Click on the trace bitmap option.

Power trace window gets open now click on ok. The background of the image is get separated from the main file.

Now pick the image and place it in the black place. Click in the background and select the color and click on 'color eyedropper' and place the color by simply clicking in the background.

Open the software. The window get open on the screen.

Before going for the actual, go to View. Make sure we have selected the custom view and 100% zoom view(i.e. Zoom 1:1).

Now select Align and distribute objects option. We can see the corresponting window on the screen. Here select Last select option in the align menu. This means the alignment is get applied to our last selected portion in the design.

Select Fill and stroke option to get various effects of color in the design, like color gradient. Here we can also change Opacity i.e. to change the color darkness of the object.

Now to start the designing select circle from the left hand side in the window. Bring the pointer inside the working space Hold Shift+ctrl on the keyboard and drag the mouse to get exact round circle. Select the black color for the circle. Bring the opacity to half i.e. 50%. We can see the black color get lighter(gray).

Then click on the select option. Right click on the base circle and select Duplicate option from the drop-down list to get the exact copy of the circle. For identifing the difference in the original and duplicate circle make the second circle red.

Again right click on the red circle and get its duplicate copy. This time make the circle blue.

Bring the blue circle to the half as shown in the image below.

We have selected the blue circle. To select red one hold Shift and click on the red circle.

Then go to Path menu and select Difference option in the drop-down list.

We can see the result as ahown in the right side image. When we select a pericular portion and click on the difference option the portion is get cut.

Then again right click on the half red and select duplicate option to get its copy. To get the difference make it blue.

Flip the object horizontally. Then align the object to right sides by selecting the option Align right sides.

Again get a duplicate copy and make it green and rotate the selection to 90 degree counter-clockwise. Then click on Center on vertical axis to get the result as shown in the image.

Follow the same steps for getting half yellow circle shape.

Now select the base black circle and drag it to the side so that we can see the actual design clearly. At last select the whole sketch and click on the group option. To combine all different parts in the design.

As we know inkscape is a vector deigning software. The designing created in the software has a pixle. For removing this click on the red portion and hold shift and click on the yellow half circle and click on the dfference option in the path menu. Follow the same steps for all color.

If we want to creat a 3D view in the inkscape we can select the gradient view. For the detail procedure please refer the video tutorial I have mentioned above. This is one of the effect we can give in this software to get more effective result.

Then for getting the shadow use the following steps.

Right click on the red color and select duplicate option and make it black to get the difference. Bring the opacity to 50%. Then again click on the black color to get round arrow.

Also we can see the cross(+) symbole. Bring that cross at the corner.

And drag the curve arrow down, so that it can be get inserted in the green color as shown in the below image.

Right click on the green color get a duplicate copy of it.

Then hold the Shift key on the keyboard and click on the black color.

We can see the change as shown in the below image.

To select a perticular portion of the black color to get a shadow and select intersection option from the Path menu.

Follow the same steps for getting the shadow for all color.

Finally we get the result as shown in the below image.

Select the sketcher option in the tool menu.

Sketch the object in the center.

Go to part design. Creat the body in the model tree and apply pad command to the sketch.

Apply the same commands for extruding the next sketch. Here we select the face of the previous extruded object and draw the sketch on it.

Select the sketch option in the window.

Sketch 2D design first. Make sure our object is in black color it shows that our design fully constrains.

Design simulation can include the analyses of 3D designed objects that virtually test the behavior of a product under various operating and environmental conditions. This is an alternative for the trial-and-error method in prototyping, which is very cost- effective. The smart simulation process provides the targeted implementation of design choices in various stages of the development cycle.

Go to Simulation wrokspace. The window get open which shows different types of stresses like, static stress, model frequences,...etc. These stresses are nothing but the effect of applie load the object.

In simulation we check the behavier of the object under different applied stress conditions. To know the basic condition of object under stress I have selected static stress.

This stress is work under the vertically applied load on the body.

For simulating the object we need to know the material of object in reallife which we have designed in software. So, I have selected steel.

The second thing that we need to select is the Mesh. This option is important in the case where we require the accurate result of simulation process.

Right click on mesh option in the model tree and select Mesh settings. The window gets open on the screen, where we have to do some settings of mesh.

Here we need to set the model base size. There is the dragging bar with ranges from 1% to 10%. I have taken the size as 5%.

The mesh generated around the object is nothing but the columns get created around the object which calculates the concentrations of applied stress in that area.

In this case accuracy of the result is depends upon how much mesh is smaller or concentrated. Hence, I have selected the mesh concentration as 5%.

Again go to the mesh option in the model tree and right-click on the mesh and select Generate Mesh option and we can see, the software generates the mesh-like a fishing net around the object.

The next thing that we need to do is. Applied the constraints. By applying constraints we can fix the position of an object in the space. It is helpful for the software to apply the stresses around a certain point. So I have tie the object the wall.

Now we need to apply the load on the object. Click on the load and the window get open on the screen. In this window, we can see the different types of loads on the list.

I have selected the Force option and have selected the outer surface of the object. Due to which we can see the bunch of arrows on the surface of the object.

In this window, there is a flip arrow option by which we can change the direction of the arrows. This depends upon the direction of the applied force and here we have to choose the value of applied force. Let say 3000N and click ok. Now we can see the certain change on the window that it has a green checkmark.

Now go to Solve option different option get open on the screen which asks us to run this locally or on a cloud. So I have chosen the Locally option and click on Solve. Again the window gets open which shows the status of the job to get the result of simulation.

Now here the process of simulating our object is done. It cames with some results but it is difficult to understand it. In the window it shows the Actual minimum safety factor.

We can see the stress concentration points in the below image.

And in the image below we can see that how much our object will move under applied force.

Above image shows that how the object will get fail gradually at different stages.

Here the failure stages are shown in the forms of various colours.

Like Blue colour shows the less possibility of failure. and it gets increases gradually upto Yellow colour. At Red it becomes most critical stage of failur of object. This will shows the how much our object is sustaiable.

For rendering an obeject first go to the Render environment. Here our original object is open. Rendering is uses to present our object in an effective manner. So, if we want to do some changes in our actual object it is not possible for us after rendering the object.

So first go to save as option and change the name of the file. Now we can see the dublicate file of the original object on our screen.

When we open the render environment we can see the change in our object. It seems like more photo realistic model.

As we can see in the image the appearance option is get open on the screen. By appling this option we can see how our object will

To show that how our object will look in actual life. It shows the object distributed in granules. This is calle 'In-Canvas Render' It shows the condition of object after actual manufacturing.

By appling Animation we can show the movment of the object in the space. This option is helpfull where we require to show the motion of object. Here I have used this option for study perpose. Refer this vedio for Animation of the object.

In the animation window at the bottom we can see the Animation Timline. If if do some movment of the object it is get recorded in this timeline and when we play it the film is get played on the screen.

In this week we have explored our knowledge of 3D and 2D designing with different software.

I also get the difference between ‘raster’ and ‘vector’ software’s and their different features.

Every software either 3D or 2D either ‘raster’ or ‘vector’ have their advantages and disadvantages.

I have explored myself more with 3D software because I am a ‘Mechanical engineer’ and this software will help me a lot with 3D modeling and lots of many things.
