IronCAD

It doesn't come with all the CAD format importers you need. If you share files with other more expensive software users, you may have to purchase additional importers. If you work alone like me, you rarely need that but occasionally I'll have a file I can't import and have to request an alternate format that I can. IronCAD can import a lot of formats by default, but a few exotic ones are not included.

Very little cons, we work with a lot of large assemblies and IronCAD often switches into large assembly mode automatically. This had to be turned off to allow for a deeper level of editing but can be useful in certain circumstances.

It was quite expensive, considering the lack of maturity in the product. I started a bug list but then stopped because there were so many. The parametric architecture is fractured and disjointed. Dimensioning in the 2D drawing module is too erratic to be usable. Dimensions in the 3D module hide by default and it's hit-or-miss as to which object to activate to show a placed dimension. Not being able to export to sldasm or sldprt with the translator was an unexpected and stunning deficiency considering the price I paid for the Translator. Having the file format change right after I purchased the software and NOT BE BACKWARD-COMPATIBLE was almost a death blow to my continuation as an IronCAD user since it prevents me from adding seats without complications or extra expense of upgrading. It was a bit galling to see the heavily-discounted price offers right after I paid a higher price, and I now see that you tricked your new users into buying a soon-to-be-obsolete version. Being barred from having an account in the forum simply because I chose to purchase a perpetual license and no maintenance plan was quite a slap in the face. The single-project-file structure isn't particularly valuable (S/W has the Pack-and-Go feature). It actually complicates CAD library management. The Help file is terrible. Most entries simply describe the labels that are already readily-visible on a given dialogue box. Example: "LOAD Button: Click this button to load <the file, object, etc.>."

While there are many video tutorials available to help anyone learn and use IronCAD, the lack of a comprehensive, current User Manual is a negative. I recognize that such a manual would be a large undertaking, but I still think it is needed.

Simply the lack of proactive marketing by the developers who were very focused on the software and its abilities rather than getting involved in its awareness in the market. If they had been more marketing focused in the early years then they would have had the development funds earlier for product enhancements.
