VERO UK TRAINING MATERIAL Draft Analysis VISI Modelling – Draft Analysis INTRODUCTION Pre-requisite It is important that before you attempt this VISI-Analysis training example; you must have completed and fully understood the previous VISI-Design and VISI-Modelling and VISISurface Modelling examples During this exercise, it is assumed that the user has a basic knowledge of the VISI-Series software Object The following example will highlight some of the required techniques to fully utilise the dedicated analysis functions within VISI-Modelling Vcamtech Co., Ltd VISI Modelling – Draft Analysis Start by opening the workfile: File > Open Select the file named “Front Cover.wkf” The model should look as below: - The GREEN model will reside on the “Part 1” layer Part is to be used as the first revision of a plastic component There will be a second ORANGE model that resides on the “Part 2” layer The second model represents a second revision of the same component We will use the VISI-Comparison module to check for the model differences between Part and Part Switch ON both the “Part 1” and “Part 2” layer to show both models together Analysis > Compare Select the first body - Select PART ( the original GREEN solid model ) Select the body to compare - Select PART (the second ORANGE solid model ) NOTE : The comparison tolerance value can be changed from inside the compare control panel Vcamtech Co., Ltd VISI Modelling – Draft Analysis A new interface will be displayed (shown below) There are two methods of display for the new ‘comparison’ module The ‘Fast’ method allows the user to show all of the faces that are different between the two models to within a single tolerance The ‘Accurate’ method allows the user to identify all of the faces that are different between the two models and colour them with up to different bands of colour When the ‘Fast’ method is selected, modes of operation are possible: - Comparison detection method ‘None’ – The two models are shaded using the two colours No differences are detected The user can move the transparency percentage slider to observe the differences Vcamtech Co., Ltd VISI Modelling – Draft Analysis ‘Only common faces’ – Faces that are identical (to within the set tolerance) will be coloured in the ‘common’ colour Other faces will be coloured first or second colour as appropriate ‘Partially common faces’ – The models are coloured the same as ‘Only common faces’ above except, faces that have both identical and different areas will be ‘split’ coloured (i.e Common colour and first or second colour as appropriate) ‘External – Internal zones’ – This mode will activate the internal and external colour selection icons (and disable the basic first and second colour icons) The models will be coloured with the ‘common’ colour and the areas that are different will be coloured using the ‘Internal’ or ‘External’ colour depending upon whether the situation is ‘metal on’ or ‘metal missing’ Apply Update the display Set the detection method here The comparison tolerance is set here Differences less than this will be shown as ‘common’ The colours for the first and second models can be set here If ‘Show common zones’ is set, the complete model will be displayed If this option is switched off, only the different faces will be displayed Select the ‘Transparency’ option to activate a slider bar Moving the slider bar will dynamically show both models Moving the transparency slider bar will display both sets of faces on either model Vcamtech Co., Ltd VISI Modelling – Draft Analysis If you switch OFF the ‘show’ tick box in ‘Common zones’ and update the graphics, it is very quick and easy to see the design changes for the new revision of the solid model The design changes displayed without the common zones visible Now we know what the design changes are, CANCEL out of the comparison module by pressing the “X” We will continue to use the rest of the Analysis tools and work on Part (ORANGE model) Switch ON only the Part layer and also make it the current working layer (green arrow) Analysis > Draft Analysis Select the model to analyse – Select the ORANGE solid Select the plane normal – Select the Z axis (confirm using RHM) After selecting the plane normal a display panel will be presented to the left hand side Using this control panel it is possible to manipulate the draft angle values Vcamtech Co., Ltd VISI Modelling – Draft Analysis Load default Parameters – This will allow you to load the default angle range values previously defined Save Default Parameters – After setting the default angle range values, it is possible to save the values and recall them for another model Allows the user to re-select the direction for draft analysis Update graphics – Selecting this icon will update the display to represent any angle change Imprint Isocline curves – Selecting this icon will imprint the edges where each colour band changes onto the model Imprint Isocline curves and colour face sets – Selecting this icon will imprint the edges where each colour band changes and also maintain the face colours defined by the draft analysis control panel Draw Isocline curves – Selecting this icon will create wireframe geometry where each colour band changes onto the model WPL by Direction Will automatically create a new workplane based on the current draft analysis direction Angles evenly spaced – This option will automatically space the angle ranges evenly For example, if you choose divisions then the computed angle ranges will be 180°/8 (i.e 22.5° each) Vcamtech Co., Ltd VISI Modelling – Draft Analysis IMPORTANT : For this example, it is necessary to switch off the ‘Angles evenly spaced’ option so that we can manually define our own angle ranges Set the angle values to match the dialogue box displayed Switch off this After defining the angle values select the ‘Update Graphics’ icon If we look at the angle ranges defined inside the VISI-Analysis control panel we can see that any faces that are defined using a dark red colour fall between and -1 degree draft Any faces that are defined using a pink colour fall between -1 degree and -5 degrees of draft Using this graphical representation, we can see that the inner bosses are displayed dark red This indicates that we will need to increase the draft angle for these features Click on the ‘X’ to close Draft Analysis Vcamtech Co., Ltd VISI Modelling – Draft Analysis Modelling > Draft Faces Select reference edges - Select all outer edges of the inner bosses (E1) (confirm using RHM) E1 Select Draft Faces - Select all cylindrical faces of the inner bosses (F1) (confirm using RHM) F1 Vcamtech Co., Ltd VISI Modelling – Draft Analysis Select the Draft Direction – Select the Z-axis (confirm using RHM) Enter the Draft angle: -2 (minus) NOTE ! You will notice if you select the “Preview” button that the draft is added to the cylindrical face and the fillet radius at the base of the boss is also adjusted so it’s tangency condition is maintained There are other drafting options available, as your tutor for an example Vcamtech Co., Ltd VISI Mould - Creating Mould Tool Documentation Adding A Bill of Materials Using Assembly Manager Loading the File Lets begin by opening the starter file required for this tutorial Select the File | Open command and select tool-complete-plots.wkf Now that we have created some 2D drawings form the 3D mould tool assembly, the final task is to generate the Bill Of Materials using Assembly Manager The following exercises will show us how: For this task we will plan in advance how we want to organise our bill of materials For this particular mould tool we will divide the components in to logical families / groups of parts The following example shows the families we require and the order they should appear in the list: Mould Base Inserts Lifters Sliders Injection / Ejection Cooling Screws - Bolster Plates, Bushes, Pillars Any non-standard machined inserts Lifter Heads and Ancillaries Slides, Heals, Wear Plates, Rails etc Ejection Pins, Ejector guides, Sprue Bush etc Hose connectors, Plugs, ‘O’ Rings etc Screw Fixings Now we have decided how to break down the B.O.M lets begin the process in VISI using the assembly manager This can be started from the Annotation Menu clicking on the Assembly Manager Item The Assembly Manager Panel will appear on the right hand side, containing the list of parts and properties If you expand one of the Cap Head Screw Sums you can see the items beneath just show a list of “Cap Head Screws” Vcamtech Co., Ltd VISI Mould - Creating Mould Tool Documentation Info: - If you click on to one of the items in the sum, you can reveal the properties for each part Creating the Families for the relevant component groups The first real task we need to complete is to make the families for the components we discussed at the start of this section The next steps will show you how: - Right Mouse Click in the white area of the screen Select the Families > Create Family option from the menu Now create the Mould Base family and select OK The family will appear at the top of the tree as shown below Now repeat the task for the other remaining families so the tree looks like the one below This is how the tree should appear after the remaining families have been added Vcamtech Co., Ltd VISI Mould - Creating Mould Tool Documentation Adding Components to the appropriate Family Now that we have created all of the relevant families, it is time to add the correct components to each family The example will show you how to perform the procedure for one family and its associated components The Mould Base family will be used as the example: Drag and Drop all the items shown below into the Mould Base family Use the left mouse button to perform the drag and drop When using Drag and Drop on Sum items, you are required to select the items in the sum using multi select You cannot drag a Sum You can Multi Select items to drag and drop using the Select Elements option You should now have20 items in the Mould Base family, the display should look like the one below Having dragged and dropped all the items into the Mould Base family you should now have a total of 20 items in the family as shown Vcamtech Co., Ltd 10 VISI Mould - Creating Mould Tool Documentation Exercise – Organise the remaining Families Having now successfully organised the Mould Base family please arrange the remaining families to look like those shown below using the drag and drop method As you can see once we have consolidated all the families, the parts list becomes much easier to manage, your assembly manager window should be similar to the one shown below: - Seven Families should be present These items are part of the plot view (Masks and Profiles) This is the actual moulding, not required for the parts list Vcamtech Co., Ltd 11 VISI Mould - Creating Mould Tool Documentation Configuring the parts list Now we have arranged the parts into logical families it is now time to start configuring how we want the parts list to appear, that is what fields we want displayed in the parts table To this, follow the next example: Click on the Settings icon Click on the Parts List position tab at the top of the interface Now from the parts list position panel uncheck the fields as shown below Here we are basically determining which fields will be present in B.O.M table Once you have set the field types accept the changes as shown We are now at a stage where we can begin to number the items and place them in a table Vcamtech Co., Ltd 12 VISI Mould - Creating Mould Tool Documentation Numbering the Items using table mode Now from the main Assembly Manager toolbar switch to table mode to begin organising the B.O.M layout Click on the Table icon You will now be presented with the table mode interface Note the names of the column headers Position, Quantity etc… The components are ordered in the list according to the family name and position The example below shows the cooling family and its relationship to the table Scroll to the bottom of the list using the scroll bar arrow button At the bottom of the list take note of items 62 – 64 These are not required in the parts list as they represent the actual moulding and some 2D plot view information Vcamtech Co., Ltd 13 VISI Mould - Creating Mould Tool Documentation Lets remove items 62 – 64 from the parts list as follows From the Assembly Manager tree, uncheck the items as shown opposite They will subsequently be removed from the parts list We will begin numbering the parts list focusing on one family at a time Lets begin with the Mould Base family Follow the next example to see how this is done From the Assembly Manager tree, make sure that the Mould Base family is the only one checked in the list Take a look at the parts list, items – 12 represent the Mould Base family and are the only ones displayed Lets assign position numbers and then re-arrange the order of the Mould Base family LMB Click into Item then click RMB and select the option Assign position Assign a Position No.1 to the Bottom Clamping plate You should have a result similar to that shown below for the clamping plate Vcamtech Co., Ltd 14 VISI Mould - Creating Mould Tool Documentation Now repeat the task for all the items in the Mould Base family Please make sure the numbers are assigned as follows: - Click on the Position column header as highlighted below to order the list in numerical order The next family that we will number is the Insert family Using the same method as previously described, number the family as follows: Make sure Inserts is the only family checked The numbering sequence (13-16) is shown below and follows on from the Mould Base family no’s The next family that we will number is the Lifters family, please number the family as follows: The numbering sequence (17-23) is shown below and follows on from the Insert family no’s Vcamtech Co., Ltd 15 VISI Mould - Creating Mould Tool Documentation The next family that we will number is the Sliders family, please number the family as follows: The numbering sequence (24-31) is shown below and follows on from the Insert family no’s Now number the Injection / Ejection family to match the one shown below: - The numbering sequence (32-44) is shown below and follows on from the Sliders family no’s Number the Cooling family as shown below: - The numbering sequence (45-47) is shown below and follows on from the Injection / Ejection family no’s Finally, lets number the Screws family to complete the numbering sequence Please see overleaf Number the Screws family as shown below: - Vcamtech Co., Ltd 16 VISI Mould - Creating Mould Tool Documentation Click x with the LMB on the Dimensions column header to group screw sizes together as shown Now click on the set – reset – table selection icon to select the whole family Click with the RMB anywhere on the table and select the Assign position option as shown Assign the position as 48 and the system will increment the numbering sequence forwards through the empty positions Vcamtech Co., Ltd 17 VISI Mould - Creating Mould Tool Documentation The Screws family is now complete with numbering from 48 -61 With all the numbering now completed for each family, it is time to view the full parts list and put it in “Position Number” order Switch on all the families from the Assembly Manager tree You can now see all of the parts displayed in the list Click with the LMB on the Position header to order them as shown below Vcamtech Co., Ltd 18 VISI Mould - Creating Mould Tool Documentation Add the B.O.M into the Plot View 2D drawing Switch to the Plot View mode as shown below and click onto Page from the plot view pages list Now restart the Assembly Manager with table mode active so that the screen looks like the one shown below Please see overleaf for details of how to put the B.O.M onto the plot view page Vcamtech Co., Ltd 19 VISI Mould -
