Disegno 2D


By The Bricsys Team 5 min 11 febbraio 2024

If you've been using the same CAD solution for a while, you may have an extensive library of Dynamic Blocks. BricsCAD® is 100% read-only compatible with Dynamic Blocks, so you can open a file containing Dynamic Blocks in BricsCAD V24 and even edit their parameter values using grips.

However, you can't dive into the underlying block definition to change, remove, or add an action. So, we have developed a range of parametric operations, including BLOCKCONVERT, so you can still work with your blocks when you switch to BricsCAD® by converting Dynamic Blocks to BricsCAD-native parametric blocks.

How to edit Dynamic Blocks in BricsCAD®

When you want to edit the underlying definition of a Dynamic Block, use the BLOCKCONVERT command. Let's take a look at how it works!

Dynamic Blocks bricscad table 2d

We'll start by changing the table's appearance in the example below by giving it rounded corners and changing the color of the seats.

  • To open block definition options, use the BEDIT command and choose the "Tab_Chr" block from the dialog.
  • Since you can't edit the block definition, BricsCAD will ask if you want to convert the block.
  • Click "Yes" from the command line prompt.

In the enhanced BLOCKCONVERT command dialog, you can see that most block definitions are ready for conversion.

  • Check the "Replace block definitions" box in the output options of the dialog.

This will convert the block definition within the current DWG file and directly replace existing block references in the active space with block references to the newly created block definition.

  • Click the "Convert" button.

Back in the model space, you can see that the appearance of the table with the chairs block has changed.

How to Edit Block Definitions in BricsCAD® V24

Now, we can use the BEDIT command!

BEDIT pblock

  • When the command dialog appears, choose the new "Tab_Chr_pblock" definition.

FILLET command

  • Enter the FILLET command to give the table more rounded corners.
  • Set the radius to 20.

FILLET polyline

  • Select the polyline option.
  • Save the block.

table stretch

You can see that there is something wrong with the table, so let's check the stretch operation.

Parameters Manager panel

  • Use the BEDIT command again to navigate to the Parameters Manager panel.

Here, we can see that one parameter icon is different - this is the stretch operation!

Stretch edit selection

  • Right-click on the icon and choose "Edit selection." This will let you reconstruct the stretch frame, which defines the stretch points.

In this example, we box-selected the entire right-hand side of the table, making sure to include the vertices of the rounded corners.

The "Animate" option in the Parameters Manager panel lets you validate the new stretch behavior and see if it works as expected.

Now, to change the color of the chair.


  • Enter the ARRAYEDIT command, click "Source" in the command line prompt, and select both backseat hatches as the source.

Change color

  • Open the Properties panel and choose the color you want - we chose cyan in this example.
  • Click on "Save Changes" to exit the ARRAYEDIT command.
  • Click on "Save Block" to exit the BEDIT command.

Result Converted and Edited Parametric Blocks

You have successfully converted your Dynamic Blocks to BricsCAD's Parametric Blocks, edited their block definitions, and changed their appearance! You can quickly start working with your existing Dynamic Blocks in BricsCAD using the BLOCKCONVERT command - so there's no need to worry about losing your block library when you switch to BricsCAD.

Converting PDF to DWG files with BricsCAD®

You can convert PDF files to DWG files quickly and easily in BricsCAD®. When you convert a PDF to a DWG file, BricsCAD® converts straight lines to polylines, true type fonts to MTEXT, and filled solids to hatches, giving you a working drawing file in place of your PDF! Here's how you can do it!
