Dear Team, I would be thankful to be pushed in the correct direction regarding the following issue:   Goal: Achieving to change wall types from a project into own pre defined wall types, Methodology so far: thanks to the explanation on the blogs and good practice material, a good understanding has been achieved on getting parameter data from Family’s/family/types and family instances. Changing the wall parameters as height etc is understood as well. (bellow two print screens of getting and setting parameters , in this case of a space familly) [caption id=“attachment\_11727” align=“alignleft” width=“300”] ![get_parameters](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/2X/9/9981b5ad20e4646e8880955d416c7a13c9261bf4.png) GET PARAMETER[/caption] [caption id=“attachment\_11726” align=“alignleft” width=“300”] ![set_parameters](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/2X/2/282c539c1bef15f49377f29b8d2360f7bb22b2b0.png) SET PARAMETER[/caption]               when it comes to changing a wall type i seem to be in the mist of knowing how to use the correct nodes. In order to change or set set a wall type i assume i should involve nodes as bellow screen, though i cant find descriptions of how to use these (trial and error approach let me down as well) [caption id=“attachment\_11728” align=“alignleft” width=“300”] ![SET TYPE PARAMETER](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/2X/a/a65a452fcb188c911a68ac6dbca36b100203d86d.png) wall family change nodes[/caption]               I would be grateful if i could have a push in the correct direction. warmest regards Dino   ---

Hello Dino, The clockwork custom node works great, but works strictly for family instances.(furniture, columns, etc.). Walls are system families and you need to proceed a bit differently with them. There is another custom package called “[archi-lab.net](http://archi-lab.net)” which has a node called “Change Family Type” that will work for walls as well. ![2015-02-03_121737](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/2X/7/7a12a303b24aee6b54c53d6d47133640ec0fc5fc.jpg) EDIT: Good catch, Andreas! 🙂 I wasn’t aware you can do that with OOTB Dynamo nodes. ---

Dear Andreas and Dimitar, Thank you so much for taking time and sharing the correct methodology on this matter. You helped out tremendously .   warmest regards, an thrilled and excited learner of Dynamo         ---

Hi team, After implementing the method described above, i seem to overlook something. ![test_wall_types](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/2X/9/905336ec6cc346527957ca806c4f1a230b207890.png)               Am i using the wrong starting node (wall category)? The error refers to the following: ![error](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/2X/5/557fe99c34f04c9d60fbe47e1589e79a9ba8fc1c.png) ---

Dear team, Dimitar’s approach worked, though i had to use the " change family Type" from the Grimshaw package. bellow is the setup that solved it for me (test only). ![working method](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/2X/0/0fc8cc5d8363b6954d44bf054618fc6e884ab7e3.png)               May i ask if it is possible to change the “width " of a wall type , previous trials gave the” parameter is read only" warning. the wall type itself would consist of only one layer. It is will be good to have a general understanding to know if this is restricted or if Dynamo can actually access it and change such “read only” parameters. PS, no spoon feeding is required though a general description would be appreciated 🙂         ---

Dino, here’ s the short answer regarding manipulating the wall width - is it possible? Yes, since the Revit API allows for the editing of a wall type’s compound structure and its layers. And no, becausecurrently there is no node or custom node that does just that. ---

Hi Ritesh,   i do use the 0.7.5 version and the latest packages ( Revit 2014 though) I just tried once more , though still same result: ![wall_method_1](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/2X/a/a116d10950e8cd1e64bec5da2651b5301e9e3b49.png) ---

Not sure why it’s not working for you. Tho if you use the Grimshaw node, you could create the list of wall types like so to save some time: ![2015-02-04_135421](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/2X/6/6d66ba52c549434de793a7affaccf7691284787f.jpg) ---

that is a neat approach, and will come in handy Dimitar ---

Hope you resolved this; Nevertheless - it seems that it’d work if you just write Type in the string instead of “Type”;.
