I like that this program has many different sections where one can add as much detail into each section about what they are wanting in their model so there isn't always confusion for me between adding walls/roofs versus floors etc...and then creating my project file within QTVAAR once completed! Sometimes some steps seem easier with another programme such models but having both will definitely assist because sometimes if something makes sense only using qtvaraar doesn’t do exactly right which means manually drawing out every line again could be tedious. For most cases everything seems ok however please note how far away from your camera view should all points appear? Also not everyone finds building modelling intuitive especially those who haven;'ts used other construction programmes previously - even though learning curve may feel longer than expected at first use does give benefit eventually I like that modelur can be used as a 3d building modeler as well as a 2d drawing modeler. The ability to use the same file in both programs is great. Modelur is easy to learn and use. There are many features to choose from and everything is organized so that you don't have to look for them. I do not dislike anything about modelur. There are some minor things but nothing major. I highly recommend using modelur. I am able to produce my own plans with modelur instead of paying someone else.
