surface links with shape inside

[ForgeLink_Engineering]

hello all,

i have a problem with surface links. How do i get a shape between surface links and normal links? In the preview window i have only a parallel surface line but it should fil lthe area between slope and bottom of the concrete. Any ideas? attached my problem:

Hi @ForgeLink_Engineering 

From your SAC screenshot, it seems you don’t have a shape defined for this area! You need to create and code a shape for this area, but the code can be something you have used before. (It’ll have a shading color is SAC when the area has a shape assigned, right now it’s white!)

Hope this helps,

i have shape and code defined but the area isnt closed. thats why i am asking, how can i close that? ther must be a way to close surface links. I did now with vertical line L154 but this is not ok as the surface link shall go directly to the bottom of the concrete...

maybe @KMercier_C3D ? any help is very welcome!

Perhaps you need an Intersection Point. You might need to turn on the option to Extend Link 1 and Extend Link 2.

Can you post the subassembly file?

attached the pkt file. it doesnt work with intersection as the surface is shown as horizontal. I am very advanced in SAC but this issue i couldn't solve. Thanks! 

 the section type is located here...

Surface links create their own start/end points. You want to make sure that the end point of one link in the shape is the exact same point as the start point of the next link all the way around the shape. 

Here is a list of your links and their points to make that S27 shape as currently in your PKT file: 

• L152 (P114,P39)
• L58 (P36, P49)
• L154 (P49, P120)
• L153 (P115,P116)
• L157 (P116, P114)

From this you can see that your shape isn't connected at P36 and P39 or at P115 and P120. You can close this shape by adding a link from P36 to P39 (this link will have a length of 0 if the points are the same location which is fine) and a link from P115 to P120. If you add these two links to your shape your shape should close and calculate.

 @KMercier_C3D  thanks for your input, will try. but before i do, how do i stop the green surface link at the red line? now i have given the link at left P.x till right P.x width. but it should follow the surface till it gets at the elevation of a given link. How shall i do that?

How can we search for where L58 is being created?

Make an auxiliary surface link (AP1, AP2, AL1) that is long enough that you know it will pass through the red link. Then use an auxiliary intersection point (AP3) between the red link and the auxiliary surface link (AL1). Then make your green surface link using the end point as AP3.x.

@tcorey

You can find where a link is created by clicking on it in the Preview window and it will highlight the flowchart location.

Thank you, Kati.

can you tell me how you realized that P39 and P36 are not closed? the points are exactly overlapped, but you were right that these 2 points created the issue. I added a line between them and it worked. 

[KMercier_C3D]

The computer doesn't know they are at the same location though so you need to connect them to close the gap in the shape. This is common with surface links since they create their own start/ end points. Because of this I try to make my surface links first, with auxiliary geometry earlier if needed so that I can use the surface points to create my shapes to begin with and not have overlapping points.

you need to make the surface link first and then make normal link those from start and end point of that surface link, it should be like this for your sample
