How to calculate area in CAD
Thread Content
Could some expert please advise me on how to calculate the area of a cross-section in CAD? I know how to use the area command, but I can’t make use of it; I have no problems with some simple shapes. But if the graphics are complex, it’s very difficult for me. When I use the ‘area’ command to calculate the area, I need to select the nodes of the cross-section, but it’s impossible to determine the points for some arcs. For example: consider a circle from which two arbitrary radii are drawn from the center; find the area of the arcs formed by these two radii. I just want to ask how to make use of this command effectively. Thank you
Select all the outer contour lines of the area whose size you want to determine, define them as a \"domain\", then press the \"Polygonal Area\" shortcut key. Select the newly created domain, and its area will appear at the bottom of the screen
2# Wanli Guyun, how do you select the arc line? ! If your graph is linear, it can be selected. But what if it’s an arc? You can’t select an area precisely; please discuss this in more detail
Do you want to find the area of a sector? The method I mentioned above does not use the “area” command; instead, it uses the “region” command and the “massprop” command. When creating the domain, only the outer contour line of the sector is retained; all excess parts must be cut off. If you insist on using the “area” command, then I won’t use it, hehe
I remember that it’s possible to set boundaries; once they’re set, it’s possible to calculate things, and there’s room for further discussion...
