-====== Building a bike model ======+====== Instrumental Pedal Tutorial ======
 =====Overview===== =====Overview=====
-This tutorial outlines the process to build a model for a bike pedal and crank and how to assign force data from analog signals. This tutorial assumes your human model is already built. Follow this tutorial to create a model before continuing [[https://www.wiki.has-motion.com/doku.php?id=visual3d:tutorials:modeling:building_a_6_dof_model&s[]=building&s[]=model|Building 6DOF Model]]. This tutorial will have two parts, the first part will show how to create the model for the bike pedal and crank, and the second will show the force data processing. Full completed CMZ can be downloaded here: {{ :visual3d:tutorials:modeling:bikemodeltutorial.cmz.zip |Bike Model CMZ Complete}}. The final CMZ should resemble the following noting the moving forces on the feet from the pedals. +This tutorial outlines the process to build a model for a bike pedal and crank and how to assign force data from analog signals.

 ===== Model Building ===== ===== Model Building =====
-Building this model is very tedious as there are a lot landmarks and segments required. It is important to follow the order outlined below as certain landmarks and segments are build off previously defined items. To create a new landmark click on the **Landmarks** tab, select **Add New Landmark**, input the definitions below and press **Apply**. +The create a model you first need to load the dynamic trial into the workspace. From here select the **Model** menu and select Hybrid model from c3d file {{.:pasted:20260615-173245.png}}. Open your static trial which should generate the dialog below, ensure you check the dynamic trial to be built with this model.

Not that when inputting the definitions below the pedal landmarks and their offsets are specific to this dataset and would need to adjusted for different data

 +Once your model is complete you should save the model template for future use. This is done by selecting **Save Model Template File** {{.:pasted:20260615-172908.png}} and enter the desired name and file location. This model template can be applied to future dynamic trials with the same marker set-up. To apply a premade template follow the steps above to build a model from your static trial but once loaded select **Load Model Template** {{.:pasted:20260615-174536.png}} and add your desired template.
