ALSIM vs. Ansys SpaceClaim vs. DraftSight

I will highly recommend Ansys SpaceClaim, or in fact any Ansys to my colleague because of its wide spread acceptability around the globe and around the different industries. Thus, the results provided by Ansys simulation tools, given the proper boundary conditions are properly simulated, are highly reliable. Also, learning to utilize Ansys tools in the engineering design activities also helps in career advancements.

Large area (500m²+) analysis and assessment

From product design, including production drawings to lay out of large (10m x 1m footprint) layouts DraftSight is a cost effective solution providing all appropriate interfaces for BIM.

The level of detail during rendering (while it can be slow) is good for visualization and for use in installation and training materials

• It efficiently divide/split the surface into multiple fragments as per the user's requirements which helps in easy application of loads and boundary conditions.
• It helps in reducing the model complexity with it's efficient defeaturing options in order to reduce the model complexity.
• It also helps in making quick model changes as per the simulation results in order to improve the design and thus helps in quick FEA of the improvised design.

• You can easily bring in a dwg format drawing into the programme and it will display the information just as well as AutoCAD.
• The programme supports shortcut features or one-click buttons for the most commonly used operations.
• Script files can be used which is a bonus.

• With time, Ansys SpaceClaim has evolved so much in its functionality and Ansys has added so many useful and complex features into it, but most of the team member are not aware about those features.
• For the newly added features and improvement in legacy features, Ansys can try adding training videos to better aware the engineers about their evolving features.
• Apart from that, I don't find anything disadvantageous about SpaceClaim.

Incentivized

• The text search and replace is very crude and barely works. Needs a major revamping.
• The layout tabs are very clunky and hard to use. Needs to be fixed.
• DraftSight will fix a problem in one version, mess it up in another version, then fix it again later on. And so forth, and so forth, and so forth. Very poor software update control.

It has given us, a small startup, the ability to compete effectively with far larger competitors by evening the playing field at a low cost.

As a Mechanical Design Engineer working in and designing heavy structures for battery packs and chargers, I use Ansys SpaceClaim, day in and day out regularly as whenever the design team forwards the CAD model to FEA team, FEA team optimizes the model in SpaceClaim only, and to do so, design team also helps them in Ansys SpaceClaim

Easy if you know how to use CAD software. But is not very difficult to learn using DraftSight if this is your first CAD software. As soon as you get in to it the work flow will save you a lot of time and its simple interface is very nice.

Other than a bug created by a VAR tech support that didn't get resolved until I installed the next version, DraftSight has worked fine.

In general it's very quick to load drawings...now it depends a lot on the file we're opening or working on.

Technical support seems to be overseas with broken English and difficulty to read English. I asked for a trial license to try the fix but it was declined. Ask pratiksha.dahotre and gayatri.keskar for details. In summary, they released a broken version, I helped to fix by providing feedback and error logs. They claimed it is fixed but I can't test it.

Based on some knowledge of AutoCad, using Draftsight took a short time before I felt comfortable using it.

Take time to get used to where commands are and how the interface can be customized to suit your needs and work style. The keyboard commands are very helpful and can make work more efficient if time is taken to learn them.

For the FEA analysis, PTC Creo, which is a CAD modelling software has inbuilt FEA simulation tool called as Creo Simulate which we generally use a very quick FEA on smaller parts. But when the geometry is very complex and we need to simplify it before the simulation, then we use Ansys SpaceClaim to simplify the model and then use Ansys Mechanical for structural simulation.

While SketchUp is free, DraftSights cost is minimal and its abilities are much greater. It is so much easier to layout and modifies a system design. Since DraftSight is compatible with all versions of CAD, it makes it easy to collaborate with customers on their specific system design. We spend less time and see greater sales on our projects.

It's a typical contract for cad software. It was inexpensive at the time I started. But now the more useful features are on the more premium (priced) version.

As a startup, we really appreciate scalable software or tools, and because we use it for diverse types of projects, flexibility is key.

Quite responsive when I have an issue, and with little to no delay in responding. They are professional and know the software so have been able to solve all of the issues that I have had with both using the software and also with making revisions as required. Non-technical issues like invoices have also been resolved quickly.

• Ansys SpaceClaim helps in easy modelling different types of design and different iterations of design which in turns helps in designing a cost effective products thereby saving a lot of material and production cost.
• Because of the easiness in modelling, changing and modifying the design and then running the simulation over it, the design team is able to test and every concept, which I turn helps in producing an efficient and cost effective design.

• Draftsight has been very cost effective, it was free a few years ago then £79 a year, which it still is if you have the standard version. Now the minium level is Profession edition at £159+ VAT per year. Which is still very good value for money, just more that what we currently pay with the standard licences we have.
