Assembly Challenge Using the components in the file. Assemble the shelving unit and provide a detailed modelling story board using the correct constraining methods. Shared > Design & Tech > Adv Higher > Assembly Modelling Exercises Start with the Top. Remember you can use other tools to support you in completing the model.
Assembly Challenge Answer I used centre align to line up the dowels and then mate to position it them the correct depth in the hole. To position the side I used align and mate. I used align the faces to line up the front edge and side with the top and then mate to join them together . To position the dowels for the shelf I had to change their orientation using by aligning the centre axis and then used mate to join the flat of the dowel with the depth of the hole. I had to change the orientation of the shelf and I used mate and align to position the shelf. I used mate to join the side surface of the shelf to the side surface of the side and align to bring it into alignment with the front of the side. Extra command I used to help me complete the project more efficiently were: Rectangular pattern and mirror.
