2. Step 1 • After opening inventor pro. • Click on new, on the task bar. • Make sure that standard.ipt is highlighted then click on create.

3. Set-up • To start up you will need to change the units you are working in. • First step to achieve this is to click on tools at the top of the screen • Next click on document settings • A submenu will pop up • Click on units • top of the submenu • Click on the drop bar under length and change it to inch then click apply

4. Step 2 • Click on the icon called box and a yellow triple plane should show up • After clicking on box choose one of the three planes to start your design

5. Step 3 • After choosing a plane to work on it will flatten to a 2D sketch make your box 1in by 1 in (to achieve this you must click on the center yellow dot after choosing the plane you want to work on then expand the square or simply type 1 then hit tabs and again type 1 then hit enter • After making this square you will notice that it will expand to a 3D shape of a 1in by 1in by 1in cube with an arrow and a ball next to it (this feature is called extrude) • The arrow will expand or shrink the box the ball will compress or expand the edge of the box play with it a bit then return it to normal and shrink the box to .0625in next hit enter.

6. Step 4 • Now that you have your square we can start to use the different functions of the toolbar section called modify • Adjust the angle of view so you can see one corner of the 3D square using the cube in the right hand corner of the screen

7. Step 4 cont. • Select a corner then click on chamfer and small sub menu will appear near that corner. • Next to the measurement part of the submenu in the middle of the screen you will see a drop bar click it and select the one that says 2 distances (the drop bar is next to the measurement input and above the button that says edges) this will cause the one arrow to turn into 2 arrows. • Reselect the corner and adjust the 2 distances so that one is .50 and the other is 1

8. Step 5 • Next adjust the view so you can see the other corner (across from the corner you just chamfered) you will have to flip the measurements so that the chamfer will work otherwise it will pop up as an error. • You now have the base of your heart

9. Step 6 • Click on the box icon again this time the yellow planes wont appear click on the object on the side that shows it as a triangle (it will not directly say choose a plane but if you leave the mouse alone it will say it near the cursor) • After clicking on the face it should rotate the screen and become 2D and outline your triangle move your cursor so that your new box’s center will be at .250 from the center of the base and .125 away from the triangle these will be either positive or negative depending on the side your base is on. (You can achieve this easily by moving the cursor to the base of the triangle then move it over till a dotted line appears going from your cursor to the other side of the triangle then move it down till a second dotted line attaches to the corner) (second arc you must scroll in so you can adjust the length to be perfect otherwise it wont attach.) • Make your dimensions on this box .5 in by .250 in so that it connects to you triangle but only goes halfway down it (again on the measurement parts simply type the dimensions so that the new bow connects to the original shape) • It should automatically extrude .0625in above the triangle this is a good thing just hit enter (if the box does not extrude to .0625 in then type it in on the measurement)

10. Step 7 • Next adjust the view to see the inside corner that is off of the base and then click chamfer. • Select distance on the submenu and adjust the distance to .125in repeat on the other corner then return to the original side to continue • Now we will use the fillet function of the modify bar • Select fillet and click on the first 2 angles that the chamfer had created and adjust the measurement to .500 (if after clicking on fillet it doesn’t work select one corner before clicking fillet then select the other after)

11. Step 8 • Now that you have the first curve you must filet the other 2 angles (the one from the chamfer on the other side and the new one from the first fillet) • This measurement should be set to .1875 (other measurements may seem to work but it will produce a slight but apparent jagged edge when you go to print) • you now have your first arc

12. Step 9 • While from one angle it may seem attached it is really above so to get them to be connected you must adjust your view to see the bottom of the image (so that the triangle is above the arc) • Next you will be using extrude, click extrude and a sub box appears click 2D sketch then click the surface then on the top click 3D model and click extrude yet again this should be already set to .0625 if not then set it that way

13. Step 9 cont. • Now your arc will be thicker than the rest which is a simple fix just change the view to see the raised section of the arc and repeat the instructions for extrude just instead of adding it to the raised section make the .0624 negative by using the arrow to shrink it to the same size as the rest of the sketch.

14. Step 10 • Now that you have made the first arc just simply repeat steps 6- 9 to make the second arc and you will have your heart.

16. The End

17. Thank you • Have fun and experiment more and create your own 3D design.
