Please let me know how I can get entire blocks and layers and their properties

[shivajitheboss]

Hi,

I just wanted to know how I can get all the available blocks in the drawing and how I can filter blocks from available product categories? The same thing I also want to know for the layers as well, I want to get a list of available layers programmatically and product categories.

Could you please help me with this.

Thanks;
Shiv

Hello Shiv,

You can get all the blocks and layers through CADImage.Converter.Blocks and CADImage.Converter.Layers collections, respectively:

Code: Select all

CADEntityCollection blocks, layers;
blocks = this.CADImage.Converter.Blocks;
layers = this.CADImage.Converter.Layers;

To filter out blocks and layers by a certain value of their (CADBlock or CADLayer class) property, you may use a List<T>.FindAll() method. The given method retrieves all the elements (CADEntity objects) that match the conditions defined by the specified predicate and can be called on any CADEntityCollection instance.

Could you please tell what you mean by product categories? I might help you with the Predicate<CADEntity> delegate that defines the conditions of the collection elements to search for.

Thanks a lot for your help, Mikhail. Product categories mean like in my drawing there are different types of blocks and layers are available. Some of the blocks belong from hypermarket, few of them are from supermarket and remainings are from grocery market products, so I want to display blocks as per block categories. Could you please help me how I can filter them.

Hello Shiv,

Thank you for the information.

Is the product category reflected in a block name? Let's say, "Hm_Product1Block", "Sm_Product1Block", "Gm_Product1Block", where "Hm" means hypermarket, "Sm" means supermarket and "Gm" - grocery market.

Are you guys working on the same project?

Hello,

In case the product category is reflected in a block name, you may use the following predicates with the List<T>.FindAll() method:

Code: Select all

Predicate<CADEntity> blocksFromHyperM = new Predicate<CADEntity>(entity => (entity as CADBlock).Name.StartsWith("Hm"));
Predicate<CADEntity> blocksFromSuperM = new Predicate<CADEntity>(entity => (entity as CADBlock).Name.StartsWith("Sm"));
Predicate<CADEntity> blocksFromGroceryM = new Predicate<CADEntity>(entity => (entity as CADBlock).Name.StartsWith("Gm"));

List<CADEntity> hmBlocks = this.CADImage.Converter.Blocks.FindAll(blocksFromHyperM);
List<CADEntity> smBlocks = this.CADImage.Converter.Blocks.FindAll(blocksFromSuperM);
List<CADEntity> gmBlocks = this.CADImage.Converter.Blocks.FindAll(blocksFromGroceryM);

For better understanding of a Predicate delegate in C#, please refer to the following article:

Thank you for your help, Mikhail. In my drawing, there are around 80 blocks and they are having any random names like ( "GL-50", "DL-30", etc), so if I want to categorize them then do I need to filter them one by one? because I can't see any product category when I am reading them from code.

Hi Shiv,

How can you understand which block refers to which product category? Is this reflected in the block name or in any other way?
