Having worked with the software now for over a year, here are some of the software’s strengths and weaknesses:Strengths:The interface for creating your geometry is great. We haven’t found very many limitations. You can create individual openings or curtain walls with corners or segmented walls. You can import your own geometry also and use that as the basis of the wall system.

The people at SoftTech in Florida are great. Very knowledgeable and experienced. They are also very available when you have a question. Updates and bug fixes are provided a couple of times per month via an FTP site.

The software is very open. You can create custom macros and code for most things in the software. This is a great feature, but be careful. Once you start trying to code all of your business logic into the software, the software gets complex fast.

SQL back-end (or Oracle). This is the best part. You can write reports and queries directly against the database. We have a custom portal we put in place about 5 years ago. Tying our material data into the portal is much easier since they are both running off the same database.

Weaknesses:

It’s not easy. Even with the years of experience developing our own software, we have been a year in implementation. The documentation on what you should do and how you should set the software up is not good. In addition, the recommendations to create macros and code to solve some of the basic implementation problems are misguided at best. Because it is so open, you can do most things 6 different ways. SoftTech’s view is that every company is different so they leave it up to you how you want to set things up. From my perspective, all the companies I’ve worked for could use the same setup. Before you start your implementation, give me a call.

Missing features. The software has been developed based on the demands of the user base. It doesn’t seem to have some overarching need to do what people need, it seems to be built to do what people want. It can’t do shop drawings yet. It can’t do fabrication tickets yet. You can’t have multiple vendors for your dies (if you push your own extrusions, you need this). It appears to have started as an estimating tool and recently made the transition to operations. The good news is that we have been able to create custom applications to address these needs. I’m not sure every user wants to write thousands of lines of code to do what we are doing.

Overall, I really like this software. I think we’ve found some ways to simplify the implementation and hopefully make this a smoother process for future companies trying to use the software. I’ve had conversations with several companies that are really struggling with getting this implemented. If you are using V6 now, please drop me a line. I’d love to see how things are going for you and share some of the things we have found.

So we started doing some research on software.  When we were in Italy, we looked at the software that Emmegi had created.  We also had a demo of the Logical software.  We met with the folks from Engineering Intent (now owned by Autodesk).  All of them seemed interesting, but didn’t really meet our needs for various reasons.  Finally, Chip Steel from Emmegi introduced me to SoftTech.

SoftTech is a company out of New Zealand.  They make a product called V6.  Essentially, it allows you to create 3d elevations of your windows and curtainwalls and automatically creates the Bill of Materials information.

SoftTech America is out of Florida.  There are about 6 guys working in the states.  Really great people and very qualified.  SoftTech has a development agreement with Kawneer and I think Kawneer has pumped over a million dollars into the software to get it to do what they need.

You start by creating a library of your extrusions and accessories (screws, gaskets, setting blocks, etc…).  You then use these to create what they call assemblies.  The assembly contains the parts that create each detail along with other information like how the parts intersect with other parts and any machining required.

You then create a framing system with the assemblies and finally create your elevations using the framing system.

Our first attempt at simplifying our engineering efforts was to create a custom takeoff program.  We were already creating our own shop drawings, what if we could use the geometric data from Autocad to drive our material takeoffs and fabrication tickets?

We started with an article out of Cadence magazine that showed how you could attach xdata to entities inside Autocad to create BOM information.  We created an Access database that could hold the information and using the Open Design Alliance libraries, we were able to extract the xdata from the Autocad drawings and create a table of information inside Access.

The tag lines inside Autocad were system agnostic, allowing you to apply different systems to each elevation or change the system information without editing the data inside Autocad.  Routines were created to understand where and how each part would intersect other parts so shear block clips and notching could be automatically applied.  Once the data was inside Access, we could create custom reports or write code to fill out our existing material forms in Excel.  The Excel forms were then customized to be able to feed directly into our accounting system so we could eliminate almost all of the data entry duplications.

The tag lines would represent a part (lets say a horizontal).  One line would have a tag called “Horizontal” and would know what elevation it belonged to.  In the database, you could assign your horizontal body, body stop, face stop and shear block clips to that tag line.  You could then create adjustments to the line length.  maybe your face stop needs to stop 1/16″ short or the shear block clips need to be a fixed length.  This data could be arranged into systems and then applied to any elevation.  Finish colors could be assigned at the system or elevation level.  Overrides could be created inside Autocad for any individual part that needed to be adjusted.  Vertical mullions in an elevation would look for horizontal intersections and automatically assign machinings at those locations.

We have been using this system for about 6 years now and have tied the data output to our machines and can create text files to feed the Emmegi software and also some of the other machines in our shop.  We have increased accuracy and by creating a very specific method for takeoffs and fabrication tickets we have been able to hire entry level people and make them successful within 2 to 3 months.

But it still isn’t easy.  It still requires database and Autocad skills.  We have had limited success getting sales to use the program because of this.  When you get a multi-million dollar project with 6 custom systems, it still takes 3 weeks to create and check the takeoffs and another 6 weeks to create and check the fabrication tickets.  That is only one person which makes if really cost effective, but because we are using Access, we can not have more than one person working on one project and that also is a limitation that hampers our ability to get things done faster.

On the plus side, the shop gets really consistent tickets and paperwork no matter who does the work.  The purchasing department and project management departments have very little data entry to do because most of our data is digital (shop work orders, purchase orders, etc…)
