2D Detailed Drawing
Parametric 2D CAD Detailing using T-FLEX; for a brief
- Designs are saved to ".grb" files; each
file can save multiple "Window" spaces
linked to a single model.
- Uses a
simultaneous solver; 3D shapes are linked to
"parent" sketches, which in turn can be
spreadsheet files, etc.
- Some concepts (Sketches, File Windows, Model Tree,
Construction Lines, etc) may seem similar to
Creo CAD Software
- Most commands can be applied to create/modify
either 3D closed solid or open surface
- Most commands have Options (see Automenu)
and Parameters (See Properties Window)
- Often there is often more than one way to perform most tasks in
- T-FLEX .grb files can be externally referenced
into other .grb files as "fragments" (either in 2D
or 3D - more about this feature in our detailed
drawing and part assembly tutorial pages).
When working with T-FLEX it is important to understand the basic distinction between a detail drawing and a 2D CAD sketch. Sketches are 2D parametric views used to create 3D profiles. Detail drawings are human readable files that contain text, dimensions, targets, company logos and are often used as legal contracts for work. 2D CAD sketches are always 1:1 scale representations that don't care about what sheet size sits in the plotter. Detail drawings, on the other hand, begin with creating a border and views to a scale chosen because it fits to a certain size of paper (i.e. A2 etc)
In order to create our 2D detail drawings we will be using an auxiliary element of T-FLEX CAD system – the drawing view. We will also have a chance to look at some additional views including detail views. This function allows us to collect elements from multiple pages and collect them together on one page, insert an image from another page in various scales, even create a simple assembly from parts contained in the same document.
T-FLEX works on the following principles:
1. T-FLEX Detail Drawings are created in a separate workspace from 3D part modelling.
2. 2D drawings and 3D part are associative (logically linked together). Changes in the 3D model can be automatically updated in the 2D drawing
3. Unlike 3D CAD sketches which are always 1:1 scale representations that don't care about what sheet size sits in the plotter, Detail drawings; on the other hand, begin with creating a border and views to a scale chosen because it’s fit to a certain size of paper (i.e. A2 etc)
4. The two workspaces perform different functions for the same design, like handing someone an actual 3D prototype part and a printed technical drawing to go with it.
5. T-FLEX uses "bottom-up" design technique which requires individual parts to be created before assemblies, simulations and detail drawings (individual 3d parts)
Creating primary views
1. To create a new drawing view to go the tab WINDOW>
New Window. A separate box should appear. Create a 2D view. This should open up a separate but linked window as indicated by the title bars NONAME1:1 and NONAME1:2.
2. While still in window NONAME1:1 select the
2D projection icon from the command toolbar.
3. Select which face you wish to project. You should notice they outline in red and once selected that particular will become green. Simultaneously a pink square will have been created in the window NONAME1:2.
4. Selecting this pink box will generate a blue box. The blue coloured box allows us to move the image while clicking the mouse again will return the box to being pink and anchoring the image.
5. Select finish when the image is in the desired place. A warning may appear but select OK to continue. You should now be able to see your image in the new window.
Select paper size & border to match
1. To change the paper sixe of our drawing view go to Customise > Status. A new window named “Model status” will appear.
2. In the General tab, go to the Paper Size and using the drop down menu for Format select the desired size. Otherwise you may manually enter the width and height of your paper. You may even choose to change the orientation and scale used.
3. We are going to continue with our draw view by adding in the other sides of our 3D model into our draw view. It works in much a similar process to before however you may wish to choose a different scale for your images in order to fit all the different views into the page. These views were generated using a scale of 1:4.
4. Alternatively you may chose from a selection of icons which will automatically produce the desired projections. Once the Projection icon has been selected, the auto menu on the left will appear and allow you to choose from the following icons:
Create standard projection icon, Create set of standard projections icon or Create local section view icon.
From here we can add additional features to our drawing view such as a title, dimensions and a company logo.
While in file NONAME1:2 click on the "Dimension" tool. Select one side of an object in your drawing view. It should highlight red. Now select the corresponding parallel side and you should notice a dimension appear between the two sides with a value of the distance. Select a location for your dimension. Cancel this tool when finished.
Notice what happens when you try to edit these dimensions by double clicking on the dimension values. I’ll change one dimension to 20mm. The following notice should appear.
This states that changes to this dimension will also create changes in the original 3D model and its projections. If will notice that T-Flex automatically updates all changes in real time.
To add text to your drawing views click on the “Text” icon
in the top auto menu. This will bring up a cursor and allow you to select where you wish your text to be placed. The text auto menu on the left hand side should also appear but change once you have selected your site for text.
The “Edit text in separate window” icon opens the Text Editor window to allow you to change aspects of the text including formatting, layout, fonts, style, borders, adding mathematical symbols etc. Once all text has been entered go to the FILE dropdown menu and click “Save and Exit”. If you make a mistake simply close the window and choose not to save changes.
Adding a Title Block
The title block of a drawing, usually locate din the bottom right hand corner, contains all the important information required to identify the drawing and to verify its validity. Such information may include a drawing title, drawing number, drawing scale, contract number, signatures, approval dates etc which are used for identification and filing purposes.
To add a title block to go the drop down menu titled “Title Block”, select Title Block and Insert.
The “Select Title Block” window should appear. Select the appropriate type required and click ok.
The following Parametric window should appear which information can then be manually entered into the corresponding tabs.
Doesn’t appear to be working. Diagnostic message “This title block is intended for inch drawings” continues to appear and title block is not created once all details have been entered. This is regardless of the title block type I choose.
To edit text, click on the “Text” icon
and select the “Execute Edit Text Command” icon
in the side auto menu. This function will allow you to make changes to existing text.
To move text to a new location click once on the text you wish to move. This will change the text to a pink colour and you will notice a transparent copy of the text appear with the cursor. Move this to your new location and click once again to anchor the text. Press cancel once completed.
To edit the wording of the text simply double click the text and retype the new text. Press cancel once completed.
Adding a Company Logo
To insert a company logo, simply copy the image you wish insert, right click the mouse and select paste. Once your image has been pasted you have the option to move whole picture, scale or rotate the image using the icons that appear around the image once it is selected.
