provides quick dimension of a geometry

Leader- creates an arrow head line

Layer- Provides identification of line or object groups by their properties

Units- Open "Drawings Units" window to specify to modify the dimension properties

Hatch- provides hatching pattern in a given object or internal point

3D orbit- allows panning in the 3D view

Extrude- Creates a 3D solid, surfaces, or 2D regions by subtraction

UCS- Manages defined user corodinate systems

Union-Unions two solid or two region objects

2. Sketch and procedure:

A. Create a 3D Isometric View of the Building with plan and elevation given

PROCEDURE:

• Draw the 2D plan

• You can use the Top view for better view

• Extrude and change the elevation

• Go to left view and add the window. Extrude afterwords

• Extrude and trim

• Do the same procedure again

• Then substarct

• Add 3D face for the window glass

• Do the same for the other window

• Substract

• Add dimension to finish

Result:

B. Create the 3D view of the building facade as given in the plan and elevation. Also, see the detail of the window

PROCEDURE:

• Create 2D plan

• Extrude

• Go to the plan and draw the window opening

• Move to the correct location

• Subtract the solids

• Create the top part

• Copy to 4 sides

• Then union them all together

• Go to front view and draw the window detail in 2D

Results:

C. Create the isometric 3D view of a stair with railing a shown in the plan and elvetion , Assume the size of the balustades and the handrils

PROCEDURE:

• Create the 2D right side view

• Fillet with radius 0

• Go to isometric view and extrude

• Draw the handril

Result:

D.Create the 3D view of a Wall with spread footing . Create the Door opening only. Assume the size of the parpaet and the coping. See the plans and elevation for the details. Also, create a rendered view of the model with materials as of your choice.

PROCEDURE:

• Proceed with the 2D plan

• Change the elevations

• Extrude

• Go to front view

• Trim and join

• Sketch the canopy

• Extrude

• Create views

Results:

3. Conclusion

The Autocad software allows 3D sketches where solid objects or 3D surfaces are present. By using 3D function of the Autocad software one can illustrate or convert a 2D sketch into 0 3D illustartion
