I am having difficulties in finding a way to use the input path and set is as the output path for a simple Copy Features tool. I use the substitution by the workspace but it outputs the results into the default ArcGIS folder.
I am not sure how to set the workspace to hold the path of the input feature class. As the input feature class is a parameter, I cannot use a hardcoded path. Please see below:
Indeed, marking intermediate parameters as Managed can cause issues. Below is an example of using the Raster Calculator and then Raster to Polygon. When using in_memory the model fails; when marking the intermediate outputs as Managed, the in_memory - even though exists in the output path - is ignored and the data is written to %temp%, as the Scratch folder.
According to the in-memory workspace documentation, "Tables, feature classes, and rasters can be written to the in-memory workspace" and therefore it is not clear why it fails. This is not the first time that a 'funny' behavior of in_memory is reported by users, in this 4-part article the author reports of what seems to be in_memory data written to the disk rather than to the RAM (Python, ArcGIS 10.2.2). I therefore find that using Managed is to 'play it safe' in a way, saves the trouble of testing how each model performs.
With that in mind, I would like to mention two additional aspects to consider. Firstly, if the Model is to be published to ArcGIS Server, administrators may prefer the use of memory over storage and vice versa depending on the available resources and architecture; Secondly, according to the ArcGIS Pro documentation, Managed and Intermediate "The Intermediate and Managed options have been removed in ArcGIS Pro ModelBuilder". I gave it a go and tried both options in ArcGIS Pro 1.0. Surprisingly (or not), the results are exactly the same as running the Model from ArcCatalog.
The above is for 10.3.1 and not 10.1 (the version in question). However, the key relevant documentation has not changed since. I used Win7 and Win 2008 R2.
Making intermediate data managed data - 10.1 | 10.3.1/latest
Using in-memory workspace - 10.1 | 10.3.1/latest
In the Calculate Field code block you need to enclose your substitution in double quotes so the return line should be
return "%Class 1%"
repeat for the others.

In the first example, you can parse the path and call
%Value%. In the second example (which may not apply in your case), you can write intermediate files to in_memory workspace--thus, eliminating the need for parsing the path and possibly eliminating the need for the Copy Features tool.
