Update Derived Drawing

Drawing > Itemisation/Detailing > Derive > Update derived drawing

Use this function to update already existing derived drawings after applying changes to the model drawing. Furthermore, updating a derived drawing enables you to close gaps in the model drawing which can, for instance, occur when superfluous views have been deleted.

When you call the function, the Update derived drawing dialogue window will be displayed:

1. Select the sheet you want to update from the Sheet selection list box. If you only want to update the active sheet, select Active sheet. If you want to update all sheets, select All.
2. In the Part selection section, specify which parts you would like to take into account for the updating:

• All
• Only changed
• Select individually
• Selection list

3. Specify additional settings by activating/deactivating the checkboxes.

Update only BOM and title block	If only the BOM and the title block of the drawing are to be updated, activate this checkbox. All other changes such as scale, dimensions, designations or new sectional views will not be executed. The contents will - if necessary - always be updated. If this checkbox is active, then all other checkboxes will be inactive. Important: Tags (e.g. the diameter of standard bores) have an absolutely set base point in the workshop drawing. If the bore is moved, the base point will remain in the original position and the position of the base point will no longer match the bore. This may create situations where tags point to the wrong bore.
Rearrange views	If you do not want to rearrange the views of the updated sheets, e.g. because you want to retain your own arrangement of views, deactivate the Rearrange Views checkbox.
AutoSync sectional views	Via the AutoSync sectional views checkbox you can specify how to handle sectional views that are still missing, and sectional views that are no longer needed. If you activate the checkbox, the following will happen: After the adding of new attached parts in the model drawing, the corresponding missing sectional views will be generated automatically. After the deletion of attached parts in the model drawing, the corresponding superfluous sectional views will be deleted automatically. Example Workshop drawing of beam (1) Updated workshop drawing after deletion of the front plate (2)
Rearrange dimensions and annotations	If you have manually created or arranged dimensions or annotations in drawings, you can specify that these dimensions/annotations and their arrangement will be retained when the drawing is updated by deactivating the Rearrange dimensions and annotations checkbox. However, the contents will automatically be corrected if necessary. Keeping the dimensions/annotations can only work if the Adjust scale to frame size checkbox is inactive in the drawing derivation. Please also note the following: Processing the drawing manually may result in creation or omission of new dimension base points or annotations in the drawing. In such cases, it is not possible to retain the corresponding dimensions and annotations. This means that these dimensions and annotations will be newly created when the drawing is updated and you must subsequently adjust them again accordingly.

4. To carry out the update, exit the window with OK. If you have activated the Select individual entry under Part selection, HiCAD will prompt you to identify the desired steel component.

 

Rearrange bills of materials (BOMs)

BOMs that are aligned to the drawing frame (option Quantity list in drawing frame.../Structure list in drawing frame...) are only rearranged when updating derived drawings if the views are also rearranged. This means that the checkbox Rearrange views must be active.

If no rearrangement takes place, HiCAD still ensures that the fixed point of the BOM corresponds to the settings of the drawing derivation.

Example:

If the BOM is arranged in the top right corner, then the top right corner of the BOM will still be in the top right corner of the view frame. If the BOM has become longer or wider, then - to ensure this - it is moved if necessary.

 

Please note:

• To create a selection list, press and hold down the CTRL key and identify the steel engineering parts you want to update - either in the ICN or in the drawing. You can also select the parts by drawing a rectangle: Press and hold down the CTRL key and use the left mouse button to draw a rectangle around the required drawing detail. Then activate the Update derived drawing function.
• If you are processing beams that have already been itemised, the item numbers of these parts are assigned a negative sign. You will need to re-itemise the changed beams before updating the workshop drawing.
• If you have added further parts/assemblies to your drawing, the existing views will be retained during workshop drawing modification. Additional drawings are, depending of the filter settings, inserted.
• Frames for view groups are automatically adapted if the size of a view group has changed.
• If you want to delete a view of a workshop drawing, use the deletion functions for views - either in the Views tab of the ICN or in the Graphic window.
• Manually deleted section views of a workshop drawing remain deleted, even when the drawing is updated. However, this only affects the respective view group the section view was deleted from. If other drawings exist for the corresponding part, the section views in this view group are unaffected. If the section view of a double stiffener is deleted, the two stiffeners will not receive a section view, even as single stiffeners.
• When loading drawings with an updating of referenced parts, the workshop drawing will not be automatically updated.
• Individually generated 2-D/3-D views, sectional and detail views will be retained and geometrically updated when drawings are updated.
• For external PDM-managed drawings you can now specify in the Configuration Editor whether missing sectional views are to be created in case of an updating of derived drawings. To do this, select PDM > Automatic drawing derivation > Production drawing, and set the parameter AutoSync sectional views when updating PDM-managed drawings as desired. Default setting is 1 (adjust).

When adding view groups on drawing sheets with already existing views from a drawing derivation, you have also the option to prevent the rearranging of the views if desired. In the Configuration Editor, select PDM > Automatic drawing derivation > Production drawing, and set the parameter Rearrange views when updating PDM-managed drawings as desired. Default setting is 1 (rearrange).

• If the scale changes for the views of a workshop drawing, manually created views will also be adjusted when the workshop drawing is updated. Linked views will be retained, i.e. the aligned linking of manually created views will be kept after the scale change. For detail views or limited sectional view, the appropriate relative scale change will be applied.
• For annotations in workshop drawings, the FTD files will be evaluated according to the current settings in the Configuration Editor, at Automatic drawing derivation > Production drawing > Usage-dependent > name > Annotation . name is the name of the corresponding usage.
• If an automatically generated dimension, i.e. a dimension based on dimensioning rules, is deleted in one view of the workshop drawing, this dimension will not re-appear when updating the workshop drawing!

More specifically the procedure will be as follows as of HiCAD 2017 SP1:

• The selected dimension will be deleted and will not re-appear when updating the drawing.
• The dimensioning rules set saved in the workshop drawing data for the view groups of the selected dimension will be adjusted so that the dimensioning rule for that dimension will be omitted in the respective direction and view. HiCAD will point this out by showing the following message:
  
  

If this message should no longer be displayed during the current HiCAD session, please activate the Suppress message checkbox.

• All other dimensions of the view that were created with the same dimensioning rule and in the same direction as the deleted dimension, are converted to interactive dimensions and preserved when the drawing is updated.

If you do not want this behaviour you have the possibility to turn it off in the Configuration Editor under System Settings > Annotations > Dimensioning, 3-D by deactivating the Rework when deleting workshop drawing dimensions checkbox. This is recommendable if a loss of performance can be noted in workshop drawings with many views.

The new behaviour only works with workshop drawings created in or updated in HiCAD 2017 SP1!

• If the perspective of an axonometric view is changed in a workshop drawing that was created with the Derive drawing function, e.g. by rotating the view, the perspective will be maintained, even when the drawing is updated. Automatically created shortenings are recalculated accordingly. However, manually created shortenings will not be retained.

 

Please note:

If you move a view from one sheet of the workshop drawing to another (via Drag & Drop), HiCAD will issue the following message:

After performing the action, the corresponding views will no longer be considered for the updating of the workshop drawing.
