Where can I find a ready search set for LOD 450 ?

hello, finding a ready-made search set for a specific Level of Detail (LOD), such as LOD 450, in Navisworks might be a bit challenging as it often depends on the specific project requirements and the available data. However, you can create your own search set in Navisworks to filter and organize objects based on LOD or any other criteria. Here's a general guide on how to create a search set in Navisworks: 1. **Open your Navisworks project:** - Launch Navisworks. - Open your project file or import the necessary models. 2. **Go to the "Find Items" tab:** - In the ribbon at the top, go to the "Home" tab. - Click on the "Find Items" button in the "Selection" panel. 3. **Create a new search set:** - In the "Find Items" window, click on the "Search Sets" tab. - Click the "Add" button to create a new search set. 4. **Define search criteria for LOD 450:** - In the "Search Set" tab, you can add rules to define the search criteria. For LOD 450, you may need to use properties such as "LOD" or specific attributes related to the level of detail. - Click on the "Property" dropdown to select the relevant property, and set the condition accordingly. For example, if LOD is specified in a "Comments" property, you can create a rule like "Comments contains LOD 450." 5. **Save the search set:** - Once you've set up your search criteria, click "OK" to save the search set. 6. **Apply the search set:** - Go back to the "Find Items" window and select your newly created search set. - Click "Search" to filter the items in your Navisworks model based on the defined criteria. Keep in mind that the availability of specific LOD information in your model will depend on how the models were created and whether the relevant information is included in the properties or metadata. If you're working on a specific project or with models provided by others, you may need to coordinate with the project team to ensure that LOD information is consistently applied and available for use in Navisworks. Additionally, you might need to customize the search set based on the specific properties or metadata used in your project.

What Tolerance value should kept during clash test

[@bim360]

The tolerance value for clash tests in Navisworks, or any similar clash detection software, depends on the precision required for your project. Clash tolerance represents the allowable distance between the clash objects for them to be considered as clashing. Here are some considerations: 1. **Project Precision:** - For projects requiring high precision, a smaller tolerance (e.g., 1-5 mm) might be appropriate. - For projects where a higher level of precision is not critical, a larger tolerance (e.g., 10-20 mm) could be acceptable. 2. **Model Scale:** - The scale of your model can influence the appropriate clash tolerance. Smaller models may require tighter tolerances for accurate clash detection. 3. **Project Requirements:** - Check the project specifications or requirements. Some projects may specify a particular clash tolerance based on industry standards or specific project needs. 4. **Performance Impact:** - Keep in mind that tighter tolerances can increase the computational load and processing time for clash detection. Consider the performance impact on your system. 5. **Collaboration:** - If you're collaborating with other teams, it's essential to agree on a clash tolerance that is feasible and practical for all parties involved. Ultimately, the clash tolerance should be set based on the specific needs and constraints of your project. It's advisable to communicate with your project team, including architects, engineers, and other stakeholders, to determine an appropriate clash tolerance that aligns with project goals and requirements.
