Subassembly for undercut

[dprelipceanuWJVLH]

Hi,

I need to create a subassembly for this case.

P1 is a feature line and P2 is the back of walk from corridor.

I need to follow the slope 1:1 from P1 and 1.5% the undercut.

Can anyone help?

Thank you very much.

Check to see if I read your message correctly.  Assuming I did, the following should help.

• The slope from P1 is 1:1.   I'll call this line L1.
• The line from P2 down is vertical.  I'll call this line L2.
• The slope of the line leading from L1 to L2 is 1.5%.  I'll call this L3.

What version are you using?  If C3D2024 or newer, they FINALLY made it possible to use AND SHARE a custom subassembly.  So I would look at using SAC to generate this:

• Place an Auxiliary link (AL1) from P1 down the given slope.  Distance won't matter at this point.
• Create L2 from P2 down the appropriate depth.
• Create an Auxiliary link (AL2) from the bottom of L2 the appropriate slope.  Again, distance won't matter at this point.
• Create a Auxiliary Point (AP1) at the intersection of AL1 & AL2.
• Create a link connecting P1 to AP1.
• Create a link connecting AP1 to the bottom of L2.

Please see attached the PKT file.

What I want is

• P1 to be Back of walk
• P2&L1 to be the depth of undercut
• L2 to have 1.5%
• L2 to have variable length
• P3 to be variable
• L3 to have 1:1 slope
• P4 target to the feature line in elevation and offset

What is the slope of the line highlighted in yellow?  I can't tell from your screenshot what is supposed to be all the different links and points.  I'll go with 2:1.  You should be able to modify my PKT file as needed --my goal is to point you in the right direction so you can figure it out.

• Download the file.  I used SAC2024.
• Rename the file so it has a pkt extension instead of a zip.
