### 5/5 — Works great with sim lab composer.

*2020-04-25*

Read all these reviews of people thinking this is just some free to use software and don’t understand that it requires sim lab composer.  Works great and as intended otherwise.

### 1/5 — I don’t know what it’s for

*2019-01-08, version 4.3*

How do you make a new building? It glitches and takes forever to load. Nothing works. Don’t get it

### 1/5 — Cannot open files

*2017-12-31*

I downloaded this app to view my files but it just does not open files. Deleted three minutes later

### 1/5 — Unbelievablely bad

*2017-12-24, version 4.3*

*2014-07-30, version 3.06*

Waste of time

### 1/5 — Terrible

*2013-02-16, version 2.2.1*

This is one of the worst apps I have ever downloaded it is absolutely BAD

### 3/5 — Downloaded model but not available

*2012-02-11*

Looks promising but all that's viewable is the demo models. I downloaded Dropbox Sketchup model several times - asked to replace file so I know it's there but they don't show in model list. I found the user interface very different from standards and not real easy to understand exactly what is meant by various controls.

### 1/5 — ;(

On my iPod it crashes like 3secs after I open it

### 1/5 — fails to run

*2012-01-07*
