Has anyone used the (modeling 2d) trim or trim_dia commands? The only help I can get that kind of explain it is the sha_punch_functions.lisp in the SheetAdvisor folder. and it only tells me that I need to use points of time type.

Hello CSPalmer84,

for further information about the commands you mentioned, you need to execute the following function.

Code:

---

(oli::sd-online-reference)

---

Afterwards you'll find a new entry in your tool-box named 'Online Reference'. Using this online reference you can obtain the informations you are looking for.

Hope this help.

Bst rgrds,

   Alex

trim-test.lsp

First at all i did like to excuse this misunderstanding. I thought that you are looking for the documention of this commands.
A closer look at the trim command and a first test showed me that it is not that easy. But finally i found a way - see attachment.

The trim command expects viewport raw pick informations as elements instead of selected items. 

Bst rgrds,

I saw this too late and i'm about to leave the office. This isn't going to help me too much as I'm using get_selection and I don't know how to get the :raw-vport-pick through that. :-/

but thank you for your assistance. Have a good weekend

I have found an alternative answer for this that will allow you to do this via a local-function or defun option.

If you want to do it by elements, you will need to get the both element's end points and construct a GPNTWC 3d-point where you will get the :z position from the workplane and then creating the GPNTWC variable as following (or at least this worked for me)

(sd-read-from-string (format nil "~A"
    (format nil "(GPNTWC ~A ~A ~A ~S)"
        (* 25.4 (gpnt3d_x Elem1_MidPnt))
        (* 25.4 (gpnt3d_y Elem1_MidPnt))
        (* 25.4 (gpnt3d_z WP_Center))
        "vport1")
  ))

**This next part may translate weird for some if you're using chome**
What I found to be easier though was to over draw everything past the each other elements, using a get_selection to gather them all into a variable, and then using (trim :contour All_Elements) and that created the profile that i wanted.

Thank you for sharing your solution.

Best regards,

Yes, interesting and mentally taxing. The finalized code can produce welds on one or both sides of the cylinder.

Though, now they want one that wraps all the way around it  . Oh well, just another project to do
