- [size=0.875]In clear space in the design window left click and drag[size=0.875] downwards to add the chamfers and (either during or after the drag action) type 1 to set the chamfer to a 45 degree 1mm feature
- [size=0.875]Save your file as HOLED CUBE.
[size=0.875]The HOLED CUBE is now complete SECTION 3 - Assembling cubes- Open DesignSpark Mechanical and close the welcome screen
- Ensure your PIN CUBE and HOLED CUBE designs are open (Link to cube models: http://designspark.com/eng/knowl ... hanical-tutorials-2)
- Create a new file containing both parts by triple clicking on the PIN CUBE and using the Copy command from the top left on the ribbon bar (remember: triple click select only selects item as a solid - to select devices with their component details you should either select from the structure tree or use the select component tool)
- Left click into the HOLED CUBE design and use the Paste command to place the PIN CUBE into the design (the imported model will often coincide with the existing model to some extent at this stage – this is not a problem)
- Save the file as CUBE ASSEMBLY
- Select the Move function from the ribbon bar. [size=0.875]A move anchor[size=0.875] will appear in the model with 3 coloured axial arrows. Left click and drag[size=0.875] one of the arrows to move the imported cube away from its partner shape so there is clear space between them
- [size=0.875]To assemble the cubes together as they would physically appear you will need to use the Move, Up to[size=0.875] function a number of times to position the cubes in the nominal x[size=0.875], y and z[size=0.875] axes. While the cube is still selected for Move[size=0.875], grab the central boss of the Move anchor[size=0.875] and position it so it sits on a face of the cube which you wish to align with the partner cube. Left click[size=0.875] on the arrow of the Move anchor[size=0.875]which sits in the axis you need to use to do the first align. A command icon menu will appear. Left click[size=0.875] on the 3rd[size=0.875] icon (a green arrow pointing at a rectangular sketch frame) and then Left click[size=0.875] on the face of the partner cube which you wish to align with (a point or edge can be selected as long as they sit on that face). The two faces should now be in line.
- [size=0.875]Repeat the above step until you have matched all 3 axes of the cubes. They should now be assembled.
- [size=0.875]To expand the assembly, create additional cubes of each version by triple clicking, copying and pasting [size=0.875]and assemble them together in the same way as above.
SECTION 4 – FILL TOOL[size=0.875]The Fill tool is designed to remove features from models and replace them with surrounding geometry. [size=0.875]In many cases it is clear and obvious how to do this but, in some cases, care is needed to ensure it is clear what is to be removed and which geometry is to be used to replace it. [size=0.875]Also, the Fill function can either be activated after selecting a feature on the model, or before. If the Fill tool on the Ribbon bar is clicked on whilst no part of the model is selected then the tool will remain active whilst repeated fills are carried out (using the Enter key to complete each fill in turn). In contrast, if the Fill tool is clicked on when a part of the model is already selected, the tool will not remain active after the fill. [size=0.875]The following exercise will go through some examples so that the skills can be applied to future work. - Open DesignSpark Mechanical (and close the welcome screen)
- Open the HOLED CUBE model from the section 2 exercise (or access it from the knowledge items in DesignSpark.com)
- Left click on one of the rounded corners of the cube to select just that surface
- Press Fill on the ribbon bar. You should see that the geometry of the 3 rounded edges connected to that corner has been extended to remove the rounded corner (and the Select tool on the Ribbon bar has returned to active state)
- Click once more on the Fill tool on the Ribbon bar to activate (note that it remains active this time because there is no part of the model selected)
- Now Left click on one of the rounded edges between any 2 side faces of the cube and press Enter (you should see that the geometry of the 2 flat sides has extended to remove the rounded edge)
- Repeat step 6 on the other rounded edges to remove them (note that the Fill toolremains active for the sequence of actions)
- Now select (by Left clicking) one of the cylindrical surfaces inside the cube and press Enter. You should see that the cylindrical hole has closed off into a conical depression. This is because the Fill tool, as described in the preamble, has used the surrounding geometry to replace the filled feature, in this case the 45 degree chamfer.
- Left click on the Undo tool to reinstate the cylindrical hole
- Left click on the chamfered edge of the hole to select it
- Press Enter to remove the chamfer
