If your software has expired enter the new license key when requested. Please contact one of the sales team (sales@grantadesign.com) who will send you a new license key that will re-activate the evaluation for a suitable length of time. In general, if display problems arise, we recommend checking that you have the latest drivers for the video card installed or turning off graphics acceleration.
This problem has been observed when using a Matrox Mystique video card under Windows 95 (not Windows NT). This was fixed by turning off graphics acceleration in the system properties.
This problem has been observed when using an ATI Rage 128 video card, running under Windows NT4.0.
CES remembers the last unit system that you used. If your new database does not contain a unit system that matches it, then CES can not select it, and chooses to use none.
The most likely cause of this is that you are using some type of constant in your combined property - for example - 8.314 * [Melting Temperature]. When you change unit system, the value of [Melting Temperature] is changed to reflect the new unit in which it is measured in the new unit system, but the constant has no units and its value is not altered. To assign a unit to a constant, you should open the database in CES Constructor, go to the 'Database' menu at the top of the screen, select 'Database Properties' and select the 'Constants' tab. Here you can create a new constant, and assign it a unit.
It is possible to search all records in the database for text strings, but a selection can not be made from the results.
You need to select the 'Pick Tool' from the 'Graph Stage' toolbar before you can make a selection in a grid.
In a CES database, if a value is left blank in CES Constructor, the datasheet in CES Selector shows a value of 'Not Applicable' for that record. For convenience, there is a setting to hide such values in CES Selector, under Tools > Options > Datasheet. When making a selection, a setting in the properties for a stage determines whether records with a value of 'Not Applicable' pass or fail any selection criteria.
Click on the 'Stage Properties' button, or pick 'Stage Properties' from the 'Select' menu at the top of the screen. On the 'Selection' tab, choose 'Below the line' instead of 'Above the line'.
Click on the 'Stage Properties' button, or pick 'Stage Properties' from the 'Select' menu at the top of the screen. On the 'Stage' tab, change the 'Pass when' option to 'Whole Record in Selection'
First of all, find the record either using the 'Find' tool, or by
navigating to it in the tree. Right click on the record and Select 'Highlight'.
The record will now flash on all the graphs. If you still can not find
your record - it may be hidden on a chart, or may be failing a limit
selection rather than a graph selection - then click on the 'Select' menu
at the top of the screen, and select 'Results'. In the dropdown box
that says 'All Stages', select 'Pass/Fail' table, and find the record
that you are looking for. a cross indicates that it has failed a stage,
a tick that it has passed.
This has been fixed in CES4.5. It is a bug in CES4.1. If during a selection you change a parameter from the default (e.g. Temperature to 300°C), and save the project. When you load the project back into Selector, the Temperature parameter will not be changed to the project value, but will remain at the default value. Therefore the bubbles will appear to move or disappear. To resolve this problem you must manually change the parameter to the project setting (in this case 300°C).
The metric unit for density in the CES 4.1 database has been change from Mg/m^3 to kg/m^3. The actual values will appear to be 1000 times larger than previously. This change was made to make the CES Metric unit system more consistent.
A table can have up to 255 'fields'. A range attribute consists of two fields (the upper and lower limits). Therefore if a table contained only 'range' attributes, the maximum number of attributes permitted is 127. If a table contained only say 'discrete' attributes, then the maximum number of attributes is 255. If Constructor warns you that you cannot add more attributes, compact the database and try again. You can find this option in the 'Tools' menu at the top of the screen by selecting 'Check and repair'. If you want more than 255 attributes, please contact sales@grantadesign.com.
When you add a new attribute to a table, it is automatically added to the 'All Alphabetical' form. If you then open a record and you cannot see the attribute, check which is the current form set for the table. You must add this new attribute to each form in which you wish to see it. This is done by selecting a form, and then selecting 'Edit Form' from the Edit menu. Add the 'available attribute' under a form 'heading'.
If you want to use a filter that you have just created, you have to double-click on it to set it as the active (current) filter, and then double-click on the table that the filter belongs to. This will take you to the tree-based view of the data table, and allow you to add records to the new filter.
Right click on the filter or form in the 'Database' tab of the 'Control' window, and select 'Set as default'
Go to the 'Database' menu at the top of the screen, select 'Database Properties' and set the 'Selection Table' to be the one that you want to use
In the 'Database' tab of the 'Control' window, right click on the table that you wish to hide. Select 'Table Properties' and tick the 'Hide in CES Selector' box.
The best way to do this is to add your new materials to the existing Materials tree, and the checking will be automatic. You can set up a filter on the Materials tree which only contains your materials, so that when you use that filter in CES Selector, only your new materials are shown. If you wish to have a completely new table, then you have 2 options. You can make a copy of the materials table, and delete all the existing records - this will leave all the attributes and their units intact. Alternatively, you can create the table from scratch. Once you have created your new table, you can then follow the instructions in the 'Checking' topic in the on-line help in CES Constructor (accessed through the 'Help' menu at the top of the screen).
The records you have added to the database have not been added to the filter that you are viewing in CES Selector. Either add them to the filter (in CES Constructor) or change the filter in CES Selector to one that contains the new records.
The most likely cause of this is that in CES Constructor you deleted the table that CES Selector uses as the Selection table. To set a new selection table, open the database in CES Constructor, go to the 'Database' menu at the top of the screen, select 'Database Properties' and set the 'Selection Table' to be the one that you want to use.
Link buttons cannot be moved, and always appear at the bottom of a form.
Numeric range, functional range and functional point data can be flagged as estimated in a CES database, but point and discrete data cannot.
The simplest way is to set up filters and forms in the database tailored towards the groups that will be using the database. However, there is nothing to stop one group from using the forms and filters of another group. If it is necessary to completely restrict access to certain parts of the database, then use the following procedure. For each group, make a slave copy of the master database. Set up a form and filter on each table in the slave that contains the information that they are allowed to view. Copy this table, and then choose 'Paste Special' from the 'Edit' at the top of the screen. You are then prompted for a form and filter to copy the table through. This ensures that only those records and attributes that are shown in the selected form and filter will be put in the copy of the table. Once this procedure has been completed for every table in the slave database, delete the original tables, and make the slave database available to the group that will use it.
When you create a new table in CES Constructor, use the table template that matches the type of data you have. This will add appropriate units and parameters to the database. A workaround that results in a more comprehensive set of units is to take a copy of the master CES database (data.gdb) and delete all the tables it contains. This will leave a blank database, but with all the units, constants and parameters intact. You will need to compact this database before adding data to it.
One of the forms in your table has not been copied.
This functionality is not available. There is no workaround.
Right click on the record, select 'Record Properties' and pick a new colour in the 'Tree Colour' drop down box.
It is necessary to compact the database when you have deleted data from it. You can find this option in the 'Tools' menu at the top of the screen by selecting 'Check and Repair'.
This has been fixed in CES4.5. In earlier versions, any '.' in the attribute name or units will be changed to '#' during the import. On the import screen you can change these back to '.' manually.
This occurs when you create expression data which is not dimensionally correct, i.e. the units on either side do not match. The only solution to this problem is to correct the expression, or delete all the unit systems apart from the one that the expression was built in.
This is a bug in CES4.5. You can download a new currency file from here to fix this. |
