Five stars means money

This is a favor I’m doing for this company, give them five stars. In truth it would be 3.5 instead of a 5. Why? The usability of the program is still a bit clunky. I must say however there is a massive potential waiting to be unleashed and if handled properly will give the established cad company a good run for their money. Speaking from an architectural point of view drawing objects like walls needs to be more streamlined with much less steps. What would be a big plus is if you could easily assign a dimension as you draw. Another great feature if they could get it to work would be to define an object and give the user the ability to stamp the object at will on the drawing. There is something presently, but it is a bit cumbersome to get to.

On a whole this program is really not bad, I like it a lot and would encourage design aspirants to check it out for themselves. And by the way asking someone for a five star rating is unsavory and a bit distasteful in my book. Your rating should be organically derived on the basis of merit. Ok so maybe I could honestly give them a 4 instead of a 3.5. Apart from the versatility of the product the price / value ratio is extraordinary high.

Go ahead and give them a shot. I’m already convinced.

I'm beta testing the new Morpholio Trace

Im not a pro at it by any means but I gave it a five. It's a little complicated at first, in comparison to some others and I really don't recommend it for the iPhone because it is really a professional app that any designer could benefit from. There is a learning curve. There are more simple apps that are probably better for beginners. I give it five stars because it is great in the fact it is so clean in its ui and for the short time Ive been using it, I believe it is perfect for someone to hold their best work. I think it would be a wonderful add for someone that is a professional designer of any kind. It's has to be a little complicated in order for it to have the features that it is packed with. I think once I learn more, and can intuitively know all of the tools and changing them when I need to, I will pay for it with my design projects. So if you know Morpholio well, and have the app mastered, you will be just as happy with the up dated version. You have a lot to look forward to. I'm going to play more with this app. One thing I wish I knew how to send my stencils to creative cloud, or to render a Psd file. It probably is able to be done but I am a novice in that department. Such a beautiful app

Invaluable, simple but robust tool with support from real people

I own a design-build firm, so my team and I spend time both conceptualizing/developing designs as well as redlining plans. This app so quickly integrated itself as an essential tool for us. Marking up plans is easy, though we did have issues at first with the legibility of our markup upon export but just had to learn a few tricks. Equally as important, sketching over massing or just doodling is as simple or complex/refined as you want it to be. One of the most impressive things though is the customer support. I recently had a function I couldn’t get to work so I reached out. To my surprise a member of the team emailed me back shortly, conversed with me about the tool that had been removed, asked my opinion about reinstating it, and later even followed up just to let me know that an update was coming out that would restore what I was looking for. It was quite refreshing to talk to a member of the team who cared about the outcome instead of simply navigating some automated system of troubleshooting. Five stars guys, keep it up!
