bocad3D solutions

bocad3D is a wonderful tool that will create detailed drawings, NC data, MTOs, bolt location lists and custom outputs for different departments on your project.

Many of the features of bocad3D require skills beyond simple drafting, including intimate knowledge of standards, limits of the software and other restrictions.

I.T. Navigate has been supporting bocad3D and programming FFEIN since 1994. We started "simply" on an HP Apollo 715/50 running HP-UX 9.x. bocad-3D was version 17.4xxx at that time, and the Windows version didn't exist yet.

In that time we have come across many requests for macros that assist in the day-to-day detailing process.

If you'd like to incorporate and use these solutions, drop us a line. Contact Colin at colin@itnavigate.com.au.

30 second stair

posted 18 Feb 2013, 20:24 by Colin Manning   [ updated 26 Mar 2013, 06:56 ]

Imagine the process of creating a stair in your project. It involves making treads, handrails, stringers, landings, bolts and much other fine detail. If you're fast, this will take you around 45 minutes. If you've never done it, you'll need to look up the Australian standard and make sure that your efforts comply.

Now imagine, picking the top and bottom point, filling out a dialog box and clicking go. 30 seconds* later your stair is done.

This stair has the following properties:
  • Meets the current Australian standards
  • Custom treads with custom treatments
  • Landings, top, bottom or both
  • Concrete or Steel connections
  • Handrail is optional
  • Custom width and nosing
  • If you have stringers in place, you can use those to place the treads
  • To make your life easier the treads are modeled as one member and are named as per the Webforge naming convention

* Actually we're kidding with the 30 seconds. On a 2.67GHz notebook, it takes less than 10 seconds.

CHS Handrail

Create a CHS Handrail in seconds. For Bocad users in Australia, the PST Handrail has been the standard way for placing Monowills handrail. It does the job well, but there are some issues.

Some history

The original PST Handrail was modeled using square bar for the stanchions, rails and balls, and the balls and baseplates were placed as dummy members.

When PST wrote the original macro, Bocad was running on HP computers running HPUX, with a massive 64-128 MB of memory - Megabytes, not Gigabytes, and running at lightning fast 75MHz - again Mega, not Giga! The limited performance (by todays standards) of these computers required simplification of the model as much as possible, hence using solid square bar (One point for each end - two points in total) in lieu of a CHS (as much as 36 points at each end - 72 points). This provided a considerable reduction in the time to generate or refresh views, and the size of the model database.

Another simplification involves creating dummy balls and dummy baseplates. The dummy baseplates can lead to incorrect bolt location lists, as the bolt list may indicate that the beam is bolting to an unknown member, resulting in wasted time, mistakes and frabricator queries. The model is not complete and not directly manufacturable.

Our Solution

Based on the original PST macro, the modified macro places the stanchion and rails using the profiles documented by Monowills, and creates the stanchions as one member. This allows the selection of the stanchion as a member, not requiring the operator to remember to select the stanchion as a construction group or assembly, and the beam is bolted to the stanchion member, not the stanchion assembly.

We have also modified the dialogue box for PST ==> Handrail ==> General settings to allow for Shop vs Site run handrailing, and merged vs non-merged stanchions.

We have also modified the end closure macro to place either a top, bottom or horizontal end closure, naming it to comply with the current Monowills naming convention - less work when it comes to editing your drawings or lists.

In summary:
  • Use CHS instead of Solid Bar
  • No dummy members
  • Single part stanchion
  • Model represents actual build, rather than approximation
  • Option to select Shop vs Site run handrailing
