By the end of this unit, you should have created two parts for the cross halving joint, assembled them and fully rendered the completed drawing!
After double clicking on the Inventor Icon on your desktop, this screen will appear 2. Double click on the Standard ipt 1. Click on the Metric Tab
3 – This is the Browser Bar – this shows the model history and allows you to modify your model 1 – This is the Standard Toolbar 2 – This is the Panel Bar Area – it controls most of the Part features This is the 2d–Sketch Panel. This is where you will do all of your sketching and dimensioning in 2D.
To get started we will draw the side profile of one part of the base. The only tool needed is the line tool. 1. Single click the line tool 2. Click on the Origin point in the centre of the screen 3. Check that these numbers are set to zero.
It is useful to use the mouse wheel to zoom out so that you can see the full line. Draw a horizontal line. Your teacher will show you how to check the ‘Horizontal constraint’ Make sure it is roughly 145mm
The screen is shown in white so that you can clearly see the dimensions Draw a box which is roughly this size Make sure you see the green ‘Auto constraint’ symbol when completing the box Once finished, make sure you Right click and select ‘Done’
Click on the dimension tool Hover your mouse over the line you want to dimension so that it turns red Click on the line and drag and drop the dimension line anywhere on the screen 1. Single Click on the dimension line and change the value in this box to 145mm 2. Click the green check box There are two ways to dimension a line. In this way, you will simply click on the line that you want to dimension and then drag and adjust the value.
Finish dimensioning the rectangle so that it looks like this Once finished, right click and select Done. This is Very Important
You are now going to use the line tool to draw two rectangles as shown. Add dimensions as shown
Lets use the line tool to draw in some diagonals Make sure you click on the corners so that the green constraint symbol shows Don’t forget to Right click and select ‘Done’ when you are finished
2. Then Select the Construction Line tool We are now going to set some of these lines to construction lines so that we can complete the profile Select the line by clicking on it
Repeat this process so that all these lines are construction lines Remember to deselect construction lines when finished
Using the line tool, complete the profile Draw these three lines at this point here
Dimension the three new lines as shown To complete the profile add in the last three dimensions Don’t forget to Right click and select ‘Done’ when finished!
We are now ready to finish the 2D Sketch and enter the 3D Modelling environment Right click on the screen and select ‘Finish Sketch’
The 2D Grid disappears and the panel bar changes to ‘Part Features’ The panel bar has changed to show 3d modelling tools
Lets change the view to Isometric. This is always a handy view to view your model in. Right click anywhere on the screen Select Isometric view
Click the extrude button We will use the extrude feature to make our model 3D
Inventor automatically selects the profile we have drawn and extrudes it 10mm. A preview of this is shown on the screen 1. Set this value to 45mm 2. Click OK
Congratulations you have made your first part in Inventor Use the Toggle View tool to view your model at a different angle
Now its time for you to take control. Open a New ‘Standard Part, ipt’. Referring to the previous instructions . Create the top part of the cross halving joint. Use the drawing below for dimensions.
Your completed drawing should look like this Remember to save your work as ‘Top Cross Halving’
We are now going to look at joining our two parts together by using an assembly drawing. Select the ‘Standard iam’ template Make sure the metric tab is selected Select OK Assembly
We are now in assembly mode. Everything is just about the same… This toolbar is called the ‘Assembly Panel’ and has some different functions on it
1.Select ‘Place component’ 2.Select ‘Base cross halving’ Lets place our first component
We are now going to look at joining our two parts together by using an assembly drawing. IMPORTANT! Press escape on your keyboard so that you don’t create two of the same component!
Now place another component just as before. Insert your ‘Top Cross Halving’ file….
We now need to join the two parts together so that they are assembled and cant be moved on their own. To do that we use ‘Constraints’. Select the Constraint tool. In total we will place three constraints on the parts.
The Constraints tool asks us what faces we want to join together. This is also called ‘Mate’ 1. This button here is pressed in and it wants you to select the first face to ‘mate’…. 2. Click on this face here
1. Now it is asking you to select the second face… 2. Click on this face here ( make sure it is the top joint)
It now looks something like this… Lets select the next two faces to join together Click apply to finish the constraint
This is the first face to select The second face is behind here – so you will have to rotate the drawing so you can see in behind… Here is the second face Mate the two surfaces together
Almost there. For the last constraint we will make sure that the top surfaces are in line. This is called ‘Flush’ 1. Select the Flush command 2. This is the first face to select 3. This small face is the second face to select Apply the constraint to finish
Congratulations! You have completed your first assembly! Rotate your work so that it is roughly in this view SAVE YOUR ASSEMBLY! Save as ’Mug Tree Assembly’
Rendering with Inventor Studio Select ‘Inventor Studio’ from the Applications menu Open your ’Mug Tree Assembly’ file… Our page is the same as usual but with a new ‘Inventor Studio’ toolbar that will help us render
Lets look at surface styles This button will apply the style Change the material by selecting any one of these. REMEMBER – the Mug Tree is made out of Wood! You can change options like ‘Shininess’ in these menus IMPORTANT – Make sure you have selected your model so that you can change the Surface Style
Lets look at Lighting styles Select any type of light. If it asks to ‘Save the changes’, select ‘Yes’ Select shadow type Set how bright or dim you want the light to be Save your changes
Lets look at Scene styles Select ‘XZ Reflective GP’ Select colours for your Gradient background The Environment tab, allows you to change Shadows and Reflections
Finally select Render Image Select the Perspective camera for a more Pictorial view Make sure that you select the XZ Reflective GP You can improve the quality Select Render
Congratulations! You have completed your fully rendered drawing. Make sure you save the picture!
