WARNING 000594: Input feature -1: No support for this geometry type.

Hello everyone,

We are getting this error message when appending a FC point into a FC Multipoint using Model Builder.

Executing (Append): Append  ......

How can it be fixed?

It seems it expects a multipoint object and not a single point object. A multipoint is not a point.

The field shape from Input Dataset comes from a View that select the field .SHAPE from a multipoint FC, but it looks like it does not keep the type multipoint and it converts it to point. so when I  run an append it shows this error.

[DanPatterson_Retired]

are these las data? or does it just happen to be a 'simple' multipoint?

You have placed this in modelbuilder, so I will say no, but in python scripting, you can append to the points list of a multipoint.  Perhaps the purpose of your workflow might be useful. since your limits in modelbuilder would be the 

Processing multipoint data tools, which presumably you have ruled out

[JoseSanchez]

I am running a Python script but when I append the SDE view point to a FC point it fails with the message above.

[DanPatterson_Retired]

as expected, since a point is not a multipoint, so you have to make the multipoints into single points or vica versa prior to appending.  SDE... hmmm don't know if that has any added complications, but if you need to append then you have two options.  But the question still remains, what is the need for a multipoint in the first place? and if it is needed, then you need to get the geometry into the same form

[JoseSanchez]

So how to convert a single point to a multipoint  in a feature (record) or feature class ?

[DanPatterson_Retired]

you have to make a multipoint featureclass first, then add the point as a list to it as shown in the code example in the previous example.  As for multipart to singlepart, there is automatically a tool for that

[JoseSanchez]

I am testing that and it works:

[DanPatterson_Retired]

yes.... from above copying will copy in the right form

you have to make a multipoint featureclass first, then add the point
