Free 3D Software – Limited Time Offer!

 

Even though this offer has been Tweeted and posted all over the Internet, I thought I would add a quick post here to make sure our readers know about it. For the month of February Digital Art Zone (DAZ) is offering the following software free of charge – you can pick it up at http://www.daz3d.com/i/3d/free-3d-software-overview:

DAZ Studio 4 Pro 3D Software (Winner of 3D World's 2011 Software Innovation of the Year Award): Retail $429.95
Bryce 7 Pro 3D Landscape Software: Retail $249.95
Hexagon 2.5 3D Modeling Software: Retail $149.95
3D Photoshop Bridge: Retail $199.00

The company also said any downloads of these packages would be eligible for future updates at no charge. "We're excited to make this offer early in the year," said James Thornton, CEO for DAZ. "We wanted to give any digital artist the opportunity to experience DAZ free 3D software for the first time, and a full suite of 3D models and 3D animation software products is available on DAZ3D.com."

Even though 3D is still in its infancy in our industry with it only being used in large, high-profile projects, there will come a day when 3D renderings will be an expected deliverable on all projects. The challenge for those of us working now is similar to the one we faced in transitioning from the drafting table to CAD: how to train and ramp up on a new skill that is not immediately necessary so we are ready when it does become a necessity? One of the roadblocks we face is that few companies or agencies will invest the time or money to develop this skill until there is a paying customer or an expectation by citizens. Which is why this opportunity is so valuable. The software is free; all you have to do is invest your time to learn it. And even if DAZ is not the final product your company/agency ends up using, I've found the 3D skills learned using one product do transfer to the next as well as the familiarity with the general framework.

As for learning the software, there are numerous tutorials available. All you have to do is search through Google or YouTube to find them.

Checking out West Coast Tech Talk

Part of the fun of blogging is the opportunity to connect with others who love what you do. In my case, that's anything public works related! One of the people I recently talked to online was @lahtnesorm. He's a civil engineering technology student on Vancouver Island who blogs about CAD. His site has helpful information about CAD in general, and lately he has been blogging about his experiences in learning Autodesk's Civil 3D. You can check it out here: http://www.wctechtalk.com/category/civil-3d-13-weeks-of-learning/

I like reading his posts about Civil 3D because although I am proficient with Map 3D, I have yet to jump into Civil 3D. So his posts are helping me better understand the commitment and effort required to learn that software. And the articles share the benefits he is finding from using the software.

A Day in the Life of a Civil Engineer – Day 5

Day 5

The main items grabbing my attention today involved the following:

Striping

Today the stripers were in town placing the thermoplastic paint on a few of our newly paved roads. Normally I don't get too involved in the operation because we have a project engineer and technician inspecting and managing the project. But today, we had a resident call because she was concerned that we had planned to stripe a crosswalk at a T-intersection. There had been one leg of a sidewalk connection with a depressed ramp on her side, but no connecting sidewalk on the other side of the road. We've been trying to clean these up and either remove the lone leg or add the other side. In this case we added the receiving ramp. Because the roadway is busy, the engineer had planned on placing a crosswalk at this point. However the resident was worried children would be harmed because the crosswalk might encourage them to cross there rather than further down at the 4-way stop.

Thermoplastic Pavement Markings

I met the resident and her husband at the site along with one of our policemen. Over the years I've found it to be a very valuable experience to work together with the police on traffic-related issues. They bring great insight and ideas. And in the end, they are the ones that have to regulate the traffic. The policeman who met me there is an awesome public safety professional who was able to offer his thoughts from a public safety perspective. He shared that we have crosswalks striped all over town at T-intersections, and the police have had no incidents reported. And I indicated there would be no engineering reason that requires us to stripe or not stripe. After reviewing the situation, we decided that based on the four-way stop being close by, we could skip striping the crosswalk. 

Storm Sewer Project

We regularly receive calls related to stormwater issues throughout the community. Most of the time, they do not meet the criteria required for the city to install additional infrastructure. But occasionally the water nuisance is extensive enough that we decide to construct an improvement. This year, we have plans to install a short segment of storm sewer to alleviate flooding that occurs over multiple properties after even a small amount of rainfall. Our crews will do the work so normally we would not prepare a normal set of plans required for bidding. But because we have some interns who are interested in learning CAD, I decided to set up a drawing for them so they could work on developing the plan for this project. Unfortunately we have a CAD product that based on my experience requires us to spend an enormous amount of time that could be cut significantly if we just changed software. But even though over time the new software would pay for itself in savings from subscription fees, it's that initial purchase price that in this economy is preventing me from changing over. So instead every time we draw something, we spend a lot of time generating the plans. To say it's been frustrating is a total understatement. Anyway, I finally today managed to get the plan set up for them to start. Although I never could get the linestyles to display right. And because I just cannot afford to spend more time with it, I am hoping the interns can figure out what is messed up with that.

Reviewing a Driveway Permit

Normally this would be handled by our building department since they issue driveway replacement permits. But last year we had a company come in–well it was more like a guy with a skidsteer who didn't have a clue what he was doing–and in the process of trying to cut curb completely messed up a newly paved road. Why he waited until we completed the road to cut curb and replace drives is still not evident, but the result was damaged pavement because he didn't properly perform this work. So now we are more cautious about letting anyone cut curb. In this case, the contractor seems to be using a reputable company so I expect they will pick up their permit on Monday after dropping off the necessary certificates of insurance and bond we require to work in the right of way.

School Zones

One of our engineers had noticed that some school zone signs remained in areas where schools had moved out of their buildings. He wondered if we should remove the signs so I had our interns looking into this. Today we checked the city code to determine where the city council had established school zones and discovered there seemed to be some school zones still in existance even though schools are no longer located in those areas. And because we have had so much development in the past several years, there are areas with signed school zones that have not been established through ordinance. So the interns are preparing a report of these areas that can be submitted to administration and perhaps onto the council for consideration.

Some of the miscellaneous tasks that filled the rest of the day included:

  • Meeting with an intern who will start working part time with us later this month. This is an unpaid internship arranged through the high school.
  • Reviewed in the field the site of a proposed development
  • Gave our sign shop the sign design our interns prepared for the school zone area

Geospatial Resources & Outreach

Geospatial Revolution LogoThe rise of mobile devices has allowed everyone to discover what those of us in public works have always known – geospatial technology is cool! Now everyone wants to know where people and things are and how to find them. Games and other applications are being developed based on location-based information. And to meet this increasing interest, Penn State Public Broadcasting has created a media-based outreach initiative. Their mission is "to expand public knowledge about the history, applications, related privacy and legal issues, and the potential future of location-based technologies."

Below is the trailer for the series of episodes produced by Penn State. You can view all the episodes on their site as they are released at: http://geospatialrevolution.psu.edu/

Using Unity3D to Simulate a City

Most of my exploration of virtual worlds for engineering has been in Second Life and OpenSim. However, this year I have been looking more at Unity3D. Engineers are conservative and seem to dismiss virtual worlds like Second Life and OpenSim. Even though these programs are 3D modeling tools, they don't resemble nor do they use the typical CAD tools engineers are used to working with. Because Unity3D works well with these CAD tools and better resembles modeling programs, I suspect it will find greater acceptance by AEC groups.

As an example of what can be done with Unity3D, I show below a crude example of importing DEM files into Unity3D. While the process is fairly easy, I still have some issues with the elevations looking too exaggerated, and there is an area that does not have contours. I also need to figure out how to apply the aerial images to the ground. So I still have a lot of work to do to refine this, but I thought it was pretty cool to be able to import contours and see the flat land transform immediately to reflect the topology of my city. I put some water in the model to indicate the river which helps to highlight the dam and islands. But I have yet to add any buildings, trees, or other features.

Another cool aspect of Unity3D is it can be embedded in a browser. Below is the static representation of what I created showing a view looking north through the river valley. Eventually I can add the capability for someone to travel through this model of my city with an avatar.

Smart Tagging Engineering Plans

The city of Manor, Texas, has been successfully using QR codes for some time to convey information to citizens. And a while ago, I blogged about Microsoft tags – another method of conveying information through the use of a code and mobile reader. The Microsoft Tags have intrigued me because if you have time, you can create a code that can be “hidden” in your logo or another image.

Unfortunately I was so excited about trying out the tags that I didn’t take the time to make a custom one. So I can’t demo how cool that would be, but I can show you an engineering-based use for these smart tags. Below is the cover sheet of the most recent set of engineering plans I prepared for a small sewer job we are constructing in my city. On the cover we placed two codes. One is displayed near the JULIE or 811 One-Call logo – by running the reader on your mobile and focusing it on this tag, your mobile is activated to call for a utility locate. Before actually calling, the number is displayed, and you are asked if you want to call.

Dunstan Storm Sewer Cover Sheet

If someone runs the reader on their mobile and focuses on the other tag, the mobile device is routed to the IDOT Website page displaying the State of Illinois Standard Specifications for Road and Bridge Construction. These are just two easy demonstrations of how these codes can be used in engineering and construction. I am sure with time, more ideas will arise. Feel free to comment below with your own ideas.
