Generic pattern based family.

rahid_mullas — Sun, 02 Feb 2025 19:36:47 GMT

I have created a block of 400x200mm in generic pattern based family template. To show the grouts I have created a void around the edges. When I load this family on to the mass surface which is flat to the ground. The pattern comes perfect. But when title the pattern by dragging the points. It says pattern can't be created. Immediate help pls.

@rahid_mullas

could be several reasons. Example

not properly constrained/constructed
The surface stretched to an extent where the panel is no longer suitable the pattern on that surface

one would need to check both the panel and the surface in order to know what exactly is wrong

Here is the familty that i am aattaching for your refrence. i dint constrain any geomery or void form as i am confused how this geneic pattern based template works.

@rahid_mullas

You did not include the mass/surface or curtain system you are applying it to.

Nontheless, that family is pretty much basic with no constraint at all. As is, such panel would work as long as the surface is vertical or horizontal. If you wish to apply it on a tilted face, try to tilt the surface using the edge and not the verticies. When you stretch the surface using one of the verticies it becomes skew (defined by 2 different planes) and that panel is not suitable for such applications. You will need to model an adaptive panel in such case

See below videos for a better understanding of how each works:

@RDAOU First of all thank you. this video was very usefull i learned a lot from this video. i have made the family but when i load this into the project it it says cant make type "rectangle:Interlock block".

@rahid_mullas

That most likely means that

either the value of one of the parametric constraints is not working properly
or one or more of the reference points in an adaptive component not properly hosted

Hard to say without the family. You need to flex it before you load into the model

Here it is. i though i have included everything. just cant figure it out where i am going wrong. its just that its the interlock bring of 400x200mm and i am also trying to show grout at the edges. you can see in the family. without the grout it makes fine. but with the grout as void you can see it gives the error. pls let me know where i am going wrong. its the simplest geometry but still this many complications. @RDAOU

@rahid_mullas

There is one reference point loose, you need to define it with a parameter (grout width)...it is easy to see that when you flex the grid in the family. I do not have 2021 so I cant really fix it for you. But doing it on your own also helps you become an expert 🙂

Some of the points are not properly hosted as well (See image below)

Moreover, You do not need voids. simple host the reference points by intersection and form the tile with the inner rectangle

Then extrude a second form from the outer border for the grout

Thank you so much. i have created a parametric family. now even if i change the vertices it doesnt break.it responds now. thank you again.

Did i accept the solution?

Thank you it was very usefull. i have created a parametci family for. thank you so much
