3.0 Drawing Procedure

3.1 General

This section describes the procedure used to produce drawings for Stone companies.

Once a project is confirmed with THD by Stone companies, THD will assign a Project Architect (PA). The PA will then create the necessary folder systems and CAD templates for the project. The PA will also be in contact with the client to understand the project brief.

3.1.01 Drawing Template

Drawing templates for Stone Drawing are already preset in THD drive. The preset file includes dimensions, layers and title blocks.

3.1.02 Layers

Most standard layers are preset in the drawing template. For custom layering please refer to 1.7

3.1.03 Drawing Graphics

Please refer to 2.1

3.1.04 Text

Text style in title block is preset in the template. This ensures uniformity throughout all the drawings.

All general text shall be as a minimum 2mm high times the scale of the drawing, uppercase, 0.8 width and Arial font. General text includes; annotation, section tags and dimensions.

Room details e.g. name and area should be 3mm high times the scale of the drawing with 0.9 width, uppercase and Arial font. Text for gird lines should follow the same properties.

MTEXT should be used for all general text.

DTEXT should be used for stone numbering only.

3.1.05 Dimensions

All dimensions style are preset in the template for standard scale i.e. 1:1, 1:5, 1:10, 1:20, 1:50, 1:100, 1:500. For custom dimension style, the PA must be informed.

3.1.06 Round Off

All dimensions and measurements should be round off to a nearest one decimal place i.e. 154.856mm = 154.9mm

3.1.07 External Reference File (Xref)

An Xref is an ‘external reference’ to another AutoCAD drawing file. Any changes done to the main drawing file will be reflected to other linked drawing files. It also allows multiple architects to work on smaller parts i.e. rooms of the main file.

3.1.08 Origin Point

The drawing template has a preset origin point with its own layer properties. The origin point is at coordinates 0,0,0. This origin should be used as reference point for copying and pasting. DO NOT edit, move, alter, unlock or explode the origin point.

3.1.09 Stone Profile

Drawing of Stone profile should be done with closed polyline. Appropriate layers and hatch style should be followed. Please refer to 2.0.

3.1.10 Title Block

Title block are preset in the drawing template. Custom title block should be done by PA. In certain cases, the client provides us with their own Title block.

3.1.11 Plotting pen style

Standard plotting pen style for stone drawings can be found in THD drive. For custom pen style, PA should be informed. In certain cases, the client provides the plotting pen style.

3.1.12 User Coordinate System (UCS)

The world UCS should always be in line with True North of the Project. Any other UCS created should be as per the elevations of the project.

3.2 Master Drawing Procedure

PA will create the Master Drawing file in .DWG or get it from the client. PA will select a “special” point in the Master drawing to be the origin point. The Master drawing “special” point should then align with drawing template origin point.

The Master Drawing should be placed in its appropriate folder. Any changes needed to be done to the main file should only be done by the PA. The PA will then highlight the changes in revision cloud so files that is linked shows the changes and the architect working on that particular changed area is notified.

The Master Drawing will be used as the reference file and all blocking out plans and area calculation drawing will xref from it

3.2.01 Layer Filter Group

Layering style should follow 1.6. In “Layer Properties Manager” create a new Group filter for the drawing with the name “Drawing”. All layers for (20) should be placed under that filter.

3.3 Area Calculation Drawing

In cases where stone contractors need to bid for project or need to quote an estimate price to a client, then Area calculation Drawing will be done by the PA.

Information Needed:

–          Architect’s Drawings

–          Stone Schedule

If it is too early for stone contractors to produce stone schedule for the project, we would at least need the following information below to start the initial drawings:

–          Location of stones used

–          Type of stones used (optional)

–          Dimensions/shapes of stones (optional)

–          Movement/expansion joints dimensions (optional)

Note: THD can also provide 3D services needed for presentation or bidding.

3.4 Shop Drawings

Once the Master Drawing is ready to be used for stone works, isolation of rooms for shop drawing starts.

3.4.1 Survey Drawing

A survey drawing is needed in this stage to confirm that the architect drawings match the existing site. If the client is unable to provide Survey drawing, it is the decision of the client to give a go ahead to the shop drawings

3.4.2 (20) Blocking out Plan

Blocking out plan drawing is the process of isolating individual room plan from the whole Project.

The Master Drawing will be xrefed to the (20) series drawing.  The Xrefed drawing’s origin point should be placed at 0,0,0 with UCS set to World and rotation angle to “0”.  The room selected from (20) series should be “XClipped”. This whole process is done by the PA.

Xref drawing should be under the layer “A-Z000-G-xref”

Greying Out

Any layers not necessary for the project should be hidden. All necessary layers from the Xref drawing should be in colour Grey; index 8. This can only be done by changing the filed in “Layer Properties Manager”.

Colour Representation

All stone should be colour coded to represent different types of stones used. Refer to 2.3.

3.5 (DE) series

The detail drawing are drawn once the (20) series are approved by the client. In certain cases the two series are done in parallel. Most of the information is usually provided by the client. But certain information needs the input of stone contractor i.e. stone joints, movement joints, connecting joints etc.

Any changes in the (DE) that affects the (20) or (22) series should be informed to PA who will then change it in Master Drawing.

3.6 (CS) Cutting Sheet

The drawing template for Cutting sheet can be found in THD drive.

The Xref drawing for cutting sheet will be (22) Series drawing. The placement of the Xrefed drawing should be placed at coordinates 0,0,0. Change all Xref layers to Grey; colour index 8. Xref drawings should be under the layer “A-Z000-G-xref”. Once Xrefed and XClipped are done, importing of stone profiles is next.

3.6.1 Importing Stones profiles

Copy all stone profiles drawing (do not copy the hatches) from (22) Series and place it over the drawing in Cutting sheet in coordinates 0,0,0. Change the colour of the stone layers to Red, colour index 1. This is done so that there is no need to re draw all stone profiles again. The colour is changed to red so that it stands out in the drawing as all other elements are in grey.

3.6.2 Stone Numbering

All stone numbering should be done in DTEXT. It should also be under its own layer separted by stone type. There is no standard method of numbering but it should be a mixture of letter and number i.e. F01.

3.6.3 Stone Layout Area

There is an area to place stones for the purpose of dimensioning. This area is preset in the drawing template.

Copy all stone profiles (in red) and stone numbers for the Drawing Area and place it in the Stone Layout Area.

3.6.4 Dimensiong for Cutting Tickets

The standard scale used for Cutting tickets is 1:20 but the client can request to change this. The dimension scale should be 2mm high times the scale of the drawing.

Gross Dimensions

A Gross Dimensions is needed by Stone companies so that they can cut out a block from which the shape of the stone will be cut out.

A “Gross stone” outline in dashed with colour Grey will be created and put under layer; “Gross Stone_StoneType”

3.6.5 Net Dimensions

THD usually do not include net dimensions as it is not necessary for Cutting Machine. However on request, it can be done.

3.6.6 Cutting Tickets

The Cutting ticket template is already preset in the drawing template. The size of the paper is A3. It includes an automation calculation.

 

Note that if the client decides to use their own cutting ticket template, the automation calculation may not work.

3.6.7 Automatic Calculation.

To avoid humar errors in data input in the cutting sheets, THD tries as much as possible to minimze human imput.

Below you will see the cutting sheet template.

  1. Dear Sirs,

    I would like to know how you operate and charge your drawings. Please send me some samples of your work. Do you take small jobs as well? like one room walls floors for example?

    Regards
    Ziad Farah.
