Create a new Assembly document and rename it to Staircase.

Background document

When it comes to working with several people on a big project, or if a project has to be divided into several functional sub-sets, it is sometimes difficult to share work efficiently.

The concept of background document can help with this problem.

Each designer in charge of a part of the project, or each functional sub-set, will then be able to put this document as the background of the sub-assembly he is working on: he will rely on the background document’s building elements in an associative way.

When a change is made to the background document (for example: modification of the opening, modification of the landing dimensions…), the assemblies related to that background document will be updated when loading the final assembly.

Create a background document via File > Background Document and select the Landing document from the list.

The background document appears in transparency in the Staircase document.

Close the Landing document.

Create a new sketch on the plane of the front face of the environment.

Missler Software 51

Calculation of the number of steps

- Height of climb = 2500mm - Theoretical height of steps = 178mm - Number of steps = 2500/178 i.e. 14.0449 rounded to 14 - Calculation of the height of climb = 2500/14 i.e. 178.57mm

Create a new sketch on the same plane as sketch 1. The line corresponding to the step is in construction and not internal to the sketch.

Validate the sketch.

Full staircase

Create a new Assembly document, and then assemble the landing.

Note: The landing is fixed by default because it is the first assembled document.

Then assemble the staircase.

Note: Since the Staircase document is already open, you can use the Inclusion function by checking the Inclusion at origin option.

Position the staircase using the appropriate constraints.

Intermediate final result:

Free exercise

Note: Use the background document to design the posts and guard-rail of the landing.

Exercise 7: Metalworking - Design of a sliding gate TopSolid’Design Advanced Sheet Metal

Exercise 7: Metalworking - Design of a sliding gate

Concepts addressed:

- In-place design - Sketch in the assembly - Using extruded bars - Component assembly - Operation in the assembly: Partial trim by profile - Creation of representations

Create a new folder named Exercise 7 - Sliding gate.

Characteristics of the sliding gate:

- The structure is made up of hollow rectangle sections of 80 x 40 x 2. - Bars are made up of hollow square sections of 40 x 2. - The minimum distance between bars is 110mm.

Create a new Assembly document and rename it to Sliding gate. Next draw the following sketch on the XZ plane.

Add hollow rectangle sections NF A 49-646 of 80 x 40 x 2.

Section trims

Create the main trims to adjust the upper and lower crossbars/vertical sections.

Bars

- The distance along which bars will be placed is 4000 - (2*80-40) i.e. 3880mm. - The minimum distance between bars is 110 + 40 (square tubes of 40 x 2) i.e. 150mm. - Calculation of the number of bars: 3880/150 i.e. 25.86 rounded to 26. - Real step = 3880/26 i.e. 149.23mm at the axis which gives 109.23 from face to face of the tubes of 40.

Create a new sketch on the same plane as sketch 1.

Create a vertical line and add the dimension in relation to the vertical segment of sketch 1. This dimension is equal to (80 -20) + 149.23.

Note: The dimensioning is done in relation to the axis; this will help to prevent any invalidities when changing the sections of the vertical tubes.

Exercise 7: Metalworking - Design of a sliding gate TopSolid’Design Advanced Sheet Metal

64 Missler Software

Add a hollow square section ISO 4019 of 40 x 3.

Repeat this section in linear mode along the direction of the bars (X axis) by specifying a spacing distance of 149.23mm and a total count of 25 (26 - 1).

Result:

Modification of a tube section

Note: For rigidity reasons, the section for the support tube of the wheels is larger.

Edit the bottom rectangular tube and modify the section to 100 x 50 x 2.

Create a new sketch on the support face of the wheels, at the bottom of the 100 x 50 tube, at 500mm from the closing side and at 1000mm from the guiding side.
