1 Customising Bolt & Hole symbols for StruCad evolution

2 Customization of StruCad Bolt & Hole Symbols for Drawings The creation of customized Bolt & Hole symbols for StruCad Drawings can be achieved simply by altering two files. The base drawing sheet and the Bolt/Hole type data file. 1. Open a base drawing sheet to add the hole symbol to e.g. forma3.spf 2. Create your bolt symbol using lines, arcs, fill etc. To represent your custom hole/bolt type, this could be a tapped hole for example. Remember to draw your hole / bolt symbol with a diameter of 1mm. StruCad will then scale the block automatically to create a scaled drawing. Hint: Try inserting an existing block, exploding it and using it as a base for your new symbol. 3. Now save your symbol as a 2D block using the block command. We have called this symbol TAP_HOLE. Select the centre of your symbol as the insertion point for the block. 4. Exit and Save the changes to the forma3 base drawing sheet. Hint: You will need to transfer the block to every drawing sheet. Try opening the other drawing sheets, one by one and using the SPFIN command import the forma3 drawing sheet and move it out into space, this will import the extra block, then delete the drawing you have imported. Now we have created the 2D block we need to create a new bolt or hole type reference to be used in the interactive environment to display the special tapped hole symbol on the drawing. 1. Open the holetype.dat file in the data directory of your model with notepad or any other text editor. If you wish to add a new shop bolt symbol then open the bolttype.dat file instead. Hint: Right click on the model in the Workspace and select Explore Directory to browse the model directory. 2. Create a new line below the last entry, H Cell hole, and fill in the columns as described at the top of the file. The line will read something like this : T Tapped holeee tap_hole tap_hole tap_hole tap_hole O Remember: Do NOT use tabs in this file, only use spaces. Page 2 of 5

3 Using the new hole & bolt symbols 1. Load a joint and create or edit a bolt group. In the menu click the Hole Type(s) option and select your new hole type or Bolt Type if you edited bolttype.dat 2. If you wish to have the tapped hole symbol shown on the member drawing but not the endplate drawing, you can edit the bolts and in the hole type selection box type in the single letter code for the hole type require in each ply. 3. For example type OT for a round hole then a tapped hole or SO for a square hole and then a round hole. 4. The drawing will look something like below, the member is tapped but the end plate has an ordinary round hole. Page 3 of 5

4 Other uses for customised hole and bolt symbols The customisation of hole and bolt symbols and be used to create a wide variety of helpful drawing output. Denoting surface finishes on steels or plates, such as Durbar and unpainted areas. Using customised.spf drawing sheets you can easily create full size DXF/DWG profiles for plates using the full sized templates. The 'Full Sized Templates' produce a 1:1 drawing of plates. Using one of the three tblank.spf drawing borders you can produce a drawing which can quickly and easily be converted to DXF or DWG for use with nesting and plate profiling software. 1. tblank-closed-hole.spf - Produces all holes filled in. 2. tblank-open-hole-no-hairs.spf - Produces a round empty hole. 3. tblank-open-hole-with-hairs.spf - Produces a round empty hole with crosss hairs.
