Control dynamic block using parameters

myio — Wed, 22 Nov 2023 16:49:15 GMT

Good day,
as a construction fire safety designer, I draw the fire-hazardous area into floor plans - I work in AutoCAD LT 2022.

If the fire hazard area is determined by detailed calculation according to Eurocodes, then a SPLINE is drawn from the window.

SPLINE is defined by points:
- window width (2 points still on a line)
- a point far from the center of the window
- 2 points from the each edge of the window
- 2 points located behind the edge of the window

I'm trying to make it so that I change certain parameters in the dynamic block and then the vertices of the SPLINE would change depending on these parameters:
- window width
- center distance
- edge distance
- distance from the edge in the X axis
- distance from the edge in the Y axis

I am attaching a picture to better describe my problem:

Is it even possible to create such a dynamic block in AutoCAD?

For the standard calculation of the fire hazard area, I have created another dynamic block in which I change the width of the window and the distance of the fire hazard area, or the angle - it works correctly for me, I have attached it for a better understanding.

Thank you for your help.

Michal

In e.g Inventor (and some other products surely too) such manipulations are possible, but not in AutoCAD (and even less so in LT).

I'm pretty sure you could create an autolisp that would do what you ask or atleast make it easier to.
