Friday Training Follow Up: AutoCAD – BOMA Polylining

Robert Stephen Consulting, LLC provides free 30-minute Client Training session every Friday at 10:00AM PST!  RSC prides itself in providing learning opportunities for our clients.  We feel that if our clients know the system better, we will able to work better with them to discover and implement the solutions that they need.

Last week Matt Ritzman led our Client Training on AutoCAD Basics: BOMA Polylining. Below is the outline of the training:

Polylines to BOMA Standards

Polylines are derived from lines and arcs. My favorite AutoCAD tools that help to create polylines are the following:
LINE
ARC
OSNAP
Object Snap Tracking – also TRA
PLINE
BPOLY
PEDIT
JOIN

Developing an understanding of the available tools and their quirks allows you to create your polylines much more efficiently.

BOMA Standards

BOMA = Building Office Managers Association
The purpose of BOMA standards is to assign spaces in a way that all owners and lessors can agree on the area that is being used.  BOMA is concerned about relationships between owners and renters.  This means that these standards don’t account for areas within a rented space.  That is to say, BOMA doesn’t care how you polyline a cubicle or a desk.  There are other standards that are less concerned about exact measurements that are worth knowing about:
NBSAP = National Business Space Assignment Policy from the GSA (General Services Administration)
Used by government.  This is concerned with how space is defined on a much more granular level than BOMA.   But less concerned with exact measurements of space.
FICM = Facilities Inventory and Classification Manual
Used by Education.  This is similar to the NBSAP, in that it focuses on Space.

Categories and Types

The area measuring standards allow you to be confident about the space that you occupy.
– It gives you the ability to negotiate with your renters or the landlord according to facts rather than estimations.
– It allows you to report consistently on space categories, types, uses, and standards.

We’d love to have you join us for our next on System Administration, specifically Schema Changes on Friday, January 8th.

Our weekly client trainings are held Fridays from 10:00 AM to 10:30 AM PST.  This is an opportunity to learn more about an area of ARCHIBUS that you may not be familiar with.
We look forward to seeing you there!

AutoCAD Advantages: BPOLY Command

Here is a little tip shared by one of our AutoCAD experts, Matt, at Robert Stephen Consulting, LLC.  Enjoy!

Background

The BPOLY command is useful to create a polyline that bounds existing geometry. It is much like the HATCH command or a paintbucket/flood-fill in a paint program.

General Usage

Often lines around a room are determined as LINEs or XLINEs. BPOLY is then used to create the polyline that fills the Remaining Area without any gaps.

After all the rooms have been PLINE’d, BPOLY is used to create circulation and other remaining spaces.

Cautions

We’ve found a little problem with the BPOLY command.  The BPOLY command may skip vertexes when you use it on

  • A fairly large area
  • Containing small vertex offsets

There are two solutions:

  1. Split large areas into smaller ones (particularly large circulation spaces).
  2. Use special care to be certain that vertices align.

How big is this problem?  This appears to happen with distances on the order of 1/100,000.  It could cause your total area to be off by fractions of a percent overall.

The real problem arises when we have to track down a remaining area in a drawing and run across these little glitches.  It is becomes difficult to tell where the actual problem lies.

  • Polylines should be Concave whenever possible
  • BPOLY is view dependent, the entire area to be filled needs to be viewable on the screen before running the command.

A complicated area, like this:

Should be simplified to something like this:
