Tutorial¶
This exercise illustrates how to create screw-nut shape from scratch.
Step 1. Sketch¶
At this step we will create a regular hexagon.
Create a New Part via Main Menu Part - > New part
Start Sketch creation via Main Menu Sketch - > Sketch
Set Size of the view parameter equal to 250 in the Sketch dialog
Select XOY plane in the view
Click Set plane view button in the Sketch property panel
Start Line creation via Main Menu Sketch - > Line
Pick 3 points in the view one by one and select the first one at the end to get a triangle
Hide trihedron via Show/Hide trihedron button in viewer toolbar
Select Origin object from Part set / Constructions folder in the object browser
Click on the eye icon on the left of the origin item to show it in the view
Select both origin and the bottom vertex of the triangle in the view (use Shift key for multi-selection)
Create Coincident constraint via Coincident button in Sketch toolbar
Show trihedron
Select both OY axis and the upper side of the triangle in the view
Create Perpendicular constraint via Perpendicular button in Sketch toolbar
Select the left and the upper side of the triangle
Create Equal constraint via Equal button in Sketch toolbar
Make the upper and the right sides equal length in the same way
Select the left side of the triangle
Check Auxiliary check box in the property panel and click Apply button
Make the right side auxiliary in the same way
Start creation of Angular copy feature via Angular copy button in Sketch toolbar
Select the upper side of the triangle for Segments parameter in the property panel
Select origin in the view as a center of rotation
Set Total number of objects equal to 6
Click Apply button
Select the upper side of the hexagon
Start creation of Length constraint via Length button in Sketch toolbar
Set length expression equal to “a=115.4” and press Enter
Click Apply button in the Sketch property panel to finish the sketch creation
Check item corresponding to the created parameter a under Part_1 / Parameters node
Step 2. Polyline¶
Start Parameter creation via Main Menu Part - > Parameter
Set parameter name = “h”, set parameter expression = “90”, set comment = “nut height”
Click Apply button to finish parameter creation
Start Point creation via Main Menu Construction - > Point
Set x = 50, y = 0, z = 0
Click Apply button to finish point creation
Create points (80, 0, 0), (112, 0, 13), (112, 0, 48), (80, 0, 63), (80, 0, h), (50, 0, h) in the same way
Select the created points in the object browser under Part_1 / Constructions node
Click right mouse button and select Color… item in the popup menu
Select blue color and click OK button
Start Polyline creation via Main Menu Build - > Polyline
Select all the 7 points (use Shift key for multi-selection)
Check Closed check box
Click Apply button in the property panel
Step 3. Face¶
Start Face creation via Main Menu Build - > Face
Select Polyline_1_1 in the object browser under Part_1 / Results node
Click Apply button in the property panel
Step 4. Revolution¶
Start Revolution creation via Main Menu Features - > Revolution
Select the face created at step 3 in the view
Click on axis input field in the property panel and select OZ axis in the view
Click Apply button in the property panel
Step 5. Extrusion¶
Start Extrusion creation via Main Menu Features - > Extrusion
Select the hexagon created at step 1
Click on axis input field in the property panel and select OZ axis in the view
Check By bounding planes and offsets option
Select the bottom face of the revolution shape as From plane
Select the top face of the revolution shape as To plane
Click Apply button in the property panel
Step 6. Common¶
Start Common creation via Main Menu Features - > Common
Select the extrusion and the revolution in the object browser under Part_1 / Results node (use Shift key for multi-selection)
Click Apply button in the property panel
Step 7. Fillet¶
Start Fillet creation via Main Menu Features - > Fillet
Select the edge
Select Radius parameter equal to 10
Click Apply button in the property panel
Step 8. Box¶
Click right mouse button in the view and select Hide all item in the popup menu to clear the view
Start Box creation via Main Menu Primitives - > Box
Set DX = 10, DY = 120, DZ = 20
Click Apply button in the property panel
Step 9. Translation¶
Start Translation creation via Main Menu Part - > Translation
Check By X, Y and Z dimensions option on the top of the property panel
Select the box in the view
Set DX = -10, DY = 20, DZ = 70
Click Apply button in the property panel
Step 10. Angular Copy¶
Start Angular Copy creation via Main Menu Part - > Angular Copy
Select the box in the view
Click on axis input field in the property panel and select OZ axis in the view
Set Nb copies parameter equal to 6
Click Apply button in the property panel
Step 11. Cut¶
Select Fillet_1_1 item in the object browser under Part_1 / Results node
Click on the eye icon on the left of the result item to show it in the view
Start Cut creation via Main Menu Features - > Cut
Select the fillet object in the view as a main object
Select the angular copy object in the object browser as a tool object
Click Apply button in the property panel
Select the created Cut_1_1 item in the object browser under Part_1 / Results node
Click right mouse button and select Color… item in the popup menu
Set (R: 255, G: 214, B: 0) color and click OK button
