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

Sketch and procedure:

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:

Create the 3D view of the building facade as given in the plan and 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:

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:

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

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
