Universal Columns are the most widely used structural steel section. Additional information regarding the properties of UC sections can be found Here. StructX has proved the following free AutoCAD blocks that can be used to aid with structural drafting.
Hello AUGI Members, I work for a structural engineering firm and I am new to dynamic blocks. I am trying to create a dynamic block to be used as a steel beam in plan view. This block would be inserted from the connection point of one column to the connection point of another column and would be represented by a solid heavy line that is cut back, a certain distance, from each connection point.
My block had 3 linear parameters (1) for the 'cut back' length at one end of the beam, (1) for the solid line of the beam and (1) for the 'cut back' length at the other end of the beam. I have attached the drawing of the block to see if anyone can provide me with some guidance in completing this dynamic block.
The goal would be to insert the block by selecting the two connection points and having the DB placed between the (2) connection points with the 'cut back' lengths set at a specific distance, such as 10 inches. Any assistance with this would be appreciated. Regards, Vince. You could create a tool palette for the block and have default values for each instance. It appears so far there has been little programming with lisp and DB's. Though you could try a search. Is what I came up with.
IMHO tool palettes with the most commonly used values would be your best, easiest, and less time consuming bet. It also is more visual for those users which are less lisp routine savvy.i recommend using this from the Tool Palette as well. You can set all the values fo the parameters by r-clicking the TP button and customizing the properties. You can also set the layer as mark mentioned, so it's always inserted where it's supposed to be. Chris, I had developed a lisp routine that would ask the user to select 2 points (connection points) for the beam and would draw the beam on a designated layer with the ends cut back automatically.

The program would then ask the user for the member designation and would remember it for subsequent beam placements (for example W12x50). Next the routine would calculate the length and angle of the member and insert a tag that would display the member designation at the center of the beam. The tag would also contain invisible attribute fields containing the beam size, length and description that were provided by the lisp routine.

In other words the beam went in semi smart with the information contained in the attributes. We had another program that would do a take-off of all of the members on that drawing. There is another routine that would allow the user to copy and reposition an existing beam and update the attribute tag at the same time keeping the report information up to date.
A problem developed when an individual did not use the tools to copy and reposition the existing beams and we wound up with beams that looked correct when printed but the attribute information was totally incorrect. I was looking for a better method for accomplishing this task and a dynamic block seemed like it would work but I did not know much about them. It appears that from a graphic standpoint the DB would work but I would need to be able to capture and modify the custom DB information (distance, angle, distance1, etc.) with the lisp routine to make this effective. I hope I answered your question.once again thank you for your help in this effort. Regards, Vince.
