Keyboard cad dynamic blockblock5/3/2023 I know I can explode each door block as I insert it, and then I am free to edit each block individually, without affecting the others. But, if I want one of the doors to be 33" Wide, and if the parametric drawing is in a block, editing one of the doors to be 33", will cause all door blocks to become 33" wide. Suppose I start with all the doors being 30" wide. In BricsCAD, because you cannot create DBlocks, it has been suggested that I use parametric drawings. With DBlocks, you can use just one block definition, but have each individual instance of the door block a different size. So, here is an example An architectural drawing needs 4 doors in the drawing, with some of them at 30" wide, and others are 33" wide. I am not sure if you understood what I posted, or perhaps I misunderstood you. One thing that should be solved is when using arrays of parametric items, those should now remain parametric instead of becoming "dumb" 3D solids Dunfee said: I haven't got to testing yet in V19 if the abovementioned issue of the parametric values resetting to the default still happens. The parametric values however should remain unchanged for already inserted blocks unless specified otherwise. It could be due to user error though when creating the parametric objects.Īny updates to the geometry of the block should propagate to all inserted instances, as that is how blocks are supposed to work. I've run into this issue when I started using parameters and assemblies. It is possible to edit the parameters in the drawing after insertion, however when doing an update of an assembly it may happen that the inserted parts will revert back to their default value. This was long before dynamic blocks were a twinkle in Autodesk's Dunfee said: After entering the proper information, the block would come in with its own name. There used to be 3rd party software applications for AutoCAD v12, that gave the user the ability to create a parametric drawing, and the user could insert a part with this software. It would not be a viable approach for most things. I only needed a simple rectangle with a few minor add-ons, and a text label of the part#. However, creating that script in Excel is a lot of work. Then, it will convert it to a block and insert into the drawing you were working on when you started the process. I have created a spreadsheet in Excel, and it has a VBA utility that will open a new drawing, take a series of BricsCAD commands placed in Excel cells to draw an object. There needs to be a process to open the parametric drawing, and then insert it with perhaps a set of attributes that describe the dimensions and/or part# chosen. If you edit it as a block, then all instances of the block will change. The problem with just creating a drawing using parametrics, and then inserting it into BricsCAD, is that there is only one definition for that block. Or watch it on YouTube here.I also think that it should be possible to automate the process. There are a few steps that you can save by using this LISP. The LISP routine allows you to select objects then choose the block to add objects. You can download Add Objects to Block LISP from Lee Mac here. Using Add Objects to BlockĪutoCAD users can use AutoLISP to do this faster. Select the objects that you want to add to your block.Ĭlick Save Changes on the Edit Reference panel. They are in the working set.Ĭlick Add to Working Set on the Edit Reference panel. You can see now the objects on your block are more visible than the other objects. Right-click and click Edit Block In-place from the context menu.ĪutoCAD asks for confirmation to select the block that you want to modify. Select the block that you want to modify. If you need to see objects in your drawing, you need to use another method. Using Block Editor is not suitable because you only see objects in your block. Sometimes you need to add existing objects in your drawing to your block. If you use a block for this purpose, you need to modify the block regularly. There are many reasons why you should use AutoCAD blocks ( at least we can list 5 of them here).Ī block can make a complicated drawing simpler. We often need to modify a block definition.
