A multipart project is a project which contains multiple models, instead of only one. Also they are stored with different file extensions, while single model files get the extension ".dat", multipart projects use the extension ".mpd".
The program can distinquish the different formats automatically when loading them, and suggests the right format when saving them.
Example: You create a model of a large train which consists of serveral equal cars. Here it makes sence to create one models for a car and include that into the train project. When not using MPD the models has to be included by hand (because it apears not in any part list), and if this model is published in the internet, all the submodels would have to be published as well. MPD is a big help because it keeps all the submodels together in one file, but working is the same as with normal sub-models.
The MPD project is created automatically when the first sub-model is added.
Select "MPD/New model..." from menu. A dialog will be displayed where the input of the model name (.dat file-name) as well as the description is required. Click the OK button to add the new sub-model. The program creates a new empty model and displays it on the screen. If this was the first sub-model added the program switches to MPD-project mode and activates the drop down list in the "Model Part List" area.
Select "MPD/Change model info" from the menu. The same dialog as when adding a sub-model will be displayed.
Change the name or the description and click the OK button when finished.
To delete a sub-model select "MPD/Remove model". From the list of models show in the opened dialog select the model to delete and click the OK button. If this sub-model was currently displayed another one will be shown instead. If the last sub-model was deleted the program reverts back to normal single project mode.
In the "Available Parts" pane and in the "Part preview" pane there is a section called document. In this section all sub-models are displayed. Drag the sub-model from one of this panes into the active model.
The program will check for recursive
inclusions and display an error if that would happen.
Example:
- The project consists of 3 models A, B and C. Model A includes
model B, and model B includes model C.
- Valid operations are: Including model B again into A or
including model C into model A
- Invalid would be to include model B into model C, or to include
model A into model C
In order to view the building steps of a sub-model, or to modify a sub-model the sub-model has to be active (that means it is displayed on the screen).
To activate a sub-model select "MPD/Select model" from the main-menu. In the opened dialog select the required model and click the OK button.
From the sub-model listbox which is displayed in the "Model Part List" area, you can also switch the sub-models.
In it's current form MLCad does not display building steps recursivly. That means MLCad generates building steps for every sub-model in the sub-model order.
Therefor it makes sence to set the order of sub-models as they have to be build.
To change the order of the sub-models as they will apear in the generated file, select "MPD/Sequence" from the menu. In the dialog reorder the models as required.
To create normal models select "MPD/Export models" from the menu. In the dialog enter the path where to save the files and click the OK button.
To import models select "MPD/Import model" from the menu, select the file to import in the dialog and click the OK button.
